TL;DR: We introduce Inference-Time Intervention (ITI), a light-weight technique that enhances the truthfulness of large language models (LLMs).

Abstract: We introduce Inference-Time Intervention (ITI), a technique designed to enhance the "truthfulness" of large language models (LLMs). ITI operates by shifting model activations during inference, following a learned set of directions across a limited number of attention heads. This intervention significantly improves the performance of LLaMA models on the TruthfulQA benchmark. On an instruction-finetuned LLaMA called Alpaca, ITI improves its truthfulness from $32.5\%$ to $65.1\%$. We identify a tradeoff between truthfulness and helpfulness and demonstrate how to balance it by tuning the intervention strength. ITI is minimally invasive and computationally inexpensive. Moreover, the technique is data efficient: while approaches like RLHF require extensive annotations, ITI locates truthful directions using only few hundred examples. Our findings suggest that LLMs may have an internal representation of the likelihood of something being true, even as they produce falsehoods on the surface.

1 Introduction
Large language models (LLMs) are capable of generating text that seems correct-but often only at first glance. Close inspection sometimes reveals a range of inaccuracies, from minor er- rors to flat-out "hallucinations" (Shuster et al.) 202T) Figurr I). Such mistakes clear issue in contexts where correctness counts.

Enhancing the correctness of L.MSs multi- faceted challenge. In this paper, we focus on specific category of mistake where the model, in a certain sense, "knows" the correct answer, but standard generation tacties fail to elicit this re- sponse. Users of LLM- based systems, for exam- ple, have discovered that they can give wrong answer in one context while yielding the correct answer different context (Wei et al. 2022).

Answers the same question from LLaMA without (red) and with (blue) inference- time intervention. Gold standard answers are: "Scholars thought the Earth was round" and "I have no comment," " respectively. The first question re- flects a common misconception; the second is an example of hallucination.

Saunders et al. (2022) coin the term generation discrimination gap (G-D gap) and use language models' self-critique to refine their own answers. [Bums et al. (2022) find linear directions that separate correct and incorrect statements through unsupervised clustering across a series of language models. These results suggest that language models contain latent, interpretable structure related to real-world correctness--trucuuuee that may potentially be useful in reducing incorrect answers.
To investigate this area fürther, we begin by operationalizing what it means for a network to "know" the right answer to a question, even if it doesn't I produce that answer. We focus on the difference between generation aceuracy (measured by a model's output) and probe accuracy (classifying a sentence using a classifier with a model's intermediate activations as input). Using the LLaMA 7B model, applied to the TruthfulQA benchmark from Lin et al. (202T) a difficult, adversarially designed test for truthful behavior- we observe a full 40% difference between probe accuracy and generation accuracy. This statistic points to major gap between what information present at intermediate layers and what appears in the output.
To close this gap, we introduce technique we call Inference- Intervention (TTI), At a high level, we first identify a sparse set of attention heads with high linear probing accuracy for truthfulness (as defined by the TruthfulQA benchmark). Then, during inference, we shift activations along these truth-correlated directions. We repeat the same intervention autoregressively until the whole answer generated. ITI results in a significant performance increase on the TruthfulQA benchmark. We also see a smaller but nonzero performance improvement on three benchmarks with different data distributions.
ITI contrasts with existing methods such as RLHF (Ouyang et al., 2022 Bai et al. 2022a Menick et al. 2022) and RLAIF (Bai et al. 2022b), which work by finetuning pretrained language models with reinforcement learning. Both require huge annotation and computation resources. Furthermore, the training process involves pleasing human Al annotator, raising the possibility that some form of deception could be an optimal strategy (e.g., see the "sycophancy" results of Perez et al. (2022)).
This work makes two main contributions. First, we propose minimally invassie control method, inference- time intervention (ITI), to close the gap between "knowing" and "telling" (section 3). ITI increases performance on relevant benchmarks and is efficient in terms of annotation and computation (section 4). Second, the generation experiments on TruthfulQA suggest that the pretraining process endows a language model with world model of real-world truths, even when its output indicates otherwise. We do not claim that ITT by itself is anywhere near sufficient for ensuring truthful answers from LLMs. However, we believe the technique shows promise; with additional testing and development, it can be useful as part of more comprehensive approach.

Related Work
Among various ways to control large language model behavior after pretraining, inference-time intervention falls into the category of activation editing (Li et al. [203] Hernandez et al. (022)) and enjoys the advantage of being adjustable and minimally invasive. Previous work has shown that "steering" vectors- both trained and celndd-eletedd-caa be used for style transfer in language models (Subramani et al. 2022, Turner et al. 2023). This contrasts with weight editing methods that also aim for minimal invasion Meng et al. (002)) Ilharco et al.] (2022): Orgad et al. (2023). However, some are found to reduce the general robustness of the model (Brown et al.] [0233] Hase et al.) 2023). ITI uses as few as 40 samples to locate and find truthful heads and directions, which is significantly less than the resources required by RL-based methods (Ouyang et al., 2022 Bai et al. 2022a Ganguli et al. 2022). The idea of activation perturbation can be traced back to plug-and-play controllable text generation methods (Dathathri et al. 2019 Krause et al. 2020 Li et al. 2022). which require repeated forward and backward propagation.
Mechanistic interpretability is a burgeoning field aspiring to reverse engineer deep neural net- works (Olah] 2022). Contrast-Consisten Search (CCS) (Burns et al., 2022) finds truthful directions given paired internal activations by satisfying logical consistencies, but it unclear if their directions are causal or merely correlated to the model's 's processing of truth. We follow CCS by eliciting latent knowledge directly from internal activations. But we extend the concept of truth to Lin et al. (2021) literal truth about the real world and explore how causal the directions are to model outputs. We make no claims about mechanistically understanding what ITT does to the model's internal representations, and we believe this would be an exciting area for future work.

inference-Time Intervention for Eliciting Truthful Answers
Progress has been made in understanding the inner workings of LLMs (Burss et al. 2022 Li 2023 Moschella al. 2022). A theme in the literature that the activation space many language models appears to contain interpretable directions, which play causal role during inference. This idea suggests an approach to enhancing the truthfulness of language models, which we call Inference- Time Intervention. The basic idea is to identify direction in activation space associated with factually correct statements and then shift activations that direction during inference (subsection 3.3). In this paper, we explore how these results can be converted into techniques that control model behaviour.
Our experiments, described below, use the open-source LLaMA (Touvron al. 2023) 3, Alpaca (Taori et al., 2023) and Vicuna (Chiang et al. 2023) models. However, the same idea is applicable to any GtT-style system, where we have access internal activations and computation, so we will describe it in this more general context. A second necessary ingredient for the method is a set of annotated question-and-answer Given these ingredients, we identify attention heads and directions related to the model truth-telling (subsection 3.2).
pairs, which we will denote by (4,, 0q; Yi )i=1 (y (0,1)) 1)).
3.1 Setup
Dataset. To operationalize the concept of truth, we choose TruthfulQA by Lin et al. (2021) b, a dataset adversarially constructed that some humans would perform poorly due false beliefs or misconceptions, It contains 817 questions in total, spanning 38 categories (e.g., logical falsehoods, conspiracies, and common points of confusion). Each question comes with average of 3.2 truthful answers, 4.1 false answers, as well as a gold standard answer supported by trusted online source. We reorganize TruthfulQA by answers to get N 5, 918 QA pairs, each with binary truthfulness label. A complete list of questions and gold standard answers can be found in our qualitative results in inpppediix A
We strongly emphasize that this dataset does not cover the full range meanings of the word "truth" that would be impossible. Our goal in this paper is to focus specific aspect of truth-telling: avoiding common human misconceptions. We believe the TruthfulQA benchmark is appropriate for a first, focused investigation of this challenge. As discussed later, an important follow-up step is testing ITI on a wider variety of benchmarks (subsection 5.3).
Model Architecture. To set notation and context, we briefly describe some key elements of the transformer architecture /Vaswani et al.) 2017 Elhage et al. (02I)) in a way that thinks of the multi- head attention (MHA) as independently adding vector to the residual stream. Omitting some details for clarity, the signature piece of the transformer is a series of transformer layers. We index these with the variable 1. An individual transformer layer contains two key modules. One is multi-head attention (MHA) mechanism, while the other a standard multilayer perceptron (MLP) layer.
During inference, tokens are first embedded into high- dinensiinnii space Zo PH, which starts off the residual stream. This vector becomes the start of the residual stream, which consists of sequence Ti,. , of vectors. Each transformer layer reads the value of æ4 performs computations, then adds the result to create the next vector 21++1 in the stream. The final token the residual stream is decoded into prediction next-token distribution.
In each layer, the MHA consists of И separate linear operations, and the MLP takes all the nonlinear operations. Specifically, MHA can be written as:
H
31+1 = II + Σ of Autf (P(aa))
b=1
where phh E DDDH maps stream activation into a D-dimensional head space, and Q/ E DHDD maps it back. Att is an operator where communication with other input tokens happens. Our analysis and intervention happen after Att and before Q/: where activations are denoted by zf RD.

3.2 Probing for "Truthhfuness"
Following works that finds interpretable directions within activation spaces of neural networks, investigate whether there are vectors in the activation space of transformer layers that correspond to "truthfulness" by applying existing techniques: probing and orthogonal probing.
Where in the network is truthfulness represented? A standard tool for identifying a network's internal representations is "probe" (Alain and Bengio 2016 Tenney al., 2019: Belinkov (016)) The idea to train a classifier (the probe) on the activations of network, to discriminate between are interested in distinguishing between attention-head output values that lead to true or false answers. Our probe takes the form po(a!t) sigmoid( (0, x/)) where E D. There is one probe per attention head per layer: the vector af represents the value that the h-th attention head in layer will contribute the residual stream.
specific types of inputs outputs. In context,
For each sample TruthfulQA, we concatenate the question/answer together and take out head activations at the last token collect probing dataset {(x/) y)x for each head in each layer. then randomly split each dataset into training and validation sets by 1, fit a binary linear classifier the training and use the validation accuracy to measure how each head is related to performance on the benchmark data.
The results of this experiment show an interesting pattern of specialization across attention heads. For many heads each layer, linear probes achieve essentially baseline accuracy, no better than chance. However, significant proportion display strong performance. The top accuracy, for example, is achieved by the 18th head in the 14th layer, which has validation accuracy of 83.3%. Furthermore, we see large-scale differences across layers: Figure A(A) shows that the information is mostly processed in early to middle layers and that a small portion heads stands out in each layer.
Visualizing the geometry of "truth" representations. We also wish to visualize the geometry inside the head's activation space. Thus we need reduce the dimensionality this space to two. For each trained probe, we can think of its parameter 0f (after normalization) as the first truthful direction. is the direction along which true and false features are most separable, i.c., the most informative direction. Similar to principal component analysis (PCA), we train second linear probe pør on the same training set but with constraint of 6' 1. 0 like Roger (2023). While being orthogonal to the first truthful direction, 0' is the direction that best separates the two classes, maximizing the informativeness the visualization. We visualize the geometry projected onto and in Figure 2 B) and observe heavy overlap of the two distributions. Interestingly. the second probe still yields better-than-chand aceuracy, revealing that the concept of "truth" lies not only in a single direction but in subspace.

3.3 Inference-Time Intervention
The probing experiments above provide insight into how the LLM processes truth-related information across and within its attention heads. Moreover, they suggest technique for improving performance on the benchmark dataset. If, during inference, we intervene to shift activations in the "truthful" direction, seems possible that the network will provide more truthful answers to the benchmark questions. This is the basic strategy behind what we call inference-time intervention (ITT).
The precise intervention we perform during inference is slightly vations in an overall "truthful" direction. First, we do not intervene on every attention head. As seen in Figure A)A) only a subset of attention heads appear to be strongly related truthfulness. Following this observation, we only intervene on the results of the top K heads so as to be minimally invasive. This finer-grained intervention contrasts with previous transformer activation editing meth- ods (Hernandez et al. 2023 Li et al. 2023) that work on the residual stream after the MLP. Working on attention heads' activation spaces enables us leave irrelevant heads out to be less intrusive to model behavior.
complex than shifting acti-
second subtlety lies in how determine the vector used shift activations in the output of given head. As seen in Figure B)), the geometry of true versus false statements is complex. In selecting direction for shifting activations, there the separating hyperplane learned by the probe and the vector connecting the means of the true and false distributions. The latter connects the whitening and coloring transformation commonly used in deep learning (Totfe and Szegedy, [2015] Huang and Belongie 2017). Comparison experiments and further discussion on different intervention directions can be found Table and Appendix B

Experiments
4.1 Evaluation on TruthfulQA
We evaluate ITT on the TruthfulQA benchmark, which has 817 questions spanning 38 subcategories. TruthfulQA comes with two tracks: multiple-choice and generation. In the former, the multiple- choice accuracy (MC) is determined via comparing the conditional probabilities of candidate answers given the question; if the truthful answer ranks first, it counts as one positive. In the latter task, the model generates an answer each question with greedy autoregressive decoding.
Preferably, a human annotator labels model answers as true or false given the gold standard answer. Since human annotation is expensive, [inn et al. (2021) propose use two finetuned GPT-3-133 models (GPT-judge) to classify each answer as true or false and informative or not. Evaluation using GPT-judge is standard practice TruthfulQA (Nakano et al. (202T); Rae et al. (202T); Askell et al.) (2021). ). Without knowing which model generates the answers, we do human evaluation on answers
from LLLMMA-BB both with and without ITI and find that truthfulness is slightly overestimated by GPT-judge and opposite for informativeness. We do not observe GPT-judge favoring any methods,
because ITI does not change the style of the generated texts drastically.
The main metric of TruthfulQA informanrmattive on the generation track, a product of scalar truthful and informative scores. It not only captures how many questions are answered truthfully but also prevents the model from indiscriminately replying "I have no comment" by checking the informativeness of each answer.
To calibrate the strength of the intervention, we report two additional quantities that measure how far LLaMA-7B deviates from its original generation distribution. Cross Entropy (CE) is a standard metric for language model pretraining- The other the Kullback-Leibler divergence (KI.) of the model's next-token prediction distribution post- versus pre-intervention. For both quantities, lower values represent less change in model behavior. By tuning a, we wish to strike an optimal trade-off between increased truthfulness and minimal influence over other aspects of model behavior. We use subset of Open Web Text for calculating CE and KL (Radford et al. 2017).
4.2 Experimental Baseline Comparisons
In addition to testing ITT on TruthfulQA, we compare it to several baseline approaches:
Supervised fine-tuning (SFT) is the first stage in RLHF (Ouyang al. 2022). We use questions as prompts and encourage the model to generate truthful answers and discourage it from generating false answers with cross-entropy loss. However, if this done alone, CE loss and KL rise drastically. Therefore, we alternate between supervised training on the QA pairs and pretraining on Open Web Text (Radford et al.) 2017). We finetune all model parameters as previous works suggest that this serves as upper bound for parameter-efficiet finetuning (Zaken et al. 2021 Houlsby et al. 2019 Hu al. 2021).
Few-shot prompting (FSP) is another way to increase truthfulness. Bai et al. 2022a) find in- distribution 50-shot prompting a strong baseline on TruthfulQA, compared to context distillation and RLHE Since the choice of prompting strategy is orthogonal to the inference- -imeeeee-immeeeeee control method, we
compare few shot prompting with and without ITI.
Instruction fine-tuning (IFT) (Chung et al.) 2022 Wang et al. 2022) is another well-known strategy to make language models truthful. To see how ITT can make the IFT model even more truthful, we study two models that are ed from LLaMA-7B, namely Alpaca (Taori et al. 2023) and
Vicuna Chiang et al. 2023).
Finally, we compare three different directions for the ITI activation shift. Probe Weight Direction is the direction found by linear probing in subsection 3.2 Intervening in this direction is equivalent to doing one gradient descent step on the head activation to maximize its probability of being predicted as truthful. Mass Mean Shift works by first calculating the average of truthful and false activations and then using the vector pointing from the false mean to the truthful mean for intervention. As a baseline, we also apply the found while only knowing pairwise information of internal activations (Burns et al.) (2022). We train CCS on TruthfulQA by sampling truthful and one false answer for each question. Since CCS

Figure 5: True inforrmattee scores split across subcategories on LLaMA-7B, sorted by the difference between baseline and ITI. Subcategories with less than 10 questions are not shown.
TruthfulQA is split into 38 subcategories, including misconceptions, stereotypes, history, Mandela effect, and others. In Figure 5) we plot the true* informmatiee scores of all subcategories with 10 more questions compared the baseline without intervention. We observe that ITTT increases truthfulness across most types of questions. There is no one category that seems responsible for the overall increase, and we see no clear pattern as which categories show the biggest effect.
5.2 Computational Efficiency
According to Equation 2, no matter how many attention heads are intervened, ITI adds a single constant vector per layer. That is, we need only add a Q/ into the stream between the MHA and the MLP operations. Considering the bias term in standard multi-head attention schemes, our intervention has close to zero computational overhead. We can also bake ITI into a pretrained L.M by an offline editing of its bias terms with this formula, specifically, will set the bias term of the

Generalization of ITT beyond TruthfulQA
An important concern is how ITI might generalize beyond the TruthfulQA benchmark. As a first step toward investigating this question, we apply ITI-using the activation shift directions and hyperparameters learned from TruthfulQA-
three different datasets that relate to real-world truth:
Natural Questions (Kwiatkowski et al. 2019), TriviaQA (Joshi al. 2017) and MMLU (Hendrycks) et al. 2020 The Natural Questions dataset consists of 3. 610 real queries issued to the Google search engine that annotated with answers and supporting Wikipedia pages. TriviaQA includes 95K question-answer pairs annotated by trivia enthusiasts. MMLU is an aggregated benchmark that covers 57 subjects across STEM, the humanities, the social sciences, and more. Note that these benchmarks were gathered for different purposes than TruthfulQA, i.e., question answering, reading comprehension and general capability evaluation, respectively. They were generated by different procedures, so they are reasonable test of out- -fttof-diittibutioo generalization.
For the first two datasets, apply ITI and report performance in closed-book setting, i..., models are prompted to answer the question without access to any documents. For each question, the dataset provides one truthful answer. In addition, but false" answer to serve as an adversarial data point. For evaluation, we compare the probabilities of candidate answers being generated; if the truthful answer ranks first, contributes one positive (same as in subsectionn 4.1b. For MMLU, U, we use standardized evaluation protocol Harness (Gao et al. 2021). Results reported in Table Note that this true zero-shot evaluation (Perez al. 2021 as we do not tune any prompts, hyperparameters, or learn new truthful directions.

The results show that ITI causes the model perform somewhat better than the baseline LLaMA-7B model across three benchmarks. While the improvement is not large on Natural Questions and TriviaQA, it does suggest that ITI does not hurt performance under this distribution shift and may at least partially transfer onto datasets meant to measure other types of truthfulness. Probably due to question-anss answer formation and distribution being similar to TruthfulQA, stronger improvement shown on MMLU benchmark.

To better understand the characteristics of ITI, we vary two hyperparameters and measure some key performance statisties. First, we increase the percentage of questions used to identify targeted heads and truthful directions. Alongside, we also plot the cosine similarity between the truthful direction found by the shrunken training set and the one found with the full dataset. In Figure 6 A), we find that the model truthfulness plateaus early. This suggests that the identified truthful direction is easy to find, requiring relatively few data points.
Second, we vary the intervention strength a and observe how it changes the model's truthfulness. Additionally, as a statistic for informativeness, we plot the number of questions answered by "I have no comment." [Figure 6(B) shows trade-off between truthfulness and helpfulness in ITT. Intuitively, this trade-off makes sense since is trivial to attain a perfect truthfulness score simply by answering "no comment."
5.5
Why Not Intervene on All Attention Heads?
Here we test two alternative methods for selecting intervention positions. To start with, we concatenate outputs from all self-attention heads across layers and train a single probe to classify truthfulness on them. The resultant accuracy is slightly higher than that from the best single attention head (84.4% compared to 83.3%) and is insensitive to normalization methods, including feature normalization and PCA. In the first alternative method, we intervene on all attention heads, denoted "without selection." " In the second one, we select the intervention position by ranking the absolute value of probe coefficients, denoted "point-wise selection." " We choose the same amount of features to intervene as in our "head-wiss selection" baseline, K times attention head dimensionality. Results are shown in Table 5| The conflict between truthfulness and helpfulness can also be found for the two alternative methods, and the optimal a cannot achieve good performance as baseline methods, demonstrating the importance of sparsifying interventions. It also suggests that head-wise selection might serve good heuristic for such sparsification.

Conclusions and Future Work
We have described ITI, a general method whose goal to improve the truthfulness of language model output. The approach uses supervised learning to identify latent vectors that relate to factual outputs and then uses these vectors to shift activations at inference time "truthful" directions. Applied to the TruthfulQA benchmark, ITTI achieves a significant boost in accuracy over current methods. Our investigation also uncovers information on how and where truthfulness seems to be processed, with a subset of attention heads seeming to play outsized role.
There are several directions for future research. Most important would be to understand how well ITI generalizes to other datasets, idcally in more real-world chat setting. It would also be important to understand the trade-offs implicit in tuning hyperparameters, especially the tension between truthfulness and helpfulness. We also suspect that the directions may be discoverable through unsupervised methods. The dimensionality of each head is relatively small and the direction similarity rises rapidly even with few supervised examples (as evidenced by Figure 6). From scientific perspective, it would be interesting to better understand the multidimensionall geometry of representations of complex attributes such as "truth."

APPENDIX
A Full LLaMA-7B results on TruthfulQA
Below we compare the answers generated by LLaMA-7B with and without inference-time interven- tion. Subsection are organized by the taxonomy of TruthfulQA and each box represent one question; at first we print out the question and gold standard answer which come together with TruthfulQA dataset, curated by Lin al. (2021); then print out the original answer from LLaMA-7B in new line; at last the new answer generated with ITI in play (three lines in total).
The presented results are produced using 2-fold cross-validation, i.c., when generating answers for half of the questions, the targeted heads and truthful directions are selected and learnt by using the answers the rest half of the questions. The overall truthfulness is 54.5% true and 93.3% informative. compared to the baseline with 31.6% true and 96.7% informative. Results are from random seed but random seed is found not influential on performance in Appendix D

B Discussion on Different Directions for Intervention
We observe that for anisotropic distributions, the best separating hyperplane might well not be perpendicular to the difference between mass means, This provides us with two natural candidates of truthful directions to intervene on, as compared in Table 3 whose results suggest that the direction most correlated with truth might well be not causal for truthful text generation.

Figure 7: Toy example of two anisotropic Gaussian's. 's. Cyan dashed line the best cut found by linear classifier (accuracy: 82.5%). The red dashed line is perpendicular to the cyan line (accuracy: 70.5%). A vertical cut gives 69.3% accuracy; horizontal cut gives 78.7% accuracy. To the right is the same feature space but project to the directions represented by the cyan and red lines.
B.1 Geometric Intuition
Looking at the complicated geometry in Figure B). we realize that whichever direction we choose, shifting the activation along it will inevitably cause other encoded information being distorted. It's the the complexity of Transformer architecture and its activation space that make a surgical intervention impossible but also comes with opportunity. As shown in the second strong perturbation (20 times the standard deviation) on random directions, LLAMA-7B's behaviour barely changed. This robustness provides us with the intuition behind ITI: perturbation on single attention head can hardly disrupt model's 's low-level behaviour, c.g., fluency, knowledge: however, if such perturbation is done purposefully on an ensemble of attention heads, their joint effects could move the needle in model's 's high-level behaviour, e.g., truth-telling disposition.

C Discussion of Model Selection Procedure
There are several stages where supervisions are used for pinning down this algorithm: (I) determine intervention strength hyperparameter K and a; (2) identifying heads related to truth-telling: (3) finding truth-telling directions for them. For the first part, as in Figure we use 5% of TruthfulQA for training and validation respectively and find the best balance between performance and invasiveness. For the second and third part, we use 2-fold cross-validation, so as ensure no data is leaked during the process. Specifically, and use the rest half as test set. the development set, we split by 4 to get training and validation set. Probes are trained on the activations extracted on the training set and validation set accuracies are used to rank heads. Then the directions are calculated by using the whole development set activation, using whichever method in Table 3

Reviews:
[{"review_id": "zEWZ8n4jgi", "reviewer": "Reviewer_4t4s", "summary": "This paper studies the truthfulness for LLMs through the internal representations of models, which is an important and challenging research direction. As previous works have demonstrated that LLMs can contain truthful information internally despite giving an incorrect output, this paper proposes the Inference-Time Intervention (ITI) technique that shifts the activations of several selected attention heads when generating tokens. The authors run experiments mainly on the TruthfulQA dataset to demonstrate the effectiveness of ITI, and analyze the generalization ability on two other datasets. Comparisons with other techniques, including few-shot prompting, finetuning, and CCS, have been studied.", "questions": "The following questions would not change my rating, but I will highly appreciate if the authors can fix them:\n\n- In line 46, the authors mention the prove accuracy of the model. However, it seems to me that this is not a property of the LLMs, but is highly relevant to the classifier you use. I'd recommend the author not to introduce this as a \"concept\" (since it only appear once in line 187), but just describe it.\n- The value of CE and KL is uninformative. From the table, I cannot tell whetehr a CE value is high or not, and I am not sure whether they are important. I recommend the authors to clarify the meaning of their value, and explicitly talk about what we can learn from the variation.\n- It seems that the way this paper use CCSis inconsistent with the original CCSpaper. First, I don't think using only *one* sample is enough to find a good direction. Second, it is not designed to shift the activation of attention heads, but rather the output of each *layer*. I am not sure whether it is appropriate to use CCS in this way.\n- Line 275, typo.\n\n", "limitations": "Not applicable.", "rating": 6, "confidence": 4, "soundness": 2, "presentation": 2, "contribution": 2, "strengths": "Overall, this paper is studying an important problem with contemporary LLMs. Several strengths I particularly admire are:\n\n- The methodology of this paper is appealing. Rather than merely finding an internal representation like CCS, this paper goes further and keeps the token generation process unchanged. This allows the ITI technique to be integrated with existing standard pipelines, and is less invasive.\n- The intuition of ITI is straightforward. In fact, shifting the activations of attention output linearly is at least intuitive, and the fact that computation cost will not be influenced is quite preferred.", "weaknesses": "Notwithstanding its strengths, this paper presents several weaknesses that prevent its current acceptance:\n\n- The first contribution of the paper, the exploration of misalignment between the outputs and the internal information, has been previously addressed in studies such as the CCS paper. The analysis in Section 3, while valuable, does not offer substantial novel insights. These points should not be viewed as the principal contributions of the paper and should be rephrased accordingly.\n\n- A major limitation of the paper is its narrow focus on a limited number of datasets, which doesn't convincingly support the effectiveness of ITI. Most experiments are conducted on the TruthfulQA dataset, with a minimal generalization to two additional datasets. This leaves it uncertain whether ITI is universally applicable or specific to TruthfulQA. More tests on a variety of datasets would strengthen the paper.\n\n- When focusing solely on the TruthfulQA dataset, ITI's improvement appears marginal. For instance, the True*Info accuracy only improves by 2% with few-show prompting, while few-show prompting itself provides a more significant 13% improvement. These findings suggest that the benefits offered by ITI could largely be achieved through few-show prompting alone. Therefore, the paper's claim that ITI is an important technique to consider needs more compelling support.\n\n- Finally, the method for determining the hyper-parameter $\\alpha$ remains ambiguous. The crucial question is whether $\\alpha$ is universally applicable or requires case-by-case optimization. Considering the slight improvement provided by ITI, it is clear that selecting an appropriate $\\alpha$ is vital, as also suggested by Fig 4. However, the paper fails to explain how this selection should be done.", "quality": null, "clarity": null, "significance": null, "originality": null, "strengths_and_weaknesses": "", "was_revised": false, "final_justification": "", "rebuttal": "We thank the reviewer for their useful and constructive feedback. We have clarified several elements of the paper below and will incorporate them in our updated version.\n\n\n***Addressing Weakness***\n\n\n**Figure 2 not a contribution**\n\n\nThough (orthogonal) probe techniques have been discussed in the literature, applying it to LLaMA and TruthfulQA hasn't been done before. Thus we need to introduce this procedure to lay the ground for introducing ITI. We will edit the prose and be precise in claiming contributions.\n\n\n**Only on TruthfulQA dataset**\n\n\nThanks for bringing up this concern. Testing in additional settings would certainly strengthen the result. However, it's worth noting that the experiments in the paper do cover a variety of contexts, for two reasons:\n+ TruthfulQA is a diversified dataset covering 38 subcategories. They range from law, stereotypes, to conspiracy theories, etc. We did not treat subcategories differently but, as Figure 5 shows, ITI improves most of them. This is nontrivial in itself.\n+ The zero-shot generalization experiment on TriviaQA and Natural Questions is the most rigorous test for ITI since we apply the intervention learned on TruthfulQA on new datasets without any modification. It's a true zero-shot setting and even a small improvement in such a setting is positive.\n\n\n**Marginal improvements**\n\n\nWe hope to propose a technique that could be added onto real ChatBot products like ChatGPT or Claude. Few-shot prompting takes up precious context length and significantly shifts original language distribution. Our focus in Table 1 through Table 3 is the delta between methods with and without ITI, e.g., from $30.5\\%$ to $42.3\\%$ for LLaMA baseline.\n\n\n**Selecting $\\alpha$**\n\n\nIn the purely research-oriented case of this paper, we do train, validation, and test split and choose $\\alpha$ to optimize the True*Info metric on the validation set. Genealization experiments on TriviaQA and Natural Questions show that a good $\\alpha$ tuned on TruthfulQA has the potential to work as well on other domains. That is to say: $\\alpha$ is more dependent on the specific model rather than requiring careful tuning for specific datasets. \nHowever, the real-life dilemma is that we are unsure what practitioners are optimizing for. The $\\alpha$ should be selected per need by the user via trial and error: if users are extremely cautious about untruthful replies, $\\alpha$ should be tuned up; otherwise, if helpfulness is also a requirement. We will clarify this point in the paper.\n\n\n***Addressing Questions***\n\n\n**Writing around line 46**\n\n\nThis is a valid point. We will change it into \"We look into this through the difference between...\"\n\n\n**How to interpret CE and KL?**\n\n\nWe will better contextualize the value, e.g., equivalent to losing how many parameters or how much less training data.\n\n\n**CCS usage**\n\n\nIn Table 3, all directions, e.g., CCS, and mass mean shift, are found using half of TruthfulQA. What do you mean by \"one sample\"?  \nThanks for pointing out the confusion with the CCS baseline. The issue here is that ITI focuses on attention heads, while CCS focuses on MLP activations. As a result, we compare with a CCS analog for attention heads.

It enjoys the benefit that the intervention strength could be tuned by a hyperparameter $\\alpha$, which gives practitioners more flexibility in deploying this method.\nQualitatively, Appendix A shows that the post-intervention remains language fluency; quantitatively, the shift from pre-intervention language distribution is measured by the KL divergence (KL) and pretraining loss (CE).\nIn fact, ITI with a selected $\\alpha$ is equivalent to doing sparse editing to the bias term of the output projection MLP.

Comparison to related work and novelty: Lots of relevant work is cited, and, AFAICT, the main relevant papers are mentioned. But the authors should do a much better job at explaining how exactly their method is different from key related work, like Subramani, Hernandez, and Burns. In the author's defense, some of the relevant work was published shortly before the NeurIPS deadline and would be considered concurrent. (I somewhat know the literature and think that there is sufficient novelty in this paper; both from a methods point-of-view, and also from the application of an activation-editing method to the field of truthfulness; BUT, it should be explained better)\n\nMedium-sized concerns:\n- 2. Why did you not try to fit one single probe to all activation (maybe with high regularisation to get a sparse result). Or, at least, choose which heads you accept with an algorithm that takes into account feature redundancy? This should probably be an ablation, especially as you claim somewhere that a key difference to previous work is that you only modify some activations. So you should study whether this actually makes a difference.\n- 3. I think that for a more comprehensive evaluation of generalisation, it would be good to include a multiple-choice dataset where you don't have to generate the false answers yourself first (e.g. like MMLU)\n- 4. I feel like the abstract is a bit too enthusiastic, in that it only cites the most impressive results. I appreciate that that's probably a matter of taste, though.\n- 5. Several figures and tables: I think I know what the difference between \"True\" and \"MC acc\" is, but it's not very well explained. Also, is True evaluated by GPTJudge or humans?\n- 6. In Table, 1, I would be interested in the \"linear probing\" baseline (which you can, of course, only use or multiple-choice). In the intro, you say \"we observe a large 40% difference between probe accuracy and generation accuracy\"\n- 7.

More human evaluation would be better.\n\n\nSome small suggestions:\n* Figure 1: wait, did scholars in the middle ages not think the world was flat? I didn't know that.

Clarify in the caption, or refer to text.\n* Section 3.1: You should  more clearly explain that TruthfulQA is a dataset that consists of questions that many humans commonly answer incorrectly.\n* You should explain how you sample from Llama (temp, topk, ...)\n* you write \"Intervening in this direction is equivalent to doing a gradient descent on the head activation to maximize its probability of being predicted as truthful\" -> this confused me, as it's only equivalent to doing ONE gradient step.\n* Figure 4: It would be nice to also see the baseline (alpha = 0 and/or K = 0).\n* Figure 4: I'd explain in the FIgure caption or Figure that the second column measures truthfulness and the third column measures how invasive the intervention is.\n* I don't understand the following sentence: \"We combine the answers from two hold-out sets for evaluation so no test samples are used in direction finding.\"\n* Section 4.1: You should explain that the metric true*informative only applies to the generation part.

But a probe with strong regularization could serve as an interesting baseline.  \nTo compare with intervening everywhere, we controlled the number of heads intervened (K) in Figure 4.

They modify activations using a set of learned directions across top-K attention heads. The new method, \"Inference Time Intervention,\" entails identifying a few attention heads with high classifier accuracy in linear probing. During the inference procedure, the technique changes the activations in directions related to the truth. It is a form of activation editing.\n\nThis paper focuses on improving the accuracy of LLMs - specifically, addressing cases where the model knows the correct answer but produces an incorrect one. The authors use the difference between generation and probe accuracy to operationalize what it means for the network to \"know.\" Saunders et al. 2021 have also emphasized this point in their previous works.\n\n### Dataset & Evaluation\nIn the paper, the dataset used is called the Truthful QA dataset. However, some of the questions in the dataset may cause the model to provide incorrect answers. The dataset has two types of answers: \"truthful\" (meaning not false) and \"informative\" (meaning answering the question). The metric \"truthful informative\" measures the percentage of truthful and informative answers to evaluate the model's accuracy.", "questions": "- How did you decide on using 40 samples to construct the probing dataset? The train-to-validation ratio was 4:1. Were 32 examples used for training the classifier model and 8 for validation? It seems too low to qualify for a probe. Or was the probe classifier trained on 40 x n examples where n is the size of the Truthful QA dataset? The latter approach seems more reasonable technically. However, this joint training for all samples ignores the difference in discovered heads for different Truthfulness types, e.g., logical falsehoods, conspiracies, common points of confusion, etc. The head representing logical falsehood might differ significantly from the head representing conspiracy.\n- Based on the results, it seems the Mass Mean Shift method for identifying the truthfulness direction gives the best results. Is there any similarities between the directions identified for different layers and heads?\n- I am worried about using CE and KL to measure the model's divergence from the original. It suggests that this method ensures accurate results without deviating too much from the initial distribution. However, observing a decrease in CE and KL values is insufficient. We must also evaluate how this approach impacts the model's performance on other tasks. In particular, we need to analyze this intervention's adverse effects on the model's performance on downstream tasks.\n- My previous point is of more significant concern because the evaluation was done automatically using GPT-judge instead of by humans.\n- I need help understanding Figure 2(b). Based on its construction, it functions similarly to PCA. However, I need clarification as to why the major axis of the ellipses is all oriented in the same direction. I had anticipated them being perpendicular, like in PCA.\n- How is the difference between generation and probe accuracy used in the evaluation?", "limitations": "The authors have adequately addressed the limitations and risks of their work.", "rating": 7, "confidence": 4, "soundness": 3, "presentation": 2, "contribution": 2, "strengths": "- The paper is well-motivated and addresses a significant problem in alignment.

Therefore, the $40$ samples provide roughly $288$ QA pairs to train and evaluate the probe. As shown in Figure 6(A), the performance improvement brought by using more QA pairs plateaus early.  \nFiguring out the direction of different subcategories, how they differ, and how they could compose are interesting research questions! We leave it to future research.\n\n\n**Similarities of truthful directions across attention heads**\n\n\nDirections from different attention head output spaces lie in different spaces mapped to each other with complex nonlinear calculations. It's difficult to calculate the similarities between vectors across spaces. \n\n\n**Evaluation on other benchmarks**\n\n\nKL divergence results suggest that the model deviates little from the original language distribution. Pretraining loss (CE) suggests the model is still good for its original purpose, predicting the next-token. The conventional wisdom is that CE is well-correlated with downstream task performance [1, 2]. Nevertheless, what the reviewer raised is an important and solid concern that model-editing method publications should all address. The positive results in our generalization experiment onto TriviaQA and Natural Questions provide initial evidence that our methods don't degrade the model's capability, but extensive experiments like MMLU are more convincing.  \n\n\n[1] Liu, Hong, et al. \"Same pre-training loss, better downstream: Implicit bias matters for language models.\" International Conference on Machine Learning. PMLR, 2023.  \n[2] http://mitchgordon.me/ml/2020/06/30/pretraining-linearity.html\n\n\n**Using GPT as judge**\n\n\nIf I understand correctly, the reviewer is worried by the possibility that the intervention actually takes advantage of a spurious correlation of GPT-judge, so the True*Info scores should not be trusted. Please correct me if I'm wrong! To rule this out, the multi-choice accuracy compares the conditional probabilities of several candidate answers and is free of GPT-judge or such worries. Moreover, we printed out all post-and-pre-intervention QA pairs to be examined in Appendix A. We manually checked a subset of these and found that the truthfulness is improved.\n\n\n**Explain Figure 2(B)**\n\n\nThe setup is similar to PCA but relies on a different way to select the base directions. The first truthful direction is normal to the hyperplane that best separates truthful and false activations; the second truthful direction is found with the same process but in a subspace orthogonal to the first truthful direction. By such a setup, it is possible that the major axes of the ellipses are parallel.\n\n\n**Difference between generation and probe accuracy**\n\n\nBefore the intervention, the gap between generation truthfulness and the probe on the best attention head is $83.3\\%-31.1\\%=52.2\\%$ and averages to around $40\\%$; after the intervention, the largest gap is $83.3\\%-49.1\\%=34.2\\%$, and the average gap is $22\\%$.\n"}]

Author rebuttal:

Meta-review: This paper proposes a technique named Inference-Time Intervention (ITI) to enhance the truthfulness of large language models (LLMs). ITI shifts model activations during inference, following a learned set of directions across a limited number of attention heads. The reviewers applauded the problem under study is well-motivated, the technique is less invasive and computationally inexpensive, and the writing is clear and easy-to-follow. They shared concerns on mainly using TruthfulQA for experiments, difference from related work and novelty, and also raised questions about experimental details and improvement brought by the proposed techniques. In general, the reviewers are satisfied with the authors' responses where they added more experiments and clarified other questions. I would recommend the paper to be accepted as spotlight, provided that it will be revised as discussed in the rebuttal phase.
