    without repetition: In this paper, we present a general approach to extending
    pre-trained models to unlimited input lengths without adding additional learning
    weights. We show that our approach works well on datasets longer than the maximum
    input for these models. For example, a dataset with a maximum input length of
    16384 tokens can be extended to a maximum length of 350K tokens. We also demonstrate
    that our method is able to summarize even 350K token-long input sequences from
    BookSum.

    In this paper, we describe the search step reformulation of attention. The search
    step uses a single storage of hidden states for space efficiency. We construct
    a total of two sets of datastores where L and H are the keys and values stored
    in each set of stores. L is the amount of storage required to retrieve the encoded
    tokens. H is the hidden states per head. This allows retrieval augmentation at
    both time and space. Instead of using a single set of decoder layers, we use a
    retrieval augmentation system that allows us to simultaneously store multiple
    sets of tokens across two different sets of storage. For example, we could store
    all tokens in one set of storage and retrieve them all in the same set of tokens.
    This would be very similar to the Memorization Transformers approach. However,
    instead of storing the tokens in a single memory layer, we store them in a set
    of multiple storage layers. This way, we don''t have to store them all at once.
    This is why we call this reformulation ''attention reformulation'' rather than
    ''attention formula.'' We also call it ''retrieval augmentation'' because it uses
    the same number of storage layers as the original transformer attention formula.
    This means that we can store the tokens across multiple storage systems without
    having to store every token in a separate storage system. It''s not like we''re
    trying to do something new or different. We just want to make sure that everything
    is working as well as possible.

    In this paper, we introduce the concept of ''unlimiformer,'' which is a machine
    learning technique that retrieves key information from a data store in one layer
    and applies it to a large set of datasets. We use the example of BookSum, where
    we find that Unlimiform outperforms all other training methods on the same dataset.
    We also find that using Unlimform in conjunction with a pre-trained model improves
    both the performance and the robustness of the training method.

    This paper describes a method that can be used to improve the performance of unsupervised
    classification tasks. Specifically, it shows that unsupervised classification
    can be improved by using a combination of sparse and fast random-encoder training.
    It also shows how this technique can be extended to other tasks, such as sequence
    generation. '

<a href="https://colab.research.google.com/gist/pszemraj/df1989546b02f284d33ca4996f70fedc/flan-t5-large-instruct-example.ipynb">

</a>

This model is a fine-tuned version of [google/flan-t5-large](https://huggingface.co/google/flan-t5-large) on the pszemraj/dolly_hhrlhf-text2text dataset.

## Model description

text2text models fine-tuned on a [modified dataset for text2text generation](https://huggingface.co/datasets/pszemraj/dolly_hhrlhf-text2text)  based on the relatively more permissive  [mosaicml/dolly_hhrlhf](https://huggingface.co/datasets/mosaicml/dolly_hhrlhf) dataset.

Basic usage in Python:

```python
# pip install -q transformers accelerate
import torch
from transformers import pipeline, GenerationConfig

model_name = "pszemraj/flan-t5-large-instruct-dolly_hhrlhf"
assistant = pipeline(
    "text2text-generation",
    model_name,
    device=0 if torch.cuda.is_available() else -1,
)
cfg = GenerationConfig.from_pretrained(model_name)

# pass an 'instruction' as the prompt to the pipeline
prompt = "Write a guide on how to become a ninja while working a 9-5 job."
result = assistant(prompt, generation_config=cfg)[0]["generated_text"]
print(result)
```
> using the generation config is optional, can subsitute with other generation params.

## Intended uses & limitations

- this is **not** tuned with RLHF etc, and may output offensive results
- despite being the `large` tagged variant, this model has only 774M parameters (3 gb) and therefore may exhibit less 'cogitive ability' on some uses cases/tasks
