# Model Card for m4-80b |
|
|
|
<!-- Provide a quick summary of what the model is/does. [Optional] --> |
|
ATUM (**A**dapted **T**ransformers for **U**nstructured **M**ultimodal data) is an open-access reproduction of Flamingo, a closed-source visual language model developed by Deepmind. The multimodal model accepts arbitrary sequences of image and text inputs and produces text outputs and is built solely on public available data and models. |
|
ATUM (TODO) is on par with the original model on various image + text benchmarks, including visual question answering (open-ended and multiple choice), image captioning, and image classification when evaluated with in-context few-shot learning. |
|
|
|
The model comes into two variants: a large [80 billion parameters version](https://huggingface.co/HuggingFaceM4/m4-80b) and a [9 billion parameters version](https://huggingface.co/HuggingFaceM4/m4-9b). |
|
We also fine-tune these base models on a mixture of SFT datasets (TODO: find a more understandable characterization), which boosts the downstream performance while making the models more usable in conversational settings: (TODO: 80B-sfted) and (TODO: 9B sfted). |

|
|
|
ATUM is a large multimodal English model that takes sequences of interleaved images and texts as inputs and generates text outputs. |
|
The model shows strong in-context few-shot learning capabilities (and on par with the closed-source model), and is a robust starting point to fine-tune multimodal models on custom data. |
|
|
|
ATUM is built on top of two unimodal open-access pre-trained models to connect the two modalities. Newly initialized parameters in the form of Transformer blocks bridge the gap between the vision encoder and the language model. The model is trained on a mixture of image/text pairs and unstrucutred multimodal web documents. |
|
|
|
|
|
# Uses |
|
|
|
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. --> |
|
|
|
The model can be used to perform inference on multimodal (image + text) tasks in which the input is composed of a text query/instruction along with one or multiple images. This model does not support image generation. |
|
|
|
It is possible to fine-tune the base model on custom data for a specific use-case. We note that the instruction-fine-tuned models are significantly better at following instructions and thus should be prefered when using the models out-of-the-box. |
|

# Training Details |
|
|
|
We closel follow the training procedure layed out in [Flamingo](https://huggingface.co/papers/2204.14198). We combine two open-source pre-trained models ([laion/CLIP-ViT-H-14-laion2B-s32B-b79K](https://huggingface.co/laion/CLIP-ViT-H-14-laion2B-s32B-b79K) and [huggyllama/llama-65b](https://huggingface.co/huggyllama/llama-65b)) by initializing new Transformer blocks. The pre-trained backbones are frozen while we train the newly initialized parameters. |
|
|
|
The model is trained on the following data mixture of openly accessible English data: |
|
|
|
| Data Source | Type of Data | Number of Tokens in Source | Number of Images in Source | Epochs | Effective Proportion in Number of Tokens | |
|
|-------------|-----------------------------------------|---------------------------|---------------------------|--------|-----------------------------------------| |
|
| [OBELISC](https://huggingface.co/datasets/HuggingFaceM4/OBELISC) | Unstructured Multimodal Web Documents | 114.9B | 353M | 1 | 73.85% | |
|
| [Wikipedia](https://huggingface.co/datasets/wikipedia) | Unstructured Multimodal Web Documents | 3.192B | TODO | 3 | 6.15% | |
|
| [LAION](https://huggingface.co/datasets/laion/laion2B-en) | Image-Text Pairs | 29.9B | TODO | 1 | 17.18% |
|
| [PMD](https://huggingface.co/datasets/facebook/pmd) | Image-Text Pairs | 1.6B | 70M | 3 | 2.82% | | |
|
|
|
**OBELISC** is an open, massive and curated collection of interleaved image-text web documents, containing 141M documents, 115B text tokens and 353M images. An interactive visualization of the dataset content is available [here](TODO). |
|
|
|
**Wkipedia** is the multimodal equivalent of the encyclopedia. We used the English dump of Wikipedia created on February 20th, 2023. |
|
|
|
**LAION** is a collection of image-text pairs collected from web pages from Common Crawl and texts are obtained using the alternative texts of each image. We deduplicated it, following [this paper](https://arxiv.org/abs/2303.12733). |
|
|
|
**PMD** is a collection of publicly-available image-text pair datasets. The dataset contains pairs from Conceptual Captions, Conceptual Captions 12M, WIT, Localized Narratives, RedCaps, COCO, SBU Captions, Visual Genome and a subset of YFCC100M dataset. Due to a server failure at the time of the pre-processing, we did not include SBU captions. |
|
|
|
For multimodal web documents, we feed the model sequences corresponding to the succession of text paragraphs and images. For image-text pairs, we form the training sequences by packing images with their captions. The images are encoded with the vision encoder and vision hidden states are pooled with Transformer Perceiver blocks and then fused into the text sequence through the cross-attention blocks. |
|
|
|
Following (Dehghani et al., 2023)[https://huggingface.co/papers/2302.05442], we apply a layer normalization on the projected queries and keys of both the Perceiver and cross-attention blocks, which improved training stability in our early experiments. We use the [RMSNorm](https://huggingface.co/papers/1910.07467) implementation for trainable Layer Norms. |
|
|
|
The training objective is the standard next token prediction. |
|
|
|
We use the following hyper and training parameters: |

# Evaluation |
|
|
|
<!-- This section describes the evaluation protocols and provides the results. --> |
|
We closely follow the evaluation protocol of Flamingo and evaluate ATUM on a suite of downstream image + text benchmarks ranging from visual question answering to image captioning. |
|
|
|
We compare our model to the original Flamingo along with [OpenFlamingo](openflamingo/OpenFlamingo-9B-vitl-mpt7b), another open-source reproduction. |
|
|
|
We perform checkpoint selection based on validation sets of TODO, and select the checkpoint at step 65'000 for ATUM-9B and at step 37'500 for ATUM. The models are evaluated with in-context few-shot learning where the priming instances are selected from a support set to be similar (i.e. close in a vector space) to the queried instance. We do not use any form of ensembling. |

# Technical Specifications |
|
|
|
## Hardware |
|
|
|
The training was performed on an AWS SageMaker cluster with 64 nodes of 8x80GB A100 GPUs (512 GPUs total). The cluster uses the current EFA network which provides about 340GBps throughput. |
|
|
|
As the network is quite slow for the needs of DeepSpeed ZeRO-3 we were only able to clock ~90 TFLOPs. |
|
|
|
## Software |
|
|
|
The training software is built on top of HuggingFace Transformers + Accelerate, and DeepSpeed ZeRO-3 for training, and [WebDataset](https://github.com/webdataset/webdataset) for data loading. |
|
|
|
|
|
# Bias, Risks, and Limitations |
|
|
|
<!-- This section is meant to convey both technical and sociotechnical limitations. --> |
|
|
|
Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. (2021)](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. (2021)](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)). |
|
As a derivative of such a language model, ATUM can produce texts that include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups. |
|
Moreover, ATUM can produce factually incorrect texts, and should not be relied on to produce factually accurate information. |
|
|
|
Here are a few examples of outputs that could be categorized as factually incorrect, biased, or offensive: |
|
TODO: give 4/5 representative examples |
|
|
|
To measure ATUM's ability to recognize socilogical (TODO: find a better adjective) attributes, we evaluate the model on FairFace... |
