# Dataset Card for DataCompDR-1B

<!-- Provide a quick summary of the dataset. -->

This dataset contains synthetic captions, embeddings, and metadata for DataCompDR-1B.
The metadata has been generated using pretrained image-text models on [DataComp-1B](https://huggingface.co/datasets/mlfoundations/datacomp_1b).
For details on how to use the metadata, please visit our [github repository](https://github.com/apple/ml-mobileclip).

## Dataset Details

### Dataset Description

<!-- Provide a longer summary of what this dataset is. -->

DataCompDR is an image-text dataset and an enhancement to the DataComp dataset.
We reinforce the DataComp dataset using our multi-modal dataset reinforcement strategy.
In particular, we create DataCompDR-1B and DataCompDR-12M by reinforcing the DataComp-1B (BestPool filtering) and a uniform subset of 12.8M samples, DataCompDR-12M.
We have a one-time generation process, the cost of which is amortized over multiple architectures and extensive ablations.
We generate 5 synthetic captions per image using the `coca_ViT-L-14` model in OpenCLIP, and strong random image augmentations (10 for DataCompDR-1B and 30 for DataCompDR-12M).
We compute embeddings of an ensemble of two strong teachers (`ViT-L-14` with pretrained weights `datacomp_xl_s13b_b90k` and openai in OpenCLIP) on augmented images as well as real and synthetic captions.
Embeddings are 1536-D concatenations of 2x768-D vectors.
One seen sample for DataCompDR is a triplet of one randomly augmented image, one ground-truth caption, and one randomly picked synthetic caption.

## Uses

<!-- Address questions around how the dataset is intended to be used. -->

Training with DataCompDR shows significant learning efficiency improvement compared to the standard CLIP training.
For example, with a single node of 8×A100 GPUs, we achieve 61.7% zero-shot classification on ImageNet-val in approximately one day when training a ViT-B/16 based CLIP from scratch on DataCompDR-12M.
Training with DataCompDR-1B sets new state-of-the-art performance on several metrics (Fig. 2) while still using a fraction of the training compute budget compared to previous works.
Using DataCompDR, we demonstrate 10x-1000x learning efficiency in comparison to DataComp.
