### Dataset Summary
**COYO-Labeled-300M** is a dataset of **machine-labeled** 300M images-multi-label pairs. We labeled subset of COYO-700M with a large model (efficientnetv2-xl) trained on imagenet-21k. We followed the same evaluation pipeline as in efficientnet-v2. The labels are top 50 most likely labels out of 21,841 classes from imagenet-21k. The label probabilies are provided rather than label so that the user can select threshold of their choice for multi-label classification use or can take top-1 class for single class classification use.

In other words, **COYO-Labeled-300M** is a ImageNet-like dataset. Instead of human labeled 1.25 million samples, it's machine-labeled 300 million samples. This dataset is similar to JFT-300M which is not released to the public.

### Supported Tasks and Leaderboards
We empirically validated the quality of COYO-Labeled-300M dataset by re-implementing popular model, [ViT](https://arxiv.org/abs/2010.11929). 
We found that our ViT implementation trained on COYO-Labeled-300M performs similar to the performance numbers in the ViT paper trained on JFT-300M.
We also provide weights for the pretrained ViT model on COYO-Labeled-300M as well as its training & fine-tuning code.
### Languages
The labels in the COYO-Labeled-300M dataset consist of English.

## Dataset Structure
### Data Instances
Each instance in COYO-Labeled-300M represents multi-labels and image pair information with meta-attributes.  
And we also provide label information, **imagenet21k_tree.pickle**.

### Data Splits

Data was not split, since the evaluation was expected to be performed on more widely used downstream task(s).

## Dataset Creation

### Curation Rationale

We labeled subset of COYO-700M with a large model (efficientnetv2-xl) trained on imagenet-21k. Data sampling was done with a size similar to jft-300m, filtered by a specific threshold for probabilities for the top-1 label.
