# Dataset Card for ImageNet-100

ImageNet-100 is a subset of the original ImageNet-1k dataset containing 100 randomly selected classes. In addition, the images have been resized to 160 pixels on the shorter side.

- **Homepage:** https://github.com/HobbitLong/CMC
- **Paper:** https://arxiv.org/abs/1906.05849

## Dataset Structure

### Data Instances

An example looks like below:

```
{
  'image': <PIL.PngImagePlugin.PngImageFile image mode=RGB size=160x213>,
  'label': 0
}
```

### Data Fields

The data instances have the following fields:

- `image`: A `PIL.Image.Image` object containing the image.
- `label`: an `int` classification label.

The labels are indexed based on the sorted list of synset ids in [imagenet100.txt](https://raw.githubusercontent.com/HobbitLong/CMC/master/imagenet100.txt) which we automatically map to original class names.
