timm/mini-imagenet

Dataset Description

A mini version of ImageNet-1k with 100 of 1000 classes present.

Unlike some 'mini' variants this one includes the original images at their original sizes. Many such subsets downsample to 84x84 or other smaller resolutions.

Data Splits

Train

• 50000 samples from ImageNet-1k train split

Validation

• 10000 samples from ImageNet-1k train split

Test

• 5000 samples from ImageNet-1k validation split (all 50 samples per class)

Usage

This dataset is good for testing hparams and models in timm

Train

python train.py --dataset hfds/timm/mini-imagenet --model resnet50 --amp --num-classes 100

Citation Information

For the specific instance of this mini variant I am not sure what the origin is. It is different from commonly referenced Vinyales et al.,2016 as it doesn't match the classes / splits.

Train & validation splits match train & test of https://www.kaggle.com/datasets/ctrnngtrung/miniimagenet ... it is not clear where that originated though.
