Concept Learners for Few-Shot Learning

Kaidi Cao*, Maria Brbić*, Jure Leskovec

This repo contains the reference source code in PyTorch of the COMET algorithm. COMET is a meta-learning method that learns generalizable representations along human-understandable concept dimensions. For more details please check our paper Concept Learners for Few-Shot Learning (ICLR '21).

Dependencies

The code is built with following libraries:

Getting started

CUB dataset

Change directory to ./filelists/CUB
Run source ./download_CUB.sh

Tabula Muris dataset

Change directory to ./filelists/tabula_muris
Run source ./download_TM.sh

Usage

Training

We provide an example here:

Run python ./train.py --dataset CUB --model Conv4NP --method comet --train_aug

Testing

We provide an example here:

Run python ./test.py --dataset CUB --model Conv4NP --method comet --train_aug

Tabula Muris benchmark

If you would like to test your algorithm on the new benchmark dataset introduced in our work, you can download the data as described above or directly at http://snap.stanford.edu/comet/data/tabula-muris-comet.zip.

Dataset needs to be preprocessed using preprocess.py. Train/test/validation splits are available in load_tabula_muris.

Running this code requires anndata and scanpy libraries.

Our codebase is developed based on the benchmark implementation from paper A Closer Look at Few-shot Classification.

Tabula Muris benchmark is developed based on the mouse aging cell atlas from paper https://www.nature.com/articles/s41586-020-2496-1.
