EASE: Unsupervised Discriminant Subspace Learning for Transductive Few-Shot Learning (CVPR2022)

This repository is the official implementation of EASE: Unsupervised Discriminant Subspace Learning for Transductive Few-Shot Learning. This code is based on the Leveraging the Feature Distribution in Transfer-based Few-Shot Learning and Contrastive Laplacian Eigenmaps.

usage

Please download features from here and unzip it. This code can reproduce the performance in the paper, but something need to tune in different datasets like L2 normalization of prototypes and soft-labels (>1) for the computation of sinkhorn distance in the SIAMESE part.

If there is anything confusing you, please let me know.
