FREE

This repository contains the reference code for the paper "FREE: Feature Refinement for Generalized Zero-Shot Learning" accepted to ICCV 2021. [arXiv][Paper]

1. Preparing Dataset and Model

Datasets can be download from Xian et al. (CVPR2017) and take them into dir data.

Requirements

The code implementation of FREE mainly based on PyTorch. All of our experiments run in Python 3.8.8.

2. Runing

Before running commands, you can set the hyperparameters in config.py. Please run the following commands and testing FREE on different datasets:

$ python ./image-scripts/run-cub.py       #CUB
$ python ./image-scripts/run-sun.py       #SUN
$ python ./image-scripts/run-flo.py       #FLO
$ python ./image-scripts/run-awa1.py      #AWA1
$ python ./image-scripts/run-awa2.py      #AWA2

Note: All of above results are run on a server with one GPU (Nvidia 1080Ti).
