This project provides implementations for our CVPR 2021 paper Counterfactual Zero-Shot and Open-Set Visual Recognition, where we propose a counterfactual-based binary seen/unseen classifier (GCM-CF) for Zero-Shot Learning (ZSL) and Open-Set Recognition (OSR). This repo contains

• ZSL: Strong binary seen/unseen classifier that is plug-and-play with any ZSL method
• ZSL: Integrations with TF-VAEGAN, RelationNet, GDAN, CADA-VAE, LisGAN, AREN
• OSR: Complete the OSR code base on MNIST, SVHN, CIFAR10, CIFAR+10, CIFAR+50 with 5 fixed random seed
• OSR: Strong baseline (F1 score) of Softmax, OpenMax, CGDL
• OSR: Implementation of our GCM-CF
