Out-of-Distribution Detection for Generalized Zero-Shot Action Recognition

Overview

This repository is the PyTorch implementation for the paper Out-of-Distribution Detection for Generalized Zero-Shot Action Recognition, published at CVPR 2019. This repo is based on the codebase of f-CLSWGAN, which was originally proposed for zero-shot object classification.

Dependencies

PyTorch 0.3.1
Python 3.5

Features

The I3D features (concatenated RGB and Flow) for HMDB51 and UCF101 are provided here. Place the unzipped sub-folders under data_action folder before running the experiments.

Running

Shell scripts for running the baseline ZSL/GZSL/GZSL-OD experiments on HMDB51 and UCF101 datasets are provided.
