Abstract

Zero-Shot Learning (ZSL) aims to recognise unseen object classes, which are not observed during the training phase. The existing body of works on ZSL mostly relies on pretrained visual features and lacks the explicit attribute localisation mechanism on images. In this work, we propose an attention-based model in the problem settings of ZSL to learn attributes useful for unseen class recognition. Our method uses an attention mechanism adapted from Vision Transformer to capture and learn discriminative attributes by splitting images into small patches. We conduct experiments on three popular ZSL benchmarks (i.e., AWA2, CUB and SUN) and set new state-of-the-art harmonic mean results on all the three datasets, which illustrate the effectiveness of our proposed method.

Usage:

1) Download the datasets

Follow the instructions provided in data/Dataset_Instruction.txt

2) Create a conda environment:

Refer to: Conda Environment for more information.

# conda create -n {ENVNAME} python=3.6
conda create -n ViT_ZSL python=3.6

# Activate the environment: conda activate {ENVNAME}
conda activate ViT_ZSL

3) Required libraries :

This is a PyTorch implementation

pip install -r requirements.txt 

# PyTorch
conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia

4) Train (and test) the model
