Overview

This repository provides the official implementation of our paper "SignAttention: On the Interpretability of Transformer Models for Sign Language Translation". The paper presents the first comprehensive interpretability analysis of a Transformer-based model for translating Greek Sign Language videos into glosses and text, leveraging attention mechanisms to provide insights into the model's decision-making processes.

Dependencies

The code has been written in Python (3.10) and requires PyTorch (2.0). Install the required dependencies with:

pip install -r requirements.txt

Data

We utilize the Greek Sign Language Dataset, which contains 10,290 samples of RGB videos, gloss annotations, and Greek language translations. This dataset is ideal for interpretability analysis due to its detailed gloss annotations and repetition of sentences. Download the dataset here.
