Target-Side Paraphrase Augmentation for Sign Language Translation with Large Language Models
Pedro Dal Bianco, Jean Paul Nunes Reinhold, Oscar Stanchi +3
Sign language translation (SLT) remains constrained by the limited availability of paired sign-video/text corpora and by the heavy-tailed vocabularies typical of real-world dataset…
HandCraft: Dynamic Sign Generation for Synthetic Data Augmentation
Gaston Gustavo Rios, Pedro Dal Bianco, Franco Ronchetti +4
Sign Language Recognition (SLR) models face significant performance limitations due to insufficient training data availability. In this article, we address the challenge of limited…
Bringing Balance to Hand Shape Classification: Mitigating Data Imbalance Through Generative Models
Gaston Gustavo Rios, Pedro Dal Bianco, Franco Ronchetti +4
Most sign language handshape datasets are severely limited and unbalanced, posing significant challenges to effective model training. In this paper, we explore the effectiveness of…
SignAttention: On the Interpretability of Transformer Models for Sign Language Translation
Pedro Alejandro Dal Bianco, Oscar AgustÃn Stanchi, Facundo Manuel Quiroga +2
This paper presents the first comprehensive interpretability analysis of a Transformer-based Sign Language Translation (SLT) model, focusing on the translation from video-based Gre…
