Geo-Sign: Hyperbolic Contrastive Regularisation for Geometrically Aware Sign Language Translation

arXiv — cs.CV•Wednesday, October 29, 2025 at 4:00:00 AM
PositiveArtificial Intelligence
A new method called Geo-Sign is making waves in the field of Sign Language Translation (SLT) by focusing on the geometric properties of skeletal representations. Unlike previous approaches that mainly enhanced large language models, Geo-Sign utilizes hyperbolic geometry to better capture the hierarchical structure of sign language. This innovation could significantly improve the accuracy and effectiveness of SLT, making communication more accessible for the deaf community. It's an exciting development that highlights the importance of geometry in understanding and translating sign language.
