TransSLR: A Lightweight Transformer for Sign Language Recognition
Lucia Yen Wanchi, Samuel Johnny, Victor Tolulope Olufemi +2
Automated Sign Language Recognition for under-represented languages remains a largely unsolved problem. Central African Sign Language (CASL) exemplifies this gap: the only availabl…
Cross-Scale Pretraining: Enhancing Self-Supervised Learning for Low-Resolution Satellite Imagery for Semantic Segmentation
John Waithaka, Gustave Bwirayesu, Moise Busogi
Self-supervised pretraining in remote sensing is mostly done using mid-spatial resolution (MR) image datasets due to their high availability. Given the release of high-resolution (…
Towards Fair and Robust Volumetric CT Classification via KL-Regularised Group Distributionally Robust Optimisation
Samuel Johnny, Blessed Guda, Goodness Obasi +2
Automated diagnosis from chest computed tomography (CT) scans faces two persistent challenges in clinical deployment: distribution shift across acquisition sites and performance di…
Position Prediction Self-Supervised Learning for Multimodal Satellite Imagery Semantic Segmentation
John Waithaka, Moise Busogi
Semantic segmentation of satellite imagery is crucial for Earth observation applications, but remains constrained by limited labelled training data. While self-supervised pretraini…
