BTS-rPPG: Orthogonal Butterfly Temporal Shifting for Remote Photoplethysmography
Ba-Thinh Nguyen, Thi-Duyen Ngo, Thanh-Trung Huynh +2
Remote photoplethysmography (rPPG) enables contactless physiological sensing from facial videos by analyzing subtle appearance variations induced by blood circulation. However, mod…
HOT: Harmonic-Constrained Optimal Transport for Remote Photoplethysmography Domain Adaptation
Ba-Thinh Nguyen, Thi-Duyen Ngo, Thanh-Trung Huynh +2
Remote photoplethysmography (rPPG) enables non-contact physiological measurement from facial videos; however, its practical deployment is often hindered by substantial performance…
Enhancing Multimodal Recommendations with Vision-Language Models and Information-Aware Fusion
Hai-Dang Kieu, Min Xu, Thanh Trung Huynh +1
Recent advances in multimodal recommendation (MMR) highlight the potential of integrating visual and textual content to enrich item representations. However, existing methods often…
Hypergraph Diffusion for High-Order Recommender Systems
Darnbi Sakong, Thanh Trung Huynh, Jun Jo
Recommender systems rely on Collaborative Filtering (CF) to predict user preferences by leveraging patterns in historical user-item interactions. While traditional CF methods prima…
