Phenomenon-Graph JEPA: Label-Efficient Representation Learning for Contactless Cardiorespiratory Sensing
Constantino Álvarez Casado, Nhi Nguyen, Mohammad Rakibur Rahman +4
Millimeter-wave (mmWave) radar and RGB-D cameras can record cardiac and respiratory waveforms continuously and without contact, but labeled recordings remain scarce because every l…
Handwritten Digit Leakage from Smartphone Motion Sensors Across Unseen Users and Phone Models
Constantino Álvarez Casado, Erkka Rantahalvari, Matteo Pedone +6
Smartphone motion sensors support interactive applications, but their readings may also reveal touchscreen input beyond their intended use. Assuming known drawing intervals, we stu…
From Theory to Throughput: CUDA-Optimized APML for Large-Batch 3D Learning
Sasan Sharifipour, Constantino Álvarez Casado, Manuel Lage Cañellas +1
Loss functions are fundamental to learning accurate 3D point cloud models, yet common choices trade geometric fidelity for computational cost. Chamfer Distance is efficient but per…
Multi-objective Feature Selection in Remote Health Monitoring Applications
Le Ngu Nguyen, Constantino Álvarez Casado, Manuel Lage Cañellas +4
Radio frequency (RF) signals have facilitated the development of non-contact human monitoring tasks, such as vital signs measurement, activity recognition, and user identification.…
