Device Passport: Enabling Spatio-Temporal Pretrained Models to Generalize Across Input Layouts

Geeling Chau, Ran Liu, Juri Minxha +5

New device layouts pose a challenging modeling problem due to the lack of large datasets for each specific layout. Biosignal foundation models offer a plausible solution if they ar…

Multimodal Emotion Regression with Multi-Objective Optimization and VAD-Aware Audio Modeling for the 10th ABAW EMI Track

Jiawen Huang, Chenxi Huang, Zhuofan Wen +7

We participated in the 10th ABAW Challenge, focusing on the Emotional Mimicry Intensity (EMI) Estimation track on the Hume-Vidmimic2 dataset. This task aims to predict six continuo…

CPEP: Contrastive Pose-EMG Pre-training Enhances Gesture Generalization on EMG Signals

Wenhui Cui, Christopher Sandino, Hadi Pouransari +7

Hand gesture classification using high-quality structured data such as videos, images, and hand skeletons is a well-explored problem in computer vision. Leveraging low-power, cost-…

Generalizable autoregressive modeling of time series through functional narratives

Ran Liu, Wenrui Ma, Ellen Zippi +8

Time series data are inherently functions of time, yet current transformers often learn time series by modeling them as mere concatenations of time periods, overlooking their funct…

Model-driven Heart Rate Estimation and Heart Murmur Detection based on Phonocardiogram

Jingping Nie, Ran Liu, Behrooz Mahasseni +2

Acoustic signals are crucial for health monitoring, particularly heart sounds which provide essential data like heart rate and detect cardiac anomalies such as murmurs. This study…
