Universal EEG Epilepsy Detection via Evidential Multi-View De-Biasing

AAAI 2026technical

Epilepsy is a widespread neurological disorder characterized by highly patient-specific EEG patterns. Existing EEG-based seizure detection methods either train individualized models for each patient or adapt models pre-trained on known patients to new ones. However, when encountering previously unse

Emergence of Shape Bias in Convolutional Neural Networks through Activation Sparsity

NeurIPS 2023oral

Current deep-learning models for object recognition are known to be heavily biased toward texture. In contrast, human visual systems are known to be biased toward shape and structure. What could be the design principles in human visual systems that led to this difference? How could we introduce more…

Model-Aware Contrastive Learning: Towards Escaping the Dilemmas

ICML 2023poster

Contrastive learning (CL) continuously achieves significant breakthroughs across multiple domains. However, the most common InfoNCE-based methods suffer from some dilemmas, such as uniformity-tolerance dilemma (UTD) and gradient reduction, both of which are related to a $\mathcal{P}_{ij}$ term. It h…
