TSTAI: A Time-varying Brain Effective Connectivity Network Construction Method Combining with Brain Active Information

IJCAI 2025

More accurate construction of brain effective conncetivity networks remains a great challenge to achieve accurate auxiliary diagnosis of brain diseases and in-depth exploration of brain function. However, existing methods only consider higher-order or non-stationary assumptions, rather than simultan

Robust Sleep Staging over Incomplete Multimodal Physiological Signals via Contrastive Imagination

NeurIPS 2024poster

Multimodal physiological signals, such as EEG, EOG and EMG, provide rich and reliable physiological information for automated sleep staging (ASS). However, in the real world, the completeness of various modalities is difficult to guarantee, which seriously affects the performance of ASS based on mul…

A Dynamic Cross-Scale Transformer with Dual-Compound Representation for 3D Medical Image Segmentation

ICASSP 2023accepted

Transformer models exploit multi-head self-attention to capture long-range information. Further, window-based self-attention solves the problem of quadratic computational complexity and provides a new solution for dense prediction of 3D images. However, Transformers miss structural information due t…
