01 / RESEARCH

Research focus

01

Graph representations and structure

Sample and electrode relationships in EEG. Semi-supervised contrastive learning and graph sparsity for classification with limited labels.

02

Multimodal learning and domain adaptation

Fusion of biosignals, speech and text. Emotion recognition under missing inputs and subject or session changes.

03

Efficient models and clinical dialogue

Compact models for motor-imagery EEG and embedded pulse inference. Retrieval, record generation and evidence verification for clinical dialogue systems.
