김대현
Integrated M.S.-Ph.D. student at NeuroAI Lab, Kwangwoon University. I study EEG emotion recognition and motor-imagery decoding, speech-text fusion and contactless physiological sensing.
01 / RESEARCH
Sample and electrode relationships in EEG. Semi-supervised contrastive learning and graph sparsity for classification with limited labels.
Fusion of biosignals, speech and text. Emotion recognition under missing inputs and subject or session changes.
Compact models for motor-imagery EEG and embedded pulse inference. Retrieval, record generation and evidence verification for clinical dialogue systems.
