Master's Thesis

Data Reliability in EEG-based Emotion Recognition: A Framework for Unreliable Data Pair Removal
Affective AI Lab | Advisor: Byung Hyung Kim

Proposed a data cleansing framework that identifies and removes unreliable EEG-label pairs โ€” samples where the correlation between EEG signals and emotion labels is degraded โ€” using deep learning-based Out-of-Distribution (OOD) detection. Achieved up to +6.14% improvement in classification accuracy and +4.33% in AUROC over the conventional method (Riemannian Potato) across three public datasets.
