- Multi-Label Dimensionality Reduction for Music Emotion Analysis

Music can convey and evoke powerful emotions. This amazing ability has fascinated the general public and also attracted the researchers from different fields to discover the relationship between music and emotion. Psychologists have indicated that some specific characters of rhythm, harmony, melody, and also their combinations can evoke certain kinds of emotions. Their hypotheses are based on real life experience and proved by psychological paradigms on human beings. Aiming at the same target, this project intends to design a systematic and quantitative framework, and answer three widely interested questions: 1) what are the intrinsic features embedded in music signal that essentially evoke human emotions; 2) to what extent these features influence human emotions; and 3) whether the findings from computational models are consistent with the existing research results from psychological experiments.
