Outline of Final Research Achievements

We conducted data collection for individuality analysis of subjective music similarity. 27 subjects evaluated similarity for 200 pairs chosen from RWC popular music database, a widely used database in the field of music information processing. Each subject also evaluated similarity for melody, tempo/rhythm, vocals and instruments for the pairs. By analyzing collected data, it is suggested that decision boundaries between similar and dissimilar pairs vary widely between individuals. Using the collected data, we trained optimized distance function between songs (weighted Euclidean distance) for each individual. In the result, training of distance function improved similarity estimation precision for vocals. From this fact, the effect of individual optimization using weighted Euclidean distance was confirmed.
