3. 3/22 Introduction What is “cover songs identification”?

4. 4/22 Introduction (Cont’d) Another example:

5. 5/22 Introduction (Cont’d) Definition : In popular music, a cover version or cover song, or simply cover, is a new performance or recording of a previously recorded, commercially released song by someone other than the original artist or composer Issues: In different cover versions, there exists different Language Background (Companion) Music Singer Tones Etc.

11. 11/22 Surveys (Cont’d) Evaluation metrics: Mean Average Precision (MAP) Mean averaged Reciprocal Rank (MaRR) aRR1 = (1+1/3+1/6+1/9+1/10)/5 = 0.342 aRR2 = (1/2+1/5+1/7)/3 = 0.281 MaRR = (0.342+0.281)/2 = 0.312

12. 12/22 Surveys (Cont’d) Evaluation Results: 2125 songs include 523 version sets (Avg. 4 songs/version) 76 songs for parameter training (subset of 2125 songs)
