2008:Audio Chord Detection Results
Contents
Introduction
These are the results for the 2008 running of the Audio Chord Detection task set. For background information about this task set please refer to the Audio Chord Detection page.
Task Descriptions
Task 1 (Pretrained Systems) Goto Task 1 Results: Systems were pretrained and they were tested againts 176 beatles songs.
Task 2 (Train-Test Systems) Goto Task 2 Results: System trained on ~2/3 of the beatles dataset and tested on ~1/3. Album filtering was applied on each train-test fold such that the songs from the same album can not appear in both train and test sets simultaneously.
Overlap score was calculated as the ratio between the overlap of the ground truth and detected chords and ground truth duration. Also a secondary overlap score was calculated by ignoring the major-minor variations of the root.
Note that 4 songs were excluded from the original Beatles dataset because alignment of ground truth to the audio problems.
