2008:Audio Cover Song Identification Results

From MIREX Wiki

Still missing runtimes JSD Sept. 11 2008.

Introduction

These are the results for the 2008 running of the Audio Cover Song Identification task. For background information about this task set please refer to the 2008:Audio Cover Song Identification page.

Each system was given a collection of 1000 songs which included of 30 different classes (sets) of cover songs where each class/set was represented by 11 different versions of a particular song. Each of the 330 cover songs were used as queries and the systems were required to return 10 results for each query. Systems were evaluated on the number of the songs from the same class/set as the query that were returned in the list of 10 results for each query. Average precision, which looks at the entire per-query rank-ordered list of all songs in the collection, was the new metric introduced last year.

Friedman's Test for Significant Differences

The Friedman test was run in MATLAB against the Average Precision summary data over the 30 song groups.
Command: [c,m,h,gnames] = multcompare(stats, 'ctype', 'tukey-kramer','estimate', 'friedman', 'alpha', 0.05);

Runtimes

Where algorithms have been multi-threaded, the longest runtime is reported.

Where runtimes were not properly reported, file timestamps have been used to approximate a runtime.
