From MIREX Wiki
Revision as of 16:00, 6 August 2016 by JohanPauwels (talk | contribs) (typo fix)

Introduction

This page contains the results of the 2016 edition of the MIREX automatic chord estimation tasks. This edition was the fourth one since the reorganization of the evaluation procedure in 2013. The results can therefore be directly compared to those of the last three years. Chord labels are evaluated according to five different chord vocabularies and the segmentation is also assessed. Additional information about the used measures can be found on the page of the 2013 edition.

What’s new?

Software

All software used for the evaluation has been made open-source. The evaluation framework is described by Pauwels and Peeters (2013). The corresponding binaries and code repository can be found on GitHub and the used measures are available as presets. The raw algorithmic output provided below makes it possible to calculate the additional measures from the paper (separate results for tetrads, etc.), in addition to those presented below. More help can be found in the readme.

The statistical comparison between the different submissions is explained in Burgoyne et al. (2014). The software is available at BitBucket. It uses the detailed results provided below as input.
