FINAL 2007 AUDIO CLASSICAL COMPOSER IDENTIFICATION EVALUATION SCENARIO OVERVIEW

This section is put here to clarify what will happen for this year's "beta" run of the Audio Classical Composer (ACC) ID task.

  1. We will operate the ACC task as a classic train-test classification task.
  2. We will 3-fold the runs.
  3. We will hand-craft the n-fold test-train split lists.
  4. Audio files: 30 sec., 22kHz, mono, 16 bit

Do take a look at the 2007:Audio Genre Classification task wiki as we are basing the underlying structure of this task on Audio Genre. In fact, an Audio Genre submission should work out of the box with Audio Mood Classification. Note: we really want folks to do a FEATURE EXTRACTION phase first against all the files and then have these features cached some place for re-use during the TRAIN-TEST phase. This way we can really speed up the n-fold processing. Thus, like GENRE, we need to pass three input files to your algos:

1. Feature extraction list file

The list file passed for feature extraction will a simple ASCII list file. This file will contain one path per line with no header line.

2. Training list file

The list file passed for model training will be a simple ASCII list file. This file will contain one path per line, followed by a tab character and the genre label, again with no header line.

E.g. <example path and filename>\t<mood classification>

3. Test (classification) list file

The list file passed for testing classification will be a simple ASCII list file identical in format to the Feature extraction list file. This file will contain one path per line with no header line.

Classification output files

Participating algorithms should produce a simple ASCII list file identical in format to the Training list file. This file will contain one path per line, followed by a tab character and the genre label, again with no header line. E.g.:

<example path and filename>\t<composer_name>

The path to which this list file should be written must be accepted as a parameter on the command line.

Introduction

This task is intended to be a sub-task of artist identification and will be run in exactly the same format on a different database.

The task is to identify the composer of a number of pieces of classical music from the baroque, classical and romantic periods. This task is distinct from artist identification in that the performer of each piece may be varied.

Due to the fact that the submission format is likely to be identical to that of audio artist identification and genre classification - participants to either task may also enter their algorithm into this task.

Status

A provisional specification of the composer identification task is detailed below. This proposal may be refined based on feedback from the particpants.

Data

2772 30-second 22.05 kHz mono wav clips organised into 11 "classical" composers (252 clips per composer). At present the database contains tracks for:

  • Bach
  • Beethoven
  • Brahms
  • Chopin
  • Dvorak
  • Handel
  • Haydn
  • Mendelssohn
  • Mozart
  • Schubert
  • Vivaldi

Evaluation

The evaluation procedures used for artist identification will also be used for this task. Please see 2007:Audio Artist Identification for details.

Submission format

Submission to this task will have to conform to a specified format detailed in the 2007:Audio Artist Identification proposal.

Audio formats

Participating algorithms will have to read audio in the following format:

  • Sample rate: 22 KHz
  • Sample size: 16 bit
  • Number of channels: 1 (mono)
  • Encoding: WAV

Implementation details

Please see 2007:Audio Artist Identification for details.

I/O formats

Please see 2007:Audio Artist Identification for details.

Packaging submissions

Please see 2007:Audio Artist Identification for details.

Pre-trained submissions

Pre-trained submissions to this task will be accepted - however they will have to ensure that they return the correct classification labels (as listed in the hierachy file).

Time and hardware limits

Due to the potentially high number of particpants in this and other audio tasks, hard limits on the runtime of submissions will be specified.

A hard limit of 24 hours will be imposed on feature extraction times.

A hard limit of 24 hours will be imposed on each training/classificaiton cycle, leading to a total runtime limit of 72 hours.

Submission opening date

14th August 2007 - provisional

Submission closing date

28th August 2007 - provisional
