文脈
ミリオンソングデータセット（MSD）は、100万曲の現代的な流行音楽トラックの音声特徴量とメタデータの無料で利用可能なコレクションです。これはMSDのサブセットであり、曲の年次情報を含む曲の音声特徴量を収録しています。目的は、音声特徴量から曲のリリース年を予測することです。
内容
所有者は、与えられたアーティストの曲がトレーニングセットとテストセットの両方に含まれないようにすることで「プロデューサー効果」を避けるため、データを次のように分割することを推奨しています。
- トレーニング：最初の463,715件の例
- テスト：最後の51,630件の例
フィールドの説明：
- 最初の値は年（ターゲット）で、1922年から2011年までの範囲です。
- その後に90個の属性があります。
- 音色平均[1 - 12]
- 音色共分散[1 - 78]
これらの特徴量は、The Echo Nest APIの「音色」特徴量から抽出されました。著者は、すべての「セグメント」にわたって平均と共分散を求め、各セグメントは12次元の音色ベクトルで記述されました。
