Description
は全体における特徴分散のベクトル(例えば、特徴1に関するジャンル11及び13の特徴値における分散、並びに特徴2に関するジャンル11及び13の特徴値の分散を含む、共分散行列Cの対角(diagonal):図2参照)であり、ここで
はジャンル毎の平均特徴値の分散のベクトル(例えば、特徴1に関するジャンル11の平均特徴値15及びジャンル13に関する平均特徴値17の間における分散、並びに特徴2に関するジャンル11の平均特徴値15及びジャンル13に関する平均特徴値17の間における分散を含む:図2参照)である。この同種の計算は、音楽アーティスト、音楽ムード、又は音楽ジャンルの代わりに個人音楽分類に関して実行され得る。この場合、各分散は、類似性の異なる次元における距離を計算する。
