関数の入力パラメータと学習パラメータ
第1 章では、関数の入力パラメータ
と出力
の関係を整理しましたが、ここ
で新しいパラメータとしてフィッティングパラメータが出てきました。この
フィッティングパラメータは、関数のパラメータですが、
とは異なりますの
で、
で表し、関数
と書いて、
とは異なるパラメータであることがよ
く明示されます。それぞれ、
：入力パラメータ、入力、説明変数など
： 学習パラメータ、フィッティングパラメータ、モデルパラメータ、重み
など
と呼ばれますが、本書では以降、特別な場合を除いて、
を入力パラメータも

学習の予測時は入力パラメータが予測の条件パラメータになります。このよ
うに、実際の機械学習応用では、頻繁に最適化や予測のパラメータが切り替
わりますので、今行っている作業（学習、予測、サロゲート最適化など）で
は何がパラメータとなっているかを意識することが大切です。
