Description
なお、上記で括弧内に記した参照符号は、後述する実施形態における対応する構成要素の符号を参考のために例示したものである。
ここで、
x:入力データベクトル
w:パラメータベクトル
LOG:クラスの事後確率
であるとする。xは、電流積算値、モータ駆動電圧の2次元ベクトル、LOGは、油温が閾値以上(もしくは以下)である確率となる。
と表現できる。同じクラス内でも時間経過により油温が変化することが考えられるため、ここではx1およびx2に条件付き独立の仮定をおいた。
次に、x1に対するロジスティック回帰の出力をLOG1とおき、それをベイズの定理に従い、以下のように変形する。
となる。事前確率であるp(y=1)およびp(y=0)に関する情報は得られないため、ここではp(y=1)=p(y=0)とした。(数7)を(数5)に代入することで、x1,x2が与えられた場合の事後確率は、以下の(数8)で表すことができる。
仮に、現在N回の出力があり、全ての出力が通常の閾値を超えているとすると、上記(数11)の右辺である「通常の閾値と等しい出力がN回なされた場合の事後確率」がこのN回目で高い閾値を超えたのであれば、N回目において左辺である「複数回の出力から計算した事後確率」も必ず高い閾値を超えていることになる。
