Detailed Description

Scoring metric that aims to minimize the score value.

This class implements a scoring metric where lower values indicate better performance (e.g., MSE, MAE, deviance). It overrides the base Score class comparison methods to establish that higher values are worse.

Member Function Documentation

initValue()

double slope::MinimizeScore::initValue ( ) const

overridevirtual

Returns the initial value for minimization metrics.

Returns

Positive infinity as the worst possible score

Implements slope::Score.

isWorse()

bool slope::MinimizeScore::isWorse ( double  a, double  b  ) const

overridevirtual

Determines if score a is worse than score b.

Parameters

a	First score to compare
b	Second score to compare

Returns

true if a > b (higher values are worse)

Implements slope::Score.
