KNNRegQualityEvalAlg

This class is a child of RegQualityEvalAlg. It contains the procedure for the estimation of new states using the algorithm K-Nearest Neighbors for Regression.

Name: expected type	Default value	Description
__k: int	-	The number of nearest neighbors when executing KNN.

Functions

__calc_quality(state: PlayerState): decimal 

Description

Computes the quality of a player state, between 0 and 1. A higher value means better quality.

__dist_sort(elem: PlayerState): decimal

Description

Comparer to sort a list by the Euclidean distance between the profiles of player states.

This class overrides evaluate (see QualityEvalAlg).
