public interface DiscriminantCategorizer<InputType,CategoryType,DiscriminantType extends java.lang.Comparable<? super DiscriminantType>>
extends Categorizer<InputType,CategoryType>

Interface for a Categorizer that can produce a value to discriminate between how well different instances fit a given category. Thus, it can produce a pair of the category value plus a discriminant for ordering within that category.

Method Detail

evaluateWithDiscriminant

ValueDiscriminantPair<CategoryType,DiscriminantType> evaluateWithDiscriminant(InputType input)

Evaluate the categorizer on the given input to produce the expected category plus a discriminant for later producing an ordering of how well items fit into that category.

Parameters:

input - The input value to categorize with a discriminate

Returns:

A pair containing the value and the discriminant value used for ordering results belonging to the same category.
