Class LambdaMARTGridSearch<U>

java.lang.Object
es.uam.eps.ir.relison.grid.links.recommendation.algorithms.supervised.LambdaMARTGridSearch<U>
Type Parameters:
U - type of the users.
All Implemented Interfaces:
AlgorithmGridSearch<U>
public class LambdaMARTGridSearch<U>
extends java.lang.Object
implements AlgorithmGridSearch<U>
Grid search generator for LambdaMART algorithm. Differently from other algorithms, for the LambdaMART algorithm, we consider the grid to be a list of configurations.
