Core.BaseLearners.LearningAttributeWeights.PSOweightLearning

public class PSOweightLearning
extends LearningAttributeWeights

Implements a Particle Swarm Optimisation method to optimise the weight of the attributes. The optimisation of the weights is performed over the whole case base (train set) The method to calculate the fitness is the revise method which is expected to return the error of the classification
