finco: FINCO Feature Selection Algorithm

Description

This function selects features using the FINCO algorithm. The dataset must contain only discretized values.

Usage

finco(data,level)

Arguments

data

Name of the dataset containing the discretized values

level

Minimum inconsistency level

Value

varselec

Index of selected features

inconsis

Inconsistency rates of the selected features

Details

The level value must be greater than the inconsistency of the whole dataset, which first must be discretized. The function inconsist included in this library computes inconsistencies. A small value for level yields a greater number of selected features.
