Las Vegas Filter uses a random generation of subsets and an inconsistency measure as the evaluation function to determine the relevance of features in the dataset.

data |
Name of the discretized dataset |
lambda |
Threshold for the inconsistency |
maxiter |
Maximum number of iterations |
If the dataset has continuous variables, these must first be discretized. This package includes four discretization methods. A value of lambda close to the inconsistency of the whole dataset yields a large number of selected features, a large lambda yields few selected features.
