RANKING OF FEATURES

摘要

The invention relates to a method of computing a rank of at least one feature from a pool of features, the method comprising: obtaining (1) a plurality of feature subsets, each feature subset comprising features from the pool of features; and computing (2) the rank of the at least one feature from the pool of features on the basis of an occurrence of the at least one feature in a feature subset. For example, the rank of the at least one feature may be based on the frequency of occurrence of the at least one feature in the plurality of feature subsets. Thus, the method may be advantageously applied to rank features from the pool of features. A new subset of features comprising the top-rank features, which are potentially more useful than a subset of features from the pool of features, may be created from the computed feature ranks values. There may be many other advantageous uses for such a list of ranked features from the pool of features.
