- Abstract
- The problem of feature selection is crucial for many applica- tions and has thus been studied extensively. However, most of the existing methods are designed to handle data consisting only in categorical or in real-valued features while a mix of both kinds of features is often en- countered in practice. This paper proposes an approach based on mutual information and the maximal Relevance minimal Redundancy principle to handle the case of mixed data. It combines aspects of both wrapper and filter methods and is well suited for regression problems. Experiments on artificial and real-world datasets show the interest of the methodology.
