Evolutionary Design of Nearest Prototype Classifiers
In pattern classification problems, many works have been carried out with the aim of designing good classifiers from different perspectives. These works achieve very good results in many domains. However, in general they are very dependent on some crucial parameters involved in the design. These parameters have to be found by a trial and error process or by some automatic methods, like heuristi...
متن کاملSome Notes on Twenty One (21) Nearest Prototype Classifiers
Comparisons made in two studies of 21 methods for finding prototypes upon which to base the nearest prototype classifier are discussed. The criteria used to compare the methods are by whether they: (i) select or extract point prototypes; (ii) employ preor post-supervision; and (iii) specify the number of prototypes a priori, or obtain this number “automatically”. Numerical experiments with 5 da...
متن کاملA Cluster-Based Merging Strategy for Nearest Prototype Classifiers
A generalized prototype-based learning scheme founded on hierarchical clustering is proposed. The basic idea is to obtain a condensed nearest neighbor classification rule by replacing a group of prototypes by a representative while approximately keeping their original classification power. The algorithm improves and generalizes previous works by explicitly introducing the concept of cluster and...
متن کاملDesign of Nearest Neighbor Classifiers Using an Intelligent Multi-objective Evolutionary Algorithm
The goal of designing optimal nearest neighbor classifiers is to maximize classification accuracy while minimizing the sizes of both reference and feature sets. A usual way is to adaptively weight the three objectives as an objective function and then use a single-objective optimization method for achieving this goal. This paper proposes a multi-objective approach to cope with the weight tuning...
