Abstract

Instance selection is often used in case of lazy classifiers.This paper addresses the need of instance selection in case ofneural network and decision tree classifiers and presents a novelSupervised Instance Selection (SIS) algorithm. Initially, a neuralnetwork classifier is constructed using all training instances. Thealgorithm then selects a few instances using the certainty valuesof the wrapped neural network to construct a compact classifier.Empirical study made with standard datasets shows that SIS save on70% of storage space without degrading the accuracy. It isindependent of nature of the dataset and the tool used.
