Abstract
Conference Title: 2014 Fourth World Congress on Information and Communication Technologies (WICT) Conference Start Date: 2014, Dec. 8 Conference End Date: 2014, Dec. 11 Conference Location: Melaka, Malaysia Classification, especially in the case of a small space of features, is prone to errors. This is more important when it is costly to gain data from samples to calculate the values for futures. We study what effect limiting the space of features has on the performance of built classifiers and how the quality of classification can be improved by rejecting misclassified elements.
