In this paper we deal with the problem of feature selection by introducing a new approach based on Gravitational Search Algorithm (GSA). The proposed algorithm combines optimization behavior GSA together speed Optimum-Path Forest (OPF) classifier in order to provide fast and accurate framework for selection. Experiments datasets obtained from wide range applications, such as vowel recognition, image classification fraud detection power distribution systems are conducted asses robustness...
