    Feature Selection Based on Hybridization of Genetic Algorithm and Particle Swarm Optimization 
    Ghamisi, Pedram; Benediktsson, Jon Atli (IEEE Geoscience & Remote Sensing Society, 2015-02)
    A new feature selection approach that is based on the integration of a genetic algorithm and particle swarm optimization is proposed. The overall accuracy of a support vector machine classifier on validation samples is used as a fitness value. The new ...
