چکیده
Microarray data have an important role in identification and classification of the cancer tissues. Having a few samples of microarrays in cancer researches is always one of the most concerns which lead to some problems in designing the classifiers. Therefore, gene selection techniques should be utilized before classification to remove the non-informative genes from the microarray data. In this paper, a new method is proposed for gene selection based on hybrid Binary Particle Swarm Optimization (BPSO) and Bayesian Linear Discriminant Analysis (BLDA) in order to classify a large scale of microarray data. The proposed algorithm is applied on four cancer datasets and its results are compared with other existing methods. The results illustrate that the proposed algorithm has higher accuracy and validity in comparison to other existing methods and is able to select the small subset of informative genes in order to increase the classification accuracy.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
