A Grey Wolf Optimizer Feature Selection method and its Effect on the Performance of Document Classification Problem




  • ibraheem al-jadir uruk

Optimization methods are considered as one of the highly developed areas in Artificial
Intelligence (AI). The success of the Particle Swarm Optimization (PSO) and Genetic Algorithms (GA)
has encouraged researchers to develop other methods that can obtain better performance outcomes and to
be more responding to the modern needs. The Grey Wolf Optimization (GWO), and the Krill Herd (KH)
are some of those methods that showed a great success in different applications in the last few years. In this
paper, we propose a comparative study of using different optimization methods including KH and GWO
in order to solve the problem of document feature selection for the classification problem. These methods
are used to model the feature selection problem as a typical optimization method. Due to the complexity
and the non-linearity of this kind of problems, it becomes necessary to use some advanced techniques to
make the judgement of which features subset that is optimal to enhance the performance of classification
of text documents. The test results showed the superiority of GWO over the other counterparts using the
specified evaluation measures.
