Feature selection and sentiment analysis are two common studies that currently being conducted; consistent with the advancements in computing growing use of social media. High dimensional or large feature sets is a key issue as it can decrease accuracy classification make difficult to obtain optimal subset features. Furthermore, most reviews from media carry lot noise irrelevant information. Th...

Most of the well-established particle swarm optimization (PSO) variants do not provide alternative learning strategies when particles fail to improve their fitness during the searching process. To solve this issue, we improved the state-of-art teaching–learningbased optimization algorithm and adapted the enhanced framework into the PSO. Thus, we developed a bidirectional teaching and peer-learn...

<p>Portfolio selection is among the most challenging processes that have recently increased interest of professionals in area. The goal mean-variance portfolio to maximize expected return with minimizing risk. Markowitz model was employed solve linear problem. However, due numerous constraints and complexities, problem so critical traditional models are insufficient provide efficient solu...
