Neda Damya; Farhad Soleimanian Gharehchopogh

Articles in Press, Accepted Manuscript, Available Online from 16 November 2020

Abstract
  Clustering is a method of data analysis and one of the important methods in data mining that has been considered by researchers in many fields as well as in many disciplines. In this paper, we propose combining WOA with BA for data clustering. To assess the efficiency of the proposed method, it has been ...  Read More

2. An Improved Bat Algorithm with Grey Wolf Optimizer for Solving Continuous Optimization Problems

narges jafari; Farhad Soleimanian Gharehchopogh

Volume 6, Issue 3 , Summer 2020, , Pages 119-130

Abstract
  Metaheuristic algorithms are used to solve NP-hard optimization problems. These algorithms have two main components, i.e. exploration and exploitation, and try to strike a balance between exploration and exploitation to achieve the best possible near-optimal solution. The bat algorithm is one of the ...  Read More

3. An Optimization K-Modes Clustering Algorithm with Elephant Herding Optimization Algorithm for Crime Clustering

Farhad Soleimanian Gharehchopogh; Sevda Haggi

Volume 6, Issue 2 , Spring 2020, , Pages 79-90

Abstract
  The detection and prevention of crime, in the past few decades, required several years of research and analysis. However, today, thanks to smart systems based on data mining techniques, it is possible to detect and prevent crime in a considerably less time. Classification and clustering-based smart techniques ...  Read More

6. A New Approach for Text Documents Classification with Invasive Weed Optimization and Naive Bayes Classifier

Saman Khalandi; Farhad Soleimanian Gharehchopogh

Volume 4, Issue 3 , Summer 2018, , Pages 167-184

Abstract
  With the fast increase of the documents, using Text Document Classification (TDC) methods has become a crucial matter. This paper presented a hybrid model of Invasive Weed Optimization (IWO) and Naive Bayes (NB) classifier (IWO-NB) for Feature Selection (FS) in order to reduce the big size of features ...  Read More
