Market Timing Decisions by Hybrid Machine Learning Technique: A Case Study for Dhaka Stock Market
نویسندگان
چکیده
Stock market prediction has been a challenging task due to the nature of the data which is very noisy and time varying. However, this theory has been faced by many empirical studies and a number of researchers have successfully applied machine learning approaches to predict stock market. The problem studied here is about stock prediction for the use of investors. It is true investors usually get loss because of unclear investment objective and blind investment. This paper proposes to investigate the rough set model, the artificial neural network model and the hybrid artificial neural network model and the rough set model for determining the optimal buy and sell of a share on a Dhaka stock exchange. Confusion matrix is used to evaluate the performance of the observed and 1 School of Engineering and Computer Science, Independent University, Bangladesh, Dhaka, Bangladesh. 2 School of Engineering and Computer Science, Independent University, Bangladesh, Dhaka, Bangladesh. 3 School of Engineering and Computer Science, Independent University, Bangladesh, Dhaka, Bangladesh.

Our experimental result shows that the proposed hybrid model has higher accuracy than the single rough set model and the artificial neural network model. We believe this paper will be useful to stock investors to determine the optimal buy and sell time on Dhaka Stock Exchange. Mathematics Subject Classification: 03Bxx:1, 03Cxx:1, 05Dxx:1

متن کاملAn Improved Hybrid Model with Automated Lag Selection to Forecast Stock Market
Objective: In general, financial time series such as stock indexes have nonlinear, mutable and noisy behavior. Structural and statistical models and machine learning-based models are often unable to accurately predict series with such a behavior. Accordingly, the aim of the present study is to present a new hybrid model using the advantages of the GMDH method and Non-dominated Sorting Genetic A...
