Predicting Financial Time Series by Genetic Programming with Trigonometric Functions and High-Order Statistics
نویسندگان
چکیده
This paper describes an extension of the traditional application of Genetic Programming in the domain of the prediction of daily currency exchange rates. In combination with trigonometric operators, we introduce a new set of high-order statistical functions in a unique representation and analyze their performance using daily returns of the British Pound and Japanese Yen. In addition, the same experimental design and analysis is applied to ten other financial time series from two different domains. We will demonstrate that the introduction of high-order statistical functions in combination with trigonometric functions will outperform other traditional models such as ARMA models and Genetic Programming with the basic function set. We utilize the Akaike Information Criterion for the selection of the best ARMA model for our benchmark testing. Performance will be measured on hit percentage, average percentage change, and profit. The t-test is applied to derive confidence intervals and to evaluate the significance of our results. Program Track Evolutionary Computing, Time Series Prediction.

Bankruptcy Prediction: Dynamic Geometric Genetic Programming (DGGP) Approach
In this paper, a new Dynamic Geometric Genetic Programming (DGGP) technique is applied to empirical analysis of financial ratios and bankruptcy prediction. Financial ratios are indeed desirable for prediction of corporate bankruptcy and identification of firms’ impending failure for investors, creditors, borrowing firms, and governments. By the time, several methods have been attempted in...
متن کاملA New Dynamic Random Fuzzy DEA Model to Predict Performance of Decision Making Units
Data envelopment analysis (DEA) is a methodology for measuring the relative efficiency of decision making units (DMUs) which ‎consume the same types of inputs and producing the same types of outputs. Believing that future planning and predicting the ‎efficiency are very important for DMUs, this paper first presents a new dynamic random fuzzy DEA model (DRF-DEA) with ‎common weights (using...

It is difficult to apply the real world’s conceptions due to their uncertainty. Generally, time series are known to be non-linear or non-stationary. Regarding these two features, a system should be sensitive enough to apply the unity of time series and repeat this sensitiveness in the prediction. A predict system can exactly scrutinize the hidden features of time series and also can have high p...
