چکیده
In the paper,wavelet-based adaptive support vector machine is applied to stock exchange index prediction,and Morlet wavelet function can be used as kernel function of adaptive support vector regression model. In the study, the proposed wavelet-based adaptive support vector regression models trained by the training sample sets with 2 ̃6 -dimensional input vector respectively are used to show the superiority of the wavelet-based adaptive support vector regression model compared with adaptive support vector regression model.The comparison of the prediction effects for stock exchange index between WASVR and ASVR trained by 2 ̃6-dimensional input vector respectively show that the proposed wavelet-based adaptive support vector regression algorithm is better than adaptive support vector regression algorithm in the stock exchange index prediction.

Prediction of soil cation exchange capacity using support vector regression optimized by genetic algorithm and adaptive network-based fuzzy inference system
Soil cation exchange capacity (CEC) is a parameter that represents soil fertility. Being difficult to measure, pedotransfer functions (PTFs) can be routinely applied for prediction of CEC by soil physicochemical properties that can be easily measured. This study developed the support vector regression (SVR) combined with genetic algorithm (GA) together with the adaptive network-based fuzzy infe...
