[AI-NN-PR] A-hybrid-least-squares DL : 0: A hybrid least squares support vector machines and GMDH approach for river ﬂ ow forecasting-This paper proposes a novel hybrid forecasting model, which combines the group method of data handling (GMDH) and the least squares support vector machine (LSSVM), known as GLSSVM. The GMDH is used to determine the useful input vari- ables for LSSVM model and the LSSVM model which works as time series forecasting. 5 In this study the application of GLSSVM for monthly river ﬂ ow forecasting of Selangor and Bernam River are investigated. The results of the proposed GLSSVM approach are compared with the conventional artiﬁ cial neural network (ANN) models, Autoregres- sive Integrated Moving Average (ARIMA) model, GMDH and LSSVM models using the long term observations of monthly river ﬂ ow discharge. The standard statistical, the 10 root mean square error (RMSE) and coe ﬃ cient of correlation (R) are employed to eval- uate the performance of various models developed. Experiment result indicates that the hybrid model was powerful tools to mo

[matlab] Least-Squares DL : 0: 最小二乘法是系统辨识中最经典的方法，它通过最小化误差的平方和寻找数据的最佳函数匹配。利用最小二乘法可以简便地求得未知的数据，并使得这些求得的数据与实际数据之间误差的平方和为最小。最小二乘法还可用于曲线拟合。其他一些优化问题也可通过最小化能量或最大化熵用最小二乘法来表达。其中，RLS是递推最小二乘法程序，ELS是增广递推最小二乘法的程序。- System identification least squares method is the most classic method, which matches the data by squaring and finding the best to minimize the error function. Least squares method can be easily calculated unknown data, and make the square error between the actual data and the data obtained and the minimum. Least squares method can be used for curve fitting. Some other optimization problems can be expressed using the method of least squares by minimizing energy or maximizing entropy. Wherein, RLS is a recursive least squares program, ELS is augmented recursive least squares method procedures.
