An Experimental Comparison of Genetic Algorithms for Optimizing Support Vector Regression in Grid Resources Prediction
In order to manage the grid resources more effectively,the prediction information of grid resources is necessary in the grid system, In this study, support vector regression (SVR) is applied to grid resources prediction, In order to build an effective SVR model, SVRs parameters must be selected carefully. Therefore, we develop a genetic algorithmbased SVR (GA-SVR) model that can automatically determine the optimal parameters of SVR with higher predictive accuracy and generalization ability simultaneously. In this study, binary-coded GA (BGA), real-coded GA with heuristic crossover and uniform mutation (HRGA) and real-coded GA with simulated binary crossover and polynomial mutation (SRGA) are compared for SVRs parameters optimization with grid resources benchmark data set. Experimental results demonstrate that the hybrid model SRGA-SVR works better than BGA-SVR and HRGA SVR.
