摘要

QoS prediction method based on neural network is used to derive all kinds of algorithm based on the bigger sample number, and the algorithm is expected to perform better when the sample is small. However, the reality is on the contrary. When the sample quantity is limited, the neural network may show poor generalization ability. The SVM method solves the problem of over fitting, non-linear and the dimension disaster in a large part. It is the best theory of small samples statistical learning at present. This paper presents a method of situation forecast based on SVM, by using PSO to optimize SVM, finally show the effectiveness of PSO-SVM model in the small sample data through error analysis.
