Abstract:
The SVM needs to use approximation accuracy Ε, however the LS-SVM doesn't need Ε. According to this characteristics, the paper studied the fitting and generalization capabilities of models that LS-SVM and SVM established for the penicillin fermentation process respectively. An improved GA selected the parameter values for LS-SVM and SVM respectively. The experiment shows that the model based on LS-SVM possesses the strong capabilities of fitting and generalization. If Ε is too large, the capabilities of fitting and generalization of model based on SVM are not high; if Ε is too small, the capabilities of fitting and generalization are relatively high, but the modeling process demands long time. Therfore, the LS-SVM is more suitable for modeling in fermentation processes.
