3、hine control. Support vector machine to maximize the generalization ability of learning machine, even if a limited data set obtained from the discriminant function on the independent test set will be smaller still error. Therefore, the support vector machine is usd to logging time series regression.

4、 First of all, this article introduces the theory of the time-series and the basis of support vector machine. Second, it introduces detailed information on the return of support vector machine theory and algorithm.Finally, this article in accordance with the actual geological exploration of oil will be the use of support vector machine prediction of reservoir parameters logging - porosity.The results show that high prediction accuracy of the method, a stable and efficient method.
