SUPPORT VECTOR MACHINE METHODS IN PATTERN RECOGNITION OF SEDIMENTARY FACIES

Aiming at the problem of pattern recognition in sedimentary facies analysis, we put forward a scheme which apply SVM to sedimentary facies recognition. Unlike traditional method try to reduce the dimension of input space(i.e. characters selection and transformation), SVM increase dimension of input space to ensure it is Linearly Separable in high dimension space. The method is feasible because it only changes inner product operation and the complexity of algorithm doesn't increase. Using SVM we needn't wasting time on character extraction but resort to the intrinsic character extraction ability which makes it more suitable in practical instance. The result of practical application indicates that the performance of SVM had superiority over RBFNN and overcome the problem of overfitting excellently.
