Abstract:

Purpose. The issue of bankruptcy prediction and taking corresponding effect-reduction measures has become an important research topic in the field of economy. The article mainly studies the issue how to improve the support vector machine (SVM) based on prediction effect of the financial crisis early-warning model.

Methodology. In view of the improved method of the kernel function exported Riemannian geometry structure, the financial crisis early-warning system based on the support vector machine (SVM) algorithm has been developed.

Findings. The improved SVM model can effectively reduce the number of support vectors so that the model can feature better capacity for generalization, and provide a more accurate classification for unknown samples. The improved SVM model has increased the classification accuracy for the original training and testing sample set.

Originality. An actual analysis on an improved algorithm for kernel function has been conducted based on the data information, according to the zoom level of data information adjustment feature mapping, giving the expression of the algorithm of Riemann measures on the polynomial kernel function. There has been no other literature describing the related study yet.

Practical value. For the financial crisis early warning issue, provided its scale is not large, and in consideration of the enterprise’s actual interests, it is often worthwhile to pursue a better prediction effect. In this case, the application of the SVM model with an improved kernel function is a good solution.
