A Strong Classifier Model for Listed Companies Financial Risk Warning

Existing measures and prediction effects for the listed companies financial risk have instability. By the research on strong classifier models, we adopt Adaboost algorithm which can improve any weak learner to strong one to solve the problems. It is integrated with support vector machine to establish the warning model and study the financial warning states of domestic listed companies. The scheme takes SVM based on linear kernel function as the component classifier of Adaboost and changes the kernel function of the component classifier during the learning process. So such integration can obviously improve the performance of classifier and obtain Ada Boost SVM classifier with stronger classification ability. The experiments demonstrate that, compared to single SVM, Ada Boost SVM makes an improvement for 70 test samples of 4% in classification, which shows better application value in the research of listed warning.
