一种改进的SVM算法在乳腺癌诊断方面的应用
Application of an improved support vector machine algorithm in the diagnosis of breast cancer
摘要
Abstract
To optimize the accuracy of computer aided diagnosis (CAD) technology in the diagnosis of breast cancer,we propose a new support vector machine algorithm based on the feature weighting of Gini index under the random forest model (RFG-SVM).The algorithm uses the Gini index under the random forest model to measure the impact of each feature on the classification results,and to build a support vector machine with the weighted feature vector kernel function,which is then applied to the diagnosis of breast cancer.Theoretical analysis and experimental data tests show that the proposed algorithm has higher classification accuracy than the traditional SVM and is more competitive than the stateof-the-art methods in medical diagnostics.关键词
