Improved BP Algorithm and Its Application to Intelligent Diagnosis of Coronary Heart Disease

摘要：

BP algorithm is improved and developed by using the iteration of Levenberg-Marquardt algorithm which improves the network convergence rate. After the analysis of the coronary heart disease cases provided by Cleveland Clinic Foundation, the 14 parameters which reflect the characteristics of coronary heart disease are concluded. On the basis of the improved BP algorithm, the simulation model of intelligence diagnosis is built. With the application of this method, the diagnosis rate can reach 99.3％.

关键词： improved BP Algorithm iteration of L-M weight intelligent diagnosis.
