【Abstract】 A new method of designing the classifier for intrusion detection is proposed based on neural networks,and the improved BP neural network is used which adopts LevenbergMarquardt(LM) optimized algorithm. In the algorithm, the parameter μ is selfadaptable, and the network convergence speed is high,and the problems of the conventional BP algorithm such as falling into the local minimum point easily and converging slowly are solved. The experimental result shows that the performance of the classifier for intrusion detection is favorable, the learning speed of the classifier is fast, and the rate of accurate classification is high,so it is practicable to design the classifier based on the BP neural network which adopts the LM algorithm. The network provides a precise and efficient way for implementing the classifier in intrusion detection.更多还原
