An IDS detection algorithm based IBP neural network

This paper discuss limitation of multi-ply feedback neural network algorithm, put forward a fast IDS detection algorithm based improved BP algorithm -IBP, new algorithm add a momentum item adopt alterable learn speed policy and batching, simulation with computer proves that choose bigger learning gene can quicken algorithm convergent speed. The modified algorithm has some advantage than traditional algorithm in convergent speed, susceptive to begin coefficient, stabilization in network.
