【Abstract】 Based on the brief analysis and discussion on Back-Propegntion algorithm of multi-layered neural networks,this peper Proposes an improved learning algorithm of optimal step. This algorithm determines the step which revises the connecting data between neural units by the learning principle that the input studying sample can produce the mast limited network error. The result of experiment proves that this algorithm can accelerate the learning convergent rate effectually.更多还原
