摘要
理想的初始值可以使多层前向网络模型有较快的收敛速度,同时避免陷入局部最小.对现有多种前向网络的权值初始化方法进行了综述,最后提出了若干待研究的问题.
Proposed initialization methods which are shown to achieve very fast learning speed and to decrease the probability of local minima are suggested. In this paper, the recent developments of initialization of multilayer feedforward neural networks are surveyed. Finally ,the major problems and research trends are pointed out.
