R的Amore包中实现BP神经网络初始化的函数为newff，而newff中并没有初始权值和阈值的设置，针对这个问题，我邮件询问了该包的作者，以下是问题和来来自作者的答复，供大家参考。
Question：
Hi,
I was wondering that where are the settings of [backcolor=rgba(0, 0, 0, 0)]weights and biases initiation in BP Neural Networkwhen we created a BP with Amore package? I have searched related functions like newff and train.
Hope for your reply soon.

Hi!They are initiated using random values following a strategy described in Haykin's book.
Browsing the source might give you also the details.
