问题:
I'm aware of the Gradient Descent and the Back-propagation Theorem. 我知道梯度下降和反向传播定理。 What I don't get is: When is using a bias important and how do you use it? 我没有得到的是:什么时候使用偏见很重要,你如何使用它?
For example, when mapping the AND
function, when I use 2 inputs and 1 output, it does not give the correct weights, however, when I use 3 inputs (1 of which is a bias), it gives the correct weights. 例如,当映射AND
功能时,当我使用2个输入和1个输出时,它不会给出正确的权重,但是,当我使用3个输入(其中1个是偏置)时,它会给出正确的权重。
