Why are bias nodes used in neural networks? How many you should use? In which layers you should use them: all hidden layers and the output layer?

I'm curious to know how important the bias node is for the effectiveness of modern neural networks. I can easily understand that it can be important in a shallow network with only a few input variables. However, modern neural nets such as in deep…

I've read different places that talk about bias terms in neural nets like this Importance of the bias node in neural networks But I still have trouble understanding what it is used for and how it affects the neural network. In a neural network,…

I've seen a lot of examples of neural networks where when they introduce the bias, they treat it as a node that always outputs 1, and then the nodes each have an individual weight for it, instead of each having a number that they add with the rest…
