The bias bk can apply an affine transformation to the output Uk:

Vk = uk + bk

Depending on the fact whether the bk is negative or not, the relationship between the activation potential or as called induced local field vk and the linear combiner uk, can be modified as:

Induced Bias bk > 0

local field vk

Bias bk =0

0 Bias bk <0

Linear combiner’s

Output uk

The Activation Function

The activation function which is denoted by represents the neuron’s output in terms of v – the induced local field. All of the inputs are weighted individually, added together, and finally passed in this function:

We have three types of activation functions.
