What is neural network?
An Artificial Neural Network is an
information processing paradigm that is inspired
by the way biological nervous systems, such as
the brain, process information.
Sigmoid neurons
The sigmoid neuron has weights for each input, w1,w2 and
overall bias, b. But the output is not 0 or 1. Instead, it's σ(w⋅x+b),
where σ is called the sigmoid function, and is defined by
