Keys of Deep Learning : Activation Functions

A neuron (nerve cell) is the basic building block of the nervous system. A human brain consists of billions of neurons that are interconnected to each other. They are responsible for receiving and sending signals from the brain. As seen in the below diagram, a typical neuron consists of the three main parts -- dendrites, an axon, and cell body or soma. Dendrites are tree-like branches originating from the cell body.
