What is Neural Network?

A model made of layers of connected units that transform input into output, loosely inspired by brain cells.

In more detail

Each connection has a weight that is adjusted during training. Stacking many layers creates a deep neural network.

Example

A network that reads pixel values and outputs "cat" or "dog".
