Understanding Deep Learning

Deep learning is a subset of machine learning built around artificial neural networks with multiple layers.

A basic neural transformation can be represented mathematically as:

$a=\sigma(Wx+b)$

Where:

• $x$ represents input features
• $W$ represents weights
• $b$ represents biases
• $\sigma$ represents an activation function

By stacking many layers of such transformations, deep neural networks learn hierarchical representations of data.

Unlike traditional machine learning systems that often require handcrafted features, deep learning models automatically discover complex representations from raw data.

This ability explains why deep learning became revolutionary in fields involving:

• Images
• Audio
• Language
