The Core Idea

Deep learning relies on representing data across layered feature spaces.

These layers allow the system to learn increasingly complex patterns from raw input.

Neural Networks - The Building Blocks

At its heart, deep learning uses artificial neural networks – inspired by the human brain.

These networks consist of interconnected nodes that process information and adjust their connections based on training data.

Training the Network

The network learns through a process called ‘training,’ where it’s fed with large amounts of data.

It then adjusts its internal parameters – known as weights – to minimize errors and improve accuracy.

Frequently asked questions

What is deep learning?

Deep learning is a family of machine learning methods that use multi-layer neural networks.

What are neural networks?

Neural networks are computational models inspired by the structure and function of biological neurons, designed to recognize patterns in data.

How does training a neural network work?

Training involves feeding the network labeled data and adjusting its internal parameters – weights – to minimize the difference between predicted outputs and actual values.
