Machine learning deals with software systems capable of changing in response to training data. A prominent style of architecture is known as the neural network, a form of so-called deep learning.

Neural networks are the foundation of modern machine learning and AI. They are the most essential component in understanding what AI is and how it works.

Mimicking the brain AI has become shorthand for machine learning using artificial neural networks. This technology – developed by Hopfield and Hinton – is based on the structure of the brain.
