What is Neural Network?
A neural network is a machine-learning model loosely inspired by the brain, made of layered 'neurons' that learn to recognise patterns in data.
Neural networks power today's AI — from image recognition to the large language models behind chat assistants.
kenai keeps the theory light and the practice heavy: you don't need to build neural networks to use AI productively at work.
