Neural network? Machine Learning? Here's all you need to know about AI

One method of AI is machine learning – programs that perform better over time and with more data input. Deep learning is among the most promising approaches to machine learning. It uses algorithms based on neural networks – a way to connect inputs and outputs based on a model of how we think the brain works – that find the best way to solve problems by themselves, as opposed to by the programmer or scientist writing them. Training is how deep learning applications are "programmed" – feeding them more input and tuning them. Inference is how they run, to perform analysis or make decisions.
