Machine Learning, is a subset of Artificial Intelligence, is concerned with creating learning models that allow a computer to exhibit behaviour that would normally require a human to do. Typical applications include: computer vision, speech recognition, and intelligent robots. The learning models come in various forms, such as parametric and non-parametric and probability distributions. The emphasis is on creating these models automatically from data provided and for them to act without necessarily being explicitly programmed, for example, creating a face recognition system from a data set of facial images. In the past decade, machine learning has given society effective web search, self-driving cars, practical speech recognition, and an understanding of the human genome.
