Machine is one sub-set of Artificial Intelligence. The machine takes data and “learns” for itself, applying knowledge and training from large data sets for facial recognition, speech recognition, object recognition, translation, and other tasks.
Machine Learning is the science of getting computers to learn and act like humans do, and improve their learning over time in autonomous fashion, by feeding them data and information in the form of observations and real-world interactions
Machine Learning enables a system to learn to recognize patterns on its own and make predictions as opposed to a coded software program that contains specific instructions to complete a certain objective.
Machines that learn are useful to humans because, with all of their processing power, they’re able to more quickly highlight or find patterns in big (or other) data that would have otherwise been missed by human beings.
