What Machine Learning actually is?
Machine Learning is a field of statistics and computer science that gives computer systems the ability to “learn”, or better yet, to progressively improve performance on a specific task, leveraging data, without being explicitly programmed.
The term was first used in 1959 (yep, that long!), it evolved from a study of pattern recognition and computational learning theory in artificial intelligence. Machine Learning explores the study and construction of algorithms that can learn from and make predictions on data – such algorithms overcome following strictly static program instructions by making data-driven predictions or decisions.
Nowadays, the most common form of Machine Learning is through the use of Neural Networks.
