Machine learning (ML) is a field of study in artificial intelligence
concerned with the development and study of statistical algorithms that can
learn from data and generalise to unseen data, and thus perform tasks without
explicit instructions. Within a subdiscipline in machine learning, advances in
the field of deep learning have allowed neural networks, a class of
statistical algorithms, to surpass many previous machine learning approaches
in performance.
ML finds application in many fields, including natural language processing,
computer vision, speech recognition, email filtering, agriculture, and
medicine. The application of ML to business problems is known as predictive
analytics.
