Supervised Machine Learning Classification An In Depth

Jul 17, 2019·Machine learningis the science (and art) of programming computers so they can learn from data. [Machine learningis the] field of study that gives computers the ability to learn without being explicitly programmed. — Arthur Samuel, 1959. A betterdefinition:

Statistical Classification Definition DeepAI

Statistical classificationis the broad supervisedlearningapproach that trains a program to categorize new, unlabeled information based upon its relevance to known, labeled data. The algorithms that sort unlabeled data into labeled classes, or categories of information, are calledclassifiers.
