Created page with "{{see also|Machine learning terms}} ==Definition== A '''convex function''' is a type of function that has particular mathematical properties, which are especially useful in the field of machine learning. Formally, a function ''f'' : ''R^n'' → ''R'' is called convex if, for all points ''x'' and ''y'' in its domain and for any scalar ''t'' in the range of 0 ≤ ''t'' ≤ 1, the following inequality holds: f(tx + (1 - t)y) ≤ tf(x) + (1 - t)f(y) This property ensur..."
