Cost function is the calculation of the error between … WebOct 9, 2016 · The typical cost functions you encounter (cross entropy, absolute loss, least squares) are designed to be convex. However, the convexity of the problem depends also on the type of ML algorithm you use. Linear algorithms (linear regression, logistic regression etc) will give you convex solutions, that is they will converge.
