Introduction
Loss function (or cost function) is widely used for measuring the differences between predicted goal and real value. In different scenario, user should choose different loss function. This blog will introduce some markable loss function and their usage conditions and disadvantages.
Log Loss
Focal Loss
KL Divergence / Relative Entropy
Exponential Loss
Hinge Loss
