WebMSE or cross entropy. Thus often in machine learning tasks, there are actually two cost functions: the desired cost, and the one used in the optimization process. For brevity we will call the former the ‘target’ cost, and the latter the ‘optimization’ cost. The optimization cost plays two roles: it is chosen
