Binary cross entropy loss function in python
WebIn this Section we describe a fundamental framework for linear two-class classification called logistic regression, in particular employing the Cross Entropy cost function. Logistic regression follows naturally from the regression framework regression introduced in the previous Chapter, with the added consideration that the data output is now constrained …
