WebComputes the cross-entropy loss between true labels and predicted labels. WebFor binary classification it is defined as H ( p, q) = − y log ( p) − ( 1 − y) log ( 1 − p). Let's assume that the real class of the above example is 0, y = 0. Then we made a mistake and you can see that H ( p, q) = − 0 log ( 0.26894142) − ( 1 − 0) log ( 1 − 0.26894142) = 0.313. That is the loss that is used for backpropagation. Share
