Using binary_crossentropy loss in Keras (Tensorflow backend)

Question

In the training example in Keras documentation,

https://keras.io/getting-started/sequential-model-guide/#training

binary_crossentropy is use

Answer 1

In categorical cross entropy :

• if it is prediction it will compute the cross entropy directly
• if it is logit it will apply softmax_cross entropy with logit

In Binary cross entropy:

• if it is prediction it will convert it back to logit then apply sigmoied cross entropy with logit
• if it is logit it will apply sigmoied cross entropy with logitdirectly
