Install Learn Introduction TensorFlow Lite for mobile and edge devices For Production TensorFlow Extended for end-to-end ML components API 5/6/ · We start with the binary one, subsequently proceed with categorical crossentropy and finally discuss how both are different from e. hinge loss. Well, what you need to know first 16/8/ · In Keras by default we use activation sigmoid on the output layer and then use the keras binary_crossentropy loss function, independent of the backend implementation 26/4/ · This means that you’re taking on more risk than you’ll earn. A binary option that is a winner will guarantee an 81 percent return. A cash-out option will pay nothing. Some binary ... read more

Improve this answer. answered Dec 13, at Maxim Maxim Theano doesn't actually force you to use the wrong implementation of cross-entropy. It's purely a Keras design decision. Frameworks based on Theano that pre-dated Keras actually got it right.

See for example the pylearn2 implementation: github. I had to add a comment here. I just could not believe when I saw IanGoodfellow! The Godfather, the Creator of GANs himself!

Jul 21, · Binary crossentropy between an output tensor and a target tensor. Jul 28, · class BinaryCrossentropy: Computes the cross-entropy loss between true labels and predicted labels.

class CategoricalCrossentropy: Computes the crossentropy loss between the labels and predictions. class MeanSquaredError: Computes the mean of squares of errors between labels and predictions. Main aliases tf.

Use this cross-entropy loss when there are only two label classes assumed to be 0 and 1. For each example, there should be a single floating-point value per prediction. Usage with the tf. When 0, no smoothing occurs. Reduction to apply to loss. Default value is AUTO. AUTO indicates that the reduction option will be determined by the usage context.
