Calculating Cross Entropy in TensorFlow

Web15 Mar 2024 · Cross entropy loss is often considered interchangeable with logistic loss (or log loss, and sometimes referred to as binary cross entropy loss) but this isn't always correct. Cross entropy loss measures the difference between the discovered probability distribution of a machine learning classification model and the predicted distribution. Web15 Jul 2024 · The other way of implementing the categorical cross entropy loss in TensorFlow is using a label-encoded representation for the class, where the class is represented by a single non-negative integer indicating the ground truth class instead. harry potter digital audio books
