Categorical crossentropy is a loss function that is used in multi-class classification tasks. These are tasks where an example can only belong to one out of many possible categories, and the model must decide which one. Formally, it is designed to quantify the difference between two probability distributions. Categorical crossentropy math.

Oct 21, 2020 · Categorical cross entropy is used almost exclusively in Deep Learning problems regarding classification, yet is rarely understood. I’ve asked practitioners about this, as I was deeply curious why it was being used so frequently, and rarely had an answer that fully explained the nature of why its such an effective loss metric for training.

20.10.2019 · Cross-entropy is a measure of the difference between two probability distributions for a given random variable or set of events. You might recall that information quantifies the number of bits required to encode and transmit an event. Lower probability events have more information, higher probability events have less information.
