Cross entropy loss function equation
WebJul 10, 2024 · Bottom line: In layman terms, one could think of cross-entropy as the distance between two probability distributions in terms of the amount of information (bits) … WebApr 10, 2024 · The closer the two are, the smaller the cross-entropy is. In the experiments, the cross-entropy loss function is first used to evaluate the effect of each sub module in the LFDNN and then the total loss function evaluation value is calculated through the Fusion layer. The LFDNN achieves the best results for both of the two datasets, too.
