A Friendly Introduction to Cross-Entropy for Machine Learning

WebCross-entropy can be used to define a loss function in machine learning and optimization. The true probability is the true label, and the given distribution is the predicted value of the current model. This is also known as the log loss (or logarithmic loss [3] or logistic loss ); [4] the terms "log loss" and "cross-entropy loss" are used ...

WebInspired by the symmetric KL-divergence, we propose the approach of Symmetric cross entropy Learning (SL), boosting CE symmetrically with a noise robust counterpart Reverse Cross Entropy (RCE). Our proposed SL approach simultaneously addresses both the under learning and overfitting problem of CE in the presence of noisy labels. Websymmetric cross-entropy loss that combines a new term of reverse cross entropy with traditional cross entropy via constant weights on both terms. Meta-Weight-Net (Shu et al., 2024) re-weights samples during optimizing loss function in the training process by using a multi-layer perceptron to predict the weight of each sample.
