In either case it's the stochastic part of the model; if we can pull some it into the deterministic part by adding predictors then we may well improve the fit. …

WitrynaLog loss, aka logistic loss or cross-entropy loss. This is the loss function used in (multinomial) logistic regression and extensions of it such as neural networks, defined as the negative log-likelihood of a logistic model that returns y_pred probabilities for its training data y_true . The log loss is only defined for two or more labels.
