UnverifiedFinite-sample estimation of entropy rate faces a systematic negative bias problem, where plug-in estimators tend to underestimate the true entropy; this can be compensated using the Miller-Madow correction by adding a (k-1)/(2N) term.71% similarUnverifiedThe entropy rate is defined as H(X) = lim (1/n) H(X_1,...,X_n), representing the average amount of information carried per symbol.71% similarUnverifiedAssuming the data follows a Bernoulli or multinomial distribution, maximizing the likelihood is equivalent to minimizing the cross-entropy loss function.68% similarUnverifiedBecause H(p) is a model-independent constant, minimizing cross-entropy is equivalent to minimizing KL divergence; this equivalence is mathematically exact.68% similarVerifiedThe cross-entropy loss in classification tasks is essentially the negative of the log-likelihood function, and minimizing cross-entropy is equivalent to maximizing the log-likelihood of the model on the training data.67% similar
