what is the definition of entropy? why use information entropy how can the entropy of a model be used for analyzing model quality? why do we use information entropy in our model? why can we use entropy to measure quality of a language model why is entropy used in language modeling why use entropy? if a language designer makes an experiment, what is the entropy when do we use entropy? why can we use information entropy if entropy is a function of language model why are language models important? why do we use entropy when we model language how to determine entropy of a model entropy vs entropy definition why can we use entropy how entropy is used to determine the model quality why can we use entropy to measure a model? why use entropy how to use entropy and entropy in language
