Normalized mutual information equation
Web20 de fev. de 2024 · So, the harnomic mean between the entropies would give us a tighter upper bound on the mutual information. I was wondering whether there is a specific reason why the geometric and arithmetic means are preferred for normalizing the mutual information. Any suggestions would help. Thanks!

Webwhere, again, the second equation is based on maximum likelihood estimates of the probabilities. in Equation 184 measures the amount of information by which our … In statistics, probability theory and information theory, pointwise mutual information (PMI), or point mutual information, is a measure of association. It compares the probability of two events occurring together to what this probability would be if the events were independent. PMI (especially in its positive pointwise mutual information variant) has been described as "one of the most important concepts in NLP", where it "draws on the intuition that the best way to weigh …
