Web2 Answers. You could try shuffling your data to make it independent, and use the same procedure to compute the MI score. This would provide a surrogate for the null hypothesis, and if you are okay with p-values, perhaps you can choose a threshold by selecting something like p-value of 0.05. Computing Normalized Mutual Information will put the ... 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 …
WebLet X n be a memoryless uniform Bernoulli source and Y n be the output of it through a binary symmetric channel. Courtade and Kumar conjectured that the Boolean function f : { 0 , 1 } n → { 0 , 1 } that maximizes the mutual information I ( f ( X n ) ; Y n ) is a dictator function, i.e., f ( x n ) = x i for some i. We propose a clustering problem, which is … Web8 de jan. de 2016 · The type of Normalize Mutual Information implemented in this class is given by the equation \[ \frac{ H(A) + H(B) }{ H(A,B) } \] ...

Web9 de mar. de 2015 · From Wikipedia entry on pointwise mutual information:. Pointwise mutual information can be normalized between [-1,+1] resulting in -1 (in the limit) for never occurring together, 0 for independence, and +1 for complete co-occurrence. Web16 de nov. de 2024 · Thus, the new mutual information theory-based approach, as shown in Equations 1, 3 and 4, could verify both the comprehensive performance of all categories of forecast and the forecast performance for a certain category and establish the linkage between these two parts in deterministic multi-category forecasts.
