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 … Web16 de mar. de 2016 · 1 Answer. Sorted by: 9. Your floating point data can't be used this way -- normalized_mutual_info_score is defined over clusters. The function is going to interpret every floating point value as a distinct cluster. And if you look back at the documentation, you'll see that the function throws out information about cluster labels.
