WebIn statistics, probability theory and information theory, pointwise mutual information ( PMI ), [1] 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. [2] WebPointwise label and Pairwise label are both widely used in computer vision tasks. For example, supervised image classification and annotation approaches use pointwise label, while attribute-based image relative learning often adopts pairwise labels. These two types of labels are often considered independently and most existing efforts utilize ...
