[0132] Example: awAPInt(i 1 ,i 2 )=|(5×1.47–3.18×0.61) / (5×1.47+3.18×0.61)|=|5.41 / 9.29|=0.58, awAPInt(i 1 , “i 2 )=|5.41 / (9.29–2×5×3.18)|=0.24, awAPInt(‘i 1 ,i 2 )=|5.41 / (9.29–2×5×0.61)|=1.69, awAPInt(‘i 1 , “i 2 )=|5.41 / (9.29+2×5×(5–3.18–0.61))|=0.25.
[0133] Definition 5
[0134] Mutual information of fully weighted itemset: all-weighted Mutual Information of Itemset, referred to as awMI: mutual information (Mutual Information) is a common method for computational linguistics model analysis, which measures the degree of correlation between two objects x and y, refers to is the logarithm of the ratio of the posterior probability p(x|y) of x to the prior probability p(x) (Fu Zuyun. Basic Theory and Application of Information Theory (Third Edition). Electronic Industry Press, 2011.2, ISBN9787121129001.), if The value of mutual information is greater than 0, indicating that x and y are positively correlated, otherwise, if the value is less than 0, it is negatively correl...
