This python code estimates conditional mutual information (CMI) and mutual information (MI) for discrete and/or continuous variables using a nearest neighbors approach. The background and theory can be found onarXiv. Getting started Once inside the git repository directory, use the package managerpi...

Describe what you changed in the Python code above to take into account context distribution smoothing. Hint: in class CoOccurrences, two variables, unifreq1 and unifreq2 are used. Question 2. Describe what you changed in the Python code above to take into account shifted PPMI. Hint: look ...
Formally, the mutual information can be written as: I(X;Y) = E[log(p(x,y)) - log(p(x)) - log(p(y))] where the expectation is taken over the joint distribution of X and Y. Here p(x,y) is the joint probability density function of X and Y, p(x) and p(y) are the ...
Mutual Information,互信息; 互信息,刻画的是两个变量间的相互作用; 公式如下: 要理解互信息,首先得搞懂什么是条件熵。 --- 条件熵,指的是: 条件熵的基础是,条件概率。条件概率刻画的是,当时知道一件事儿时,另外一件事儿发生的概率有多大。 因此,条件熵,刻画了一个变量在给定另一个变量状态下的平均不确定性...
