Webby [22], we combine the Chow-Liu algorithm [27] with the techniques for growing networks developed in [28] to identify the underlying structure of an undirected consensus network. Constructing the Chow-Liu tree from statistical data does not require any matrix inversion; thereby, it is well-suited for large-scale problems. Furthermore, we have Webamong which tree graphical models are the most famous. The seminal work of Chow and Liu [4] contributed an efficient algorithm to compute the Maximum Likelihood Estimator (MLE) of tree structured graphical model based on empirical data, and constitutes one of the very few cases where the exact MLE can be solved efficiently. There are various ...
