Layered Synthesis of Latent Gaussian Trees
Ali Moharrer, Shuangqing Wei, George T. Amariucai +1
A new synthesis scheme is proposed to generate a random vector with prescribed joint density that induces a (latent) Gaussian tree structure. The quality of synthesis is shown by v…
Chernoff Information of Bottleneck Gaussian Trees
Binglin Li, Shuangqing Wei, Yue Wang +1
In this paper, our objective is to find out the determining factors of Chernoff information in distinguishing a set of Gaussian trees. In this set, each tree can be attained via an…
Synthesis of Gaussian Trees with Correlation Sign Ambiguity: An Information Theoretic Approach
Ali Moharrer, Shuangqing Wei, George T. Amariucai +1
In latent Gaussian trees the pairwise correlation signs between the variables are intrinsically unrecoverable. Such information is vital since it completely determines the directio…
