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…

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…
