Tree Structured Synthesis of Gaussian Trees
Ali Moharrer, Shuangqing Wei, George T. Amariucai +1
A new synthesis scheme is proposed to effectively generate a random vector with prescribed joint density that induces a (latent) Gaussian tree structure. The quality of synthesis i…
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…
Classifying Unrooted Gaussian Trees under Privacy Constraints
A. Moharrer, S. Wei, G. T. Amariucai +1
In this work, our objective is to find out how topological and algebraic properties of unrooted Gaussian tree models determine their security robustness, which is measured by our p…
