A Practical Approach to Navigating the Tradeoff Between Privacy and Precise Utility
Chandra Sharma, George Amariucai
Due to the recent popularity of online social networks, coupled with people's propensity to disclose personal information in an effort to achieve certain gratifications, the proble…
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…
Half-Duplex Active Eavesdropping in Fast Fading Channels: A Block-Markov Wyner Secrecy Encoding Scheme
George T. Amariucai, Shuangqing Wei
In this paper we study the problem of half-duplex active eavesdropping in fast fading channels. The active eavesdropper is a more powerful adversary than the classical eavesdropper…
