Learning Graphs from Linear Measurements: Fundamental Trade-offs and Applications
Tongxin Li, Lucien Werner, Steven H. Low
We consider a specific graph learning task: reconstructing a symmetric matrix that represents an underlying graph using linear measurements. We present a sparsity characterization…
Maximum Likelihood Upper Bounds on the Capacities of Discrete Information Stable Channels
Tongxin Li
Motivated by a greedy approach for generating {\it{information stable}} processes, we prove a universal maximum likelihood (ML) upper bound on the capacities of discrete informatio…
Quadratically Constrained Channels with Causal Adversaries
Tongxin Li, Bikash Kumar Dey, Sidharth Jaggi +2
We consider the problem of communication over a channel with a causal jamming adversary subject to quadratic constraints. A sender Alice wishes to communicate a message to a receiv…
Energy-efficient Decoders for Compressive Sensing: Fundamental Limits and Implementations
Tongxin Li, Mayank Bakshi, Pulkit Grover
The fundamental problem considered in this paper is "What is the \textit{energy} consumed for the implementation of a \emph{compressive sensing} decoding algorithm on a circuit?".…
Group Testing with Prior Statistics
Tongxin Li, Chun Lam Chan, Wenhao Huang +2
We consider a new group testing model wherein each item is a binary random variable defined by an a priori probability of being defective. We assume that each probability is small…
