Center node: "statistical physics and information theory perspectives on linear inverse problems"
  Abstract: Many real-world problems in machine learning, signal processing, and communications assume that an unknown vector $x$ is measured by a matrix A, resulting in a vector $y=Ax+z$, where $z$ denotes the noise; we call this a single measurement vector (SMV) problem. Sometimes, multiple dependent vectors $x^{(j)}, j\in \{1,...,J\}$, are measured at the same time, forming the so-called multi-measurement vector (MMV) problem. Both SMV and MMV are linear models (LM's), and the process of estimating the underlying vector(s) $x$ from an LM given the matrices, noisy measurements, and knowledge of the noise statistics, is called a linear inverse problem. In some scenarios, the matrix A is stored in a single processor and this processor also records its measurements $y$; this is called centralized LM. In other scenarios, multiple sites are measuring the same underlying unknown vector $x$, where each site only possesses part of the matrix A; we call this multi-processor LM. Recently, due to an ever-increasing amount of data and ever-growing dimensions in LM's, it has become more important to study large-scale linear inverse problems. In this dissertation, we take advantage of tools in statistical physics and information theory to advance the understanding of large-scale linear inverse problems. The intuition of the application of statistical physics to our problem is that statistical physics deals with large-scale problems, and we can make an analogy between an LM and a thermodynamic system. In terms of information theory, although it was originally developed to characterize the theoretic limits of digital communication systems, information theory was later found to be rather useful in analyzing and understanding other inference problems.
