Information theoretic sensor management
… studies sensor management problems in which information theoretic quantities such as entropy are utilized to measure detection or estimation performance. The work has two emphases: Firstly, we seek performance bounds which guarantee performance of the greedy heuristic and derivatives thereof …

Information theoretic design of breast sonography
… procedure to maximize diagnostic image information content available to readers. Our previous study revealed that the Wiener filter, derived as a stationary approximation of the ideal observer and operating on RF echo data, generally improved discriminability except for one case …

Information theoretic limits of metagenomic binning
… principle for Markov processes, we establish the information-theoretic limit for perfect binning. Specifically, we show that the length of the contigs must scale with the inverse of the Chernoff Information between the two most similar species. Our result also implies that contigs should be binned …

Information-theoretic bounds in learning algorithms
… machine learning algorithms from an information-theoretic point of view. More specifically, we apply information-theoretic tools to construct performance bounds for the learning algorithms, with the goal of deepening the understanding of current algorithms and inspiring new learning …

Information theoretic bounds for distributed computation
… the performance criterion is guaranteed. Using Information Theoretic inequalities, I derive an algorithm-independent lower bound on the computation time. The bound is a function of the uncertainty in the function to be estimated, via its differential entropy, and the desired accuracy level, as …

Information theoretic analysis of watermarking systems
… to the public in order to embed some extra information. The embedding should be transparent (i.e., the modified data should be similar to the original data) and robust (i.e., the information should be recoverable even if the data is modified further). In this thesis, we describe the …

Information theoretic advances in zero-knowledge
… proofs have an intimate relation to notions from information theory. In particular, the class of all problems possessing statistical zero-knowledge proofs (SZK) was shown to have complete problems characterized by the statistical distance (Sahai and Vadhan [JACM, 20031) and entropy difference …

Information-theoretic aspects of quantum channels
Quantum information theory is an important element of quantum computing and quantum communication systems. Whenever a quantum computer needs to send an output state to another party, or two parties need to establish quantum entanglement or secure keys via quantum communication, a quantum channel is …

Information Theoretic Limits of State-dependent Networks
<p>We investigate the information theoretic limits of two types of state-dependent models in this dissertation. These models capture a wide range of wireless communication scenarios where there are interference cognition among transmitters. Hence, information theoretic studies of these models …

Information-theoretic limitations of distributed information processing
In a generic distributed information processing system, a number of agents connected by communication channels aim to accomplish a task collectively through local communications. The fundamental limits of distributed information processing problems depend not only on the intrinsic difficulty of the …

An information theoretic approach to veridical hallucination
… derive from a branch of signal theory, called Information Theory. Information Theory is a formal calculus for quantifying and computing the information content of a source or a signal carrying information about a source. It is an attempt to formalize an intuitive notion of information that we …

Information-theoretic metrics for security and privacy
… cryptography, privacy and estimation through the information-theoretic lens. We introduce information-theoretic metrics and associated results that shed light on the fundamental limits of what can be learned from noisy data. These metrics and results, in turn, are used to evaluate and design both …

Information Theoretic Methods For Biometrics, Clustering, And Stemmatology
… one which focuses on clustering. We establish an information theoretic framework and the fundamental trade-off between utility of biometric systems and security of biometric systems. The utility includes person identification and secret binding, while template protection, privacy, and secrecy …
