Deterministic annealing algorithm: tutorial, application to pickup and delivery problem and computational aspects
… of DA method with Statistical Mechanics and Rate-Distortion Theory. Next, we present the application of DA method to pickup and deliver scheduling problem with time windows. Finally, a computational complexity analysis for DA is presented for a given temperature schedule. The case study …

Aggregated Learning: An Information Theoretic Framework to Learning with Neural Networks
… quantization problem. The classical results in rate-distortion theory then suggest that IB learning can benefit from a vector quantization approach, namely, simultaneously learning the representations of multiple input objects. Such an approach assisted with some variational techniques, result …

Control in the presence of an intelligent jammer with limited actions
… control in the presence of an intelligent and strategic jammer who is maliciously altering the control signal or observation signal in the communication network connecting the controller and the plant. The first formulation considers a dynamic zero-sum game between a controller and a jammer for …

Streaming of Markov Sources over Burst Erasure Channels
… following it. The minimum attainable compression rate for this setup R(B,W), termed the rate-recovery function, is investigated for discrete source with lossless recovery, and Gauss-Markov sources with a quadratic distortion measure. The above setup introduces a new problem in network information …

Subspace methods for portfolio design
… managed by portfolio managers. Modern Portfolio Theory (MPT) offers a mathematical method for portfolio optimization. It defines the risk as the standard deviation of the portfolio return and provides closed-form solution for the risk optimization problem where asset allocations are derived from. …

Structured vector quantizers in image coding
… methods are suggested. One is developed for moderate to high rate data compression while the other is effective for low to moderate data rate. In the first part of this thesis, a residual VQ using a low rate optimal VQ in the first-stage and a Gaussian codebook in the other stages are introduced. …

Information-theoretic bounds in learning algorithms
… to the next. To solve these problems in an accurate and data-efficient way, an active and adaptive learning framework is proposed, in which the labels of the most informative samples are actively queried from an unlabeled data pool, and the adaptation to the change is achieved by utilizing the …

Computing with unreliable resources : design, analysis and algorithms
… in the three parts of this thesis. We demonstrate that it is often necessary to introduce redundancy to achieve reliable computing, and this needs to be carried out judiciously to attain an appealing balance between reliability and resource usage. In particular, it is crucial to take the …

Information-theoretic metrics for security and privacy
… in the "small key" regime (i.e. when the key rate is smaller than the entropy rate of the message source). It is well known that security against computationally unbounded adversaries in such settings can only be achieved when the communicating parties share a key that is at least as long as …
