Belief Propagation and Algorithms for Mean-Field Combinatorial Optimisations
(2017-11-15)We study combinatorial optimization problems on graphs in the mean-field model, which assigns independent and identically distributed random weights to the edges of the graph. Specifically, we focus on two generalizations ... -
Computational Models of Perceptual Space : From Simple Features to Complex Shapes
(2018-02-15)Dissimilarity plays a very important role in object recognition. But, finding perceptual dissimilarity between objects is non-trivial as it is not equivalent to the pixel dissimilarity between the objects (For example, two ... -
Cooperative Communication and QoS in Infrastructure WLANs
(2018-05-08)IEEE 802.11 wireless LANs operating in the infrastructure mode are extremely popular and have seen widespread deployment because of their convenience and cost efficiency. A large number of research studies have investigated ... -
Delay Minimization of an M/M/1 Point-to-Point Link Model Subject to Throughput and Power Constraints
(2018-02-15)In this thesis, we address the problem of minimizing the average delay of data pack-ets served by a transmitter on a static, point-to-point link. The transmitter dynamically chooses state-dependent admission and transmission ... -
