Sequential Detection with Mutual Information Stopping Cost
Vikram Krishnamurthy, Robert Bitmead, Michel Gevers +1
This paper formulates and solves a sequential detection problem that involves the mutual information (stochastic observability) of a Gaussian process observed in noise with missing…
Real-Time Reinforcement Learning of Constrained Markov Decision Processes with Weak Derivatives
Vikram Krishnamurthy, Felisa Vazquez Abad
We present on-line policy gradient algorithms for computing the locally optimal policy of a constrained, average cost, finite state Markov Decision Process. The stochastic approxim…
Biosensor Arrays for Estimating Molecular Concentration in Fluid Flows
Maryam Abolfath-Beygi, Vikram Krishnamurthy
This paper constructs dynamical models and estimation algorithms for the concentration of target molecules in a fluid flow using an array of novel biosensors. Each biosensor is con…
Average-Consensus Algorithms in a Deterministic Framework
Kevin Topley, Vikram Krishnamurthy
We consider the average-consensus problem in a multi-node network of finite size. Communication between nodes is modeled by a sequence of directed signals with arbitrary communicat…
QoS Provisioning for Multimedia Transmission in Cognitive Radio Networks
F. Richard Yu, Bo Sun, Vikram Krishnamurthy +1
In cognitive radio (CR) networks, the perceived reduction of application layer quality of service (QoS), such as multimedia distortion, by secondary users may impede the success of…
Intent Inference and Syntactic Tracking with GMTI Measurements
Alex Wang, Vikram Krishnamurthy, Bhashyam Balaji
In conventional target tracking systems, human operators use the estimated target tracks to make higher level inference of the target behaviour/intent. This paper develops syntacti…
