Anomaly Detection Under Controlled Sensing Using Actor-Critic Reinforcement Learning
Geethu Joseph, M. Cenk Gursoy, Pramod K. Varshney
We consider the problem of detecting anomalies among a given set of processes using their noisy binary sensor measurements. The noiseless sensor measurement corresponding to a norm…
Output Controllability of a Linear Dynamical System with Sparse Controls
Geethu Joseph
In this paper, we study the conditions to be satisfied by a discrete-time linear system to ensure output controllability using sparse control inputs. A set of necessary and suffici…
Measurement Bounds for Compressed Sensing in Sensor Networks with Missing Data
Geethu Joseph, Pramod K. Varshney
In this paper, we study the problem of sparse vector recovery at the fusion center of a sensor network from linear sensor measurements when there is missing data. In the presence o…
Controllability of Network Opinion in Erdos-Renyi Graphs using Sparse Control Inputs
Geethu Joseph, Buddhika Nettasinghe, Vikram Krishnamurthy +1
This paper considers a social network modeled as an Erdos Renyi random graph. Each individual in the network updates her opinion using the weighted average of the opinions of her n…
Controllability of a Linear System with Nonnegative Sparse Controls
Geethu Joseph
This paper studies controllability of a discrete-time linear dynamical system using nonnegative and sparse inputs. These constraints on the control input arise naturally in many re…
