Influential Node Detection in Implicit Social Networks using Multi-task Gaussian Copula Models
Qunwei Li, Bhavya Kailkhura, Jayaraman J. Thiagarajan +2
Influential node detection is a central research topic in social network analysis. Many existing methods rely on the assumption that the network structure is completely known \text…
Detection of Single vs Multiple Antenna Transmission Systems Using Pilot Data
Thakshila Wimalajeewa, Pramod K Varshney, Wei Su
In this paper, we consider the problem of classifying the transmission system when it is not known a priori whether the transmission is via a single antenna or multiple antennas. T…
Towards the Design of Prospect-Theory based Human Decision Rules for Hypothesis Testing
V. Sriram Siddhardh Nadendla, Swastik Brahma, Pramod K. Varshney
Detection rules have traditionally been designed for rational agents that minimize the Bayes risk (average decision cost). With the advent of crowd-sensing systems, there is a need…
Detection with Multimodal Dependent Data Using Low Dimensional Random Projections
Thakshila Wimalajeewa, Pramod K. Varshney
Performing likelihood ratio based detection with high dimensional multimodal data is a challenging problem since the computation of the joint probability density functions (pdfs) i…
On Strategic Multi-Antenna Jamming in Centralized Detection Networks
V. Sriram Siddhardh Nadendla, Vinod Sharma, Pramod K. Varshney
In this paper, we model a complete-information zero-sum game between a centralized detection network with a multiple access channel (MAC) between the sensors and the fusion center…
Optimized Sensor Collaboration for Estimation of Temporally Correlated Parameters
Sijia Liu, Swarnendu Kar, Makan Fardad +1
In this paper, we aim to design the optimal sensor collaboration strategy for the estimation of time-varying parameters, where collaboration refers to the act of sharing measuremen…
