Efficient, Effective and Well Justified Estimation of Active Nodes within a Cluster
Md Mahmudul Hasan, Shuangqing Wei, Ramachandran Vaidyanathan
Reliable and efficient estimation of the size of a dynamically changing cluster in an IoT network is critical in its nominal operation. Most previous estimation schemes worked with…
Latent Factor Analysis of Gaussian Distributions under Graphical Constraints
Md Mahmudul Hasan, Shuangqing Wei, Ali Moharrer
We explore the algebraic structure of the solution space of convex optimization problem Constrained Minimum Trace Factor Analysis (CMTFA), when the population covariance matrix $Σ_…
Algebraic Properties of Wyner Common Information Solution under Graphical Constraints
Md Mahmudul Hasan, Shuangqing Wei, Ali Moharrer
The Constrained Minimum Determinant Factor Analysis (CMDFA) setting was motivated by Wyner's common information problem where we seek a latent representation of a given Gaussian ve…
