Largest eigenvalue of positive mean Gaussian matrices
Arijit Chakrabarty, Rajat Subhra Hazra, Moumanti Podder
This short note studies the fluctuations of the largest eigenvalue of symmetric random matrices with correlated Gaussian entries having positive mean. Under the assumption that the…
Nonparametric method of structural break detection in stochastic time series regression model
Archi Roy, Moumanti Podder, Soudeep Deb
We propose a novel nonparametric test to detect structural breaks in the conditional mean and/or variance of a time series. Our method does not assume any specific parametric form…
Percolation games on rooted, edge-weighted random trees
Sayar Karmakar, Moumanti Podder, Souvik Roy +1
Consider a rooted Galton-Watson tree , to each of whose edges we assign, independently, a weight that equals with probability , with probability and …
Learning models on rooted regular trees with majority update policy: convergence and phase transition
Moumanti Podder, Anish Sarkar
We study a learning model in which an agent is stationed at each vertex of , the rooted tree in which each vertex has children. At any time-step $t \in \mathbb{…
Generalized percolation games on the -dimensional square lattice, and ergodicity of associated probabilistic cellular automata
Dhruv Bhasin, Sayar Karmakar, Moumanti Podder +1
Each vertex of the infinite -dimensional square lattice graph is assigned, independently, a label that reads trap with probability , target with probability , and open wit…
