Bayesian Inference in Nonparametric Dynamic State-Space Models
Anurag Ghosh, Soumalya Mukhopadhyay, Sandipan Roy, Sourabh Bhattacharya
Nov 01, 2014
We introduce state-space models where the functionals of the observational and the evolutionary equations are unknown, and treated as random functions evolving with time. Thus, our model is nonparametric and generalizes the...

Consistent Multiple Change-point Estimation with Fused Gaussian Graphical Models
Alex J. Gibberd, Sandipan Roy
Apr 01, 2021

We consider the consistency properties of a regularised estimator for the simultaneous identification of both changepoints and graphical dependency structure in multivariate time-series. Traditionally, estimation of Gaussian...

Change-Point Estimation in High-Dimensional Markov Random Field Models
Sandipan Roy, Yves Atchade, George Michailidis

Likelihood Inference for Large Scale Stochastic Blockmodels with Covariates based on a Divide-and-Conquer Parallelizable Algorithm with Communication
Sandipan Roy, Yves Atchadé, George Michailidis
Jul 10, 2019

We consider a stochastic blockmodel equipped with node covariate information, that is helpful in analyzing social network data. The key objective is to obtain maximum likelihood estimates of the model parameters. For this...

Risk of antimicrobial-associated organ injury among the older adults
Tichawona Chinzowu, Sandipan Roy, Prasad S Nishtala
Dec 01, 2021

BACKGROUND: Older adults (aged 65 years and above) constitute the fastest growing population cohort in the western world. There is increasing evidence that the burden of infections disproportionately affects older adults, and...
