A stochastic network approach to clustering and visualising single-cell genomic count data
Thomas E. Bartlett, Swati Chandna, Sandipan Roy
Important tasks in the study of genomic data include the identification of groups of similar cells (for example by clustering), and visualisation of data summaries (for example by…
Change-Point Estimation in High-Dimensional Markov Random Field Models
Sandipan Roy, Yves Atchade, George Michailidis
This paper investigates a change-point estimation problem in the context of high-dimensional Markov Random Field models. Change-points represent a key feature in many dynamically e…
Bayesian Inference in Nonparametric Dynamic State-Space Models
Anurag Ghosh, Soumalya Mukhopadhyay, Sandipan Roy +1
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…
