Latent Modularity in Multi-View Data

Andrea Cremaschi, Maria De Iorio, Garritt Page +1

In this article, we consider the problem of clustering multi-view data, that is, information associated to individuals that form heterogeneous data sources (the views). We adopt a…

Unbiased Parameter Estimation of Partially Observed Diffusions using Diffusion Bridges

Miguel Alvarez, Ajay Jasra

In this article we consider the estimation of static parameters for partially observed diffusion processes with discrete-time observations over a fixed time interval. In particular…

Bayesian Parameter Estimation for Partially Observed McKean-Vlasov Diffusions Using Multilevel Markov chain Monte Carlo

Ajay Jasra, Amin Wu

In this article we consider Bayesian estimation of static parameters for a class of partially observed McKean-Vlasov diffusion processes with discrete-time observations over a fixe…

Asymptotic Variance in the Central Limit Theorem for Multilevel Markovian Stochastic Approximation

Ajay Jasra, Abylay Zhumekenov

In this note we consider the finite-dimensional parameter estimation problem associated to inverse problems. In such scenarios, one seeks to maximize the marginal likelihood associ…

Bayesian Inference for Non-Synchronously Observed Diffusions

Ajay Jasra, Kengo Kamatani, Amin Wu

We consider the problem of Bayesian inference for bi-variate data observed in time but with observation times which occur non-synchronously. In particular, this occurs in a wide va…

Unbiased Parameter Estimation for Bayesian Inverse Problems

Neil K. Chada, Ajay Jasra, Mohamed Maama +1

In this paper we consider the estimation of unknown parameters in Bayesian inverse problems. In most cases of practical interest, there are several barriers to performing such esti…
