Stage M2 / Ingénieur : Sequential Bayesian Inference Methods for Complex Dynamical Systems


Catégorie : Stagiaire


Subject

Many problems in different scientific domains can be described through statistical models that relate the sequential observed data to a hidden process through some unobserved parameters. In the Bayesian framework, the probabilistic estimation of the unknowns is represented by the posterior distribution of these parameters. However in most of the realistic models, the posterior is intractable and must be approximated. Importance Sampling (IS)-based algorithms are Monte Carlo methods that have shown a satisfactory performance in many problems of Bayesian inference.

In this project, we will apply and extend recent adaptive IS-based methods for probabilistic inference in complex non-linear high-dimensional systems. Novel adaptation schemes will be explored in order to overcome current limitations of such techniques. Many applications can be benefited from the development of these methodologies. In particular, we will apply the Bayesian inference techniques in problems such us tracking of space debris or prediction of the evolution of a biological system related to the formation and growth of cancer stem cells.
