PROBABILITY SEMINAR
TIME: 10:10 – 11:00 am
ROOM: Temple 303
SPEAKER: Professor Vasileios Maroulas
TITLE: "Improved particle filters and an application in the problem of multi-target tracking" -Part III
ABSTRACT: A novel approach for improving particle filters is presented. The suggested approach is based on Girsanov's change of measure theorem for stochastic differential equations.
Girsanov's theorem is used to design a Markov Chain Monte Carlo step which is appended to the particle filter and aims to bring the particle filter samples closer to the observations. The proposed approach is applied in the problem of multi-target tracking for both linear and nonlinear observation models. Also, a simple Metropolis Monte Carlo algorithm for tackling the target-observation association problem is presented. The numerical results show that the suggested approach can improve significantly the performance of a particle filter.
The talk will be based on joint works with Panos Stinis.
