Forward Smoothing and Online EM in changepoint systems

Presented by: 
S Yildirim [Stats Lab]
Date: 
Monday 26th September 2011 - 12:40 to 12:50
Venue: 
INI Seminar Room 1
Abstract: 
In this talk, I will focus on forward smoothing in changepoint systems, which are gen- erally used to model the heterogeneity in the statistical data. After showing the SMC implementation of forward smoothing, I will show how we can perform the online EM algorithm for parameter estimation in changepoint systems.
