Recent Research Results/News

Below you will find a brief list of news related to the research where I am involved.


  • Sep 23, 2013: My new web-site at Uppsala University is finally on-line and you will find it here.

  • Sep 5, 2013: We have been able to construct and learn a Gaussian process (GP) state space model while keeping alive the entire nonparametric richness of this kind of model. We believe that it is the first time that this has been achieved. The key allowing us to do this is a new PMCMC method known as Particle Gibbs with Ancestor Sampling (PG-AS). We have a feeling that these inference methods are useful also for other Bayesian nonparametric models. The new results will be published at NIPS in December.

  • Aug 14, 2013: In September 2013, I will move to Uppsala University as Professor of the Chair of Automatic Control. I will continue to be affiliated with Linköping University.

The grading committee consists of Prof. Tobias Rydén (Lynx Asset Management), Doc. Joakim Jaldén (KTH) and Prof. Mattias Villani (Linköping University). The thesis is entitled "Particle filters and Markov chains for learning of dynamical systems".
  • June 17, 2013: Our new tutorial on particle smoothing methods is now accepted for publication in Foundations and Trends in Machine Learning,
    • [1] Fredrik Lindsten and Thomas B. Schön. Backward simulation methods for Monte Carlo statistical inference. Foundations and Trends in Machine Learning, 2013. [pdf]
    This paper is written with the intent to be a self-contained introduction to particle smoothing in a general setting, not just confined to standard nonlinear state space models. More precisely, we discuss using forward filtering/backward simulation techniques for addressing both smoothing and parameter inference problems.
  • May 28, 2013: Johan Kihlberg and Simon Tegelid have been awarded the best Master's thesis award 2012 by Dataföreningen - öst. The thesis is entitled "Map Aided Indoor Positioning" and it is available for download by clicking here.
  • May 22, 2013: I have been awarded the Best PhD thesis award 2013 by The European Association for Signal Processing (EURASIP). "The selection process is based on the evaluation of the impact of the theses, their subsequent journal and conference publications and related citations received, and on the review reports of three independent reviewers as well as on the download statistics." The thesis entitled "Estimation of Nonlinear Dynamic Systems: Theory and Applications" is available here and the announcement is available here.
  • Apr 22, 2013: I am very glad to welcome Roger Frigola, who is visiting our team for a couple of months. Roger is a PhD student with the Machine learning group at the University of Cambridge (UK).
  • Mar 7, 2013: Our new method for Wiener system identification has been accepted for publication in Automatica. The method avoids making strong assumptions, such as monotonicity, on the nonlinear mapping. Stochastic disturbances, entering both as measurement noise and as process noise, are also straightforwardly handled. The inference algorithm is based on an efficient particle Markov chain Monte Carlo (PMCMC) method, referred to as particle Gibbs with ancestor sampling (PG-AS).

  • Sep 4, 2012: We have developed a new particle MCMC method, that we refer to as particle Gibbs with ancestor sampling (PG-AS). Similarly to the existing PG with backward simulation (PG-BS) procedure, we use backward sampling to (considerably) improve the mixing of the PG kernel. Instead of using separate forward and backward sweeps as in PG-BS, we achieve the same effect in a single forward sweep. This result has been accepted for publication at NIPS this year,
