Data Consistency Approach to Model Validation

1 code implementation17 Aug 2018 Andreas Svensson, Dave Zachariah, Petre Stoica, Thomas B. Schön

The contribution in this paper is a general criterion to evaluate the consistency of a set of statistical models with respect to observed data.

How consistent is my model with the data? Information-Theoretic Model Check

1 code implementation7 Dec 2017 Andreas Svensson, Dave Zachariah, Thomas B. Schön

The choice of model class is fundamental in statistical learning and system identification, no matter whether the class is derived from physical principles or is a generic black-box.

Probabilistic learning of nonlinear dynamical systems using sequential Monte Carlo

no code implementations7 Mar 2017 Thomas B. Schön, Andreas Svensson, Lawrence Murray, Fredrik Lindsten

We are concerned with the problem of learning probabilistic models of dynamical systems from measured data.

Learning of state-space models with highly informative observations: a tempered Sequential Monte Carlo solution

no code implementations6 Feb 2017 Andreas Svensson, Thomas B. Schön, Fredrik Lindsten

In particular, for learning of unknown parameters in nonlinear state-space models, methods based on the particle filter (a Monte Carlo method) have proven very useful.

A flexible state space model for learning nonlinear dynamical systems

no code implementations17 Mar 2016 Andreas Svensson, Thomas B. Schön

We consider a nonlinear state-space model with the state transition and observation functions expressed as basis function expansions.

Computationally Efficient Bayesian Learning of Gaussian Process State Space Models

no code implementations7 Jun 2015 Andreas Svensson, Arno Solin, Simo Särkkä, Thomas B. Schön

We present a procedure for efficient Bayesian learning in Gaussian process state space models, where the representation is formed by projecting the problem onto a set of approximate eigenfunctions derived from the prior covariance structure.

Sequential Monte Carlo Methods for System Identification

no code implementations20 Mar 2015 Thomas B. Schön, Fredrik Lindsten, Johan Dahlin, Johan Wågberg, Christian A. Naesseth, Andreas Svensson, Liang Dai

One of the key challenges in identifying nonlinear and possibly non-Gaussian state space models (SSMs) is the intractability of estimating the system state.

Marginalizing Gaussian Process Hyperparameters using Sequential Monte Carlo

no code implementations6 Feb 2015 Andreas Svensson, Johan Dahlin, Thomas B. Schön

Gaussian process regression is a popular method for non-parametric probabilistic modeling of functions.

Identification of jump Markov linear models using particle filters

no code implementations25 Sep 2014 Andreas Svensson, Thomas B. Schön, Fredrik Lindsten

Jump Markov linear models consists of a finite number of linear state space models and a discrete variable encoding the jumps (or switches) between the different linear models.
