Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general introduction to Sequential Monte Carlo (SMC) methods, also known as particle filters. These methods have become a staple for the sequential analysis of data in such diverse fields as signal processing, epidemiology, machine learning, population ecology, quantitative finance, and robotics. The coverage is comprehensive, ranging from the underlying theory to computational implementation, methodology, and diverse applications in various areas of science. This is achieved by describing SMC algorithms as particular cases of a general framework, which involves concepts such as Feynman-Kac distributions, and tools such as importance sampling and resampling. This general framework is used consistently throughout the book. Extensive coverage is provided on sequential learning (filtering, smoothing) of state-space (hidden Markov) models, as this remains an important application of SMC methods. More recent applications, such as parameter estimation of these models (through e.g. particle Markov chain Monte Carlo techniques) and the simulation of challenging probability distributions (in e.g. Bayesian inference or rare-event problems), are also discussed. The book may be used either as a graduate text on Sequential Monte Carlo methods and state-space modeling, or as a general reference work on the area. Each chapter includes a set of exercises for self-study, a comprehensive bibliography, and a “Python corner,” which discusses the practical implementation of the methods covered. In addition, the book comes with an open source Python library, which implements all the algorithms described in the book, and contains all the programs that were used to perform the numerical experiments.

This book was released on 2022-06-01 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: In these notes, we introduce particle filtering as a recursive importance sampling method that approximates the minimum-mean-square-error (MMSE) estimate of a sequence of hidden state vectors in scenarios where the joint probability distribution of the states and the observations is non-Gaussian and, therefore, closed-form analytical expressions for the MMSE estimate are generally unavailable. We begin the notes with a review of Bayesian approaches to static (i.e., time-invariant) parameter estimation. In the sequel, we describe the solution to the problem of sequential state estimation in linear, Gaussian dynamic models, which corresponds to the well-known Kalman (or Kalman-Bucy) filter. Finally, we move to the general nonlinear, non-Gaussian stochastic filtering problem and present particle filtering as a sequential Monte Carlo approach to solve that problem in a statistically optimal way. We review several techniques to improve the performance of particle filters, including importance function optimization, particle resampling, Markov Chain Monte Carlo move steps, auxiliary particle filtering, and regularized particle filtering. We also discuss Rao-Blackwellized particle filtering as a technique that is particularly well-suited for many relevant applications such as fault detection and inertial navigation. Finally, we conclude the notes with a discussion on the emerging topic of distributed particle filtering using multiple processors located at remote nodes in a sensor network. Throughout the notes, we often assume a more general framework than in most introductory textbooks by allowing either the observation model or the hidden state dynamic model to include unknown parameters. In a fully Bayesian fashion, we treat those unknown parameters also as random variables. Using suitable dynamic conjugate priors, that approach can be applied then to perform joint state and parameter estimation.

Available in PDF, EPUB and Kindle. Book excerpt: A central problem in numerous applications is estimating the unknown parameters of a system of ordinary differential equations (ODEs) from noisy measurements of a function of some of the states at discrete times. Formulating this dynamic inverse problem in a Bayesian statistical framework, state and parameter estimation can be performed using sequential Monte Carlo (SMC) methods, such as particle filters (PFs) and ensemble Kalman filters (EnKFs).Addressing the issue of particle retention in PF-SMC, we propose to solve ODE systems within a PF framework with higher order numerical integrators which can handle stiffness and to base the choice of the innovation variance on estimates of discretization errors. Using linear multistep method (LMM) numerical solvers in this context gives a handle on the stability and accuracy of propagation, and provides a natural and systematic way to rigorously estimate the innovation variance via well-known local error estimates.We explore computationally efficient implementations of LMM PF-SMC by considering parallelized and vectorized formulations. While PF algorithms are known to be amenable to parallelization due to the independent propagation of each particle, by formulating the problem in a vectorized fashion, it is possible to arrive at an implementation of the method which takes full advantage of multiple processors.We employ a variation of LMM PF-SMC in estimating unknown parameters of a tracer kinetics model from sequences of real positron emission tomography scan data. A combination of optimization and statistical inference is utilized: nonlinear least squares finds optimal starting values, which then act as hyperparameters in the Bayesian framework. The LMM PF-SMC algorithm is modified to allow variable time steps to accommodate the increase in time interval length between data measurements from beginning to end of the procedure, keeping the time step the same for each particle.We also apply the idea of linking innovation variance with numerical integration error estimates to EnKFs by employing a stochastic interpretation of the discretization error in numerical integrators, extending the technique to deterministic, large-scale nonlinear evolution models. The resulting algorithm, which introduces LMM time integrators into the EnKF framework, proves especially effective in predicting unmeasured system components.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive treatment of inference for hidden Markov models, including both algorithms and statistical theory. Topics range from filtering and smoothing of the hidden Markov chain to parameter estimation, Bayesian methods and estimation of the number of states. In a unified way the book covers both models with finite state spaces and models with continuous state spaces (also called state-space models) requiring approximate simulation-based algorithms that are also described in detail. Many examples illustrate the algorithms and theory. This book builds on recent developments to present a self-contained view.
