Underwater Geomagnetic Localization Based on Adaptive Fission Particle-Matching Technology

open access: yesJournal of Marine Science and Engineering, 2023
The geomagnetic field constitutes a massive fingerprint database, and its unique structure provides potential position correction information. In recent years, particle filter technology has received more attention in the context of robot navigation ...

Multilevel Particle Filters [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2017
In this paper the filtering of partially observed diffusions, with discrete-time observations, is considered. It is assumed that only biased approximations of the diffusion can be obtained, for choice of an accuracy parameter indexed by $l$. A multilevel estimator is proposed, consisting of a telescopic sum of increment estimators associated to the ...

Feedback Particle Filter [PDF]

open access: yesIEEE Transactions on Automatic Control, 2013
A new formulation of the particle filter for nonlinear filtering is presented, based on concepts from optimal control, and from the mean-field game theory. The optimal control is chosen so that the posterior distribution of a particle matches as closely as possible the posterior distribution of the true state given the observations. This is achieved by

A Genetic Optimization Resampling Based Particle Filtering Algorithm for Indoor Target Tracking

open access: yesRemote Sensing, 2021
In indoor target tracking based on wireless sensor networks, the particle filtering algorithm has been widely used because of its outstanding performance in coping with highly non-linear problems.

Tempered Particle Filtering [PDF]

open access: yesFinance and Economics Discussion Series, 2016
The accuracy of particle filters for nonlinear state-space models crucially depends on the proposal distribution that mutates time t-1 particle values into time t values. In the widely-used bootstrap particle filter this distribution is generated by the state-transition equation.

A GENERIC PROBABILISTIC MODEL AND A HIERARCHICAL SOLUTION FOR SENSOR LOCALIZATION IN NOISY AND RESTRICTED CONDITIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
A generic probabilistic model, under fundamental Bayes’ rule and Markov assumption, is introduced to integrate the process of mobile platform localization with optical sensors.

Wrapped Particle Filtering for Angular Data

open access: yesIEEE Access, 2022
Particle filtering is probably the most widely accepted methodology for general nonlinear filtering applications. The performance of a particle filter critically depends on the choice of proposal distribution.

A weighted likelihood criteria for learning importance densities in particle filtering

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
Selecting an optimal importance density and ensuring optimal particle weights are central challenges in particle-based filtering. In this paper, we provide a two-step procedure to learn importance densities for particle-based filtering.

Semi-independent resampling for particle filtering [PDF]

open access: yes, 2017
Among Sequential Monte Carlo (SMC) methods,Sampling Importance Resampling (SIR) algorithms are based on Importance Sampling (IS) and on some resampling-based)rejuvenation algorithm which aims at fighting against weight degeneracy.

Nonlinear Compressive Particle Filtering [PDF]

open access: yes, 2013
Many systems for which compressive sensing is used today are dynamical. The common approach is to neglect the dynamics and see the problem as a sequence of independent problems. This approach has two disadvantages. Firstly, the temporal dependency in the
