Convergence rates of Gaussian ODE filters [PDF]

open access: yesStatistics and Computing, 2020
AbstractA recently introduced class of probabilistic (uncertainty-aware) solvers for ordinary differential equations (ODEs) applies Gaussian (Kalman) filtering to initial value problems. These methods model the true solutionxand its firstqderivativesa priorias a Gauss–Markov process$${\varvec{X}}$$X, which is then iteratively conditioned on information

Design and Analysis of 5G Optical Communication System for Various Filtering Operations using Wireless Optical Transmission

open access: yesResults in Physics, 2019
In this paper, the Optical Wireless Communication (OWC) channels for different optical filters are analysed and compared with their previous model. Performance analysis is done using different optical filters namely Bessel, Trapezoidal, Gaussian and ...

A numerical integration-based Kalman filter for moderately nonlinear systems

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2020
This paper introduces a computationally efficient data assimilation scheme based on Gaussian quadrature filtering that potentially outperforms current methods in data assimilation for moderately nonlinear systems.

A nonlinear edge –preserving smoothing filter for edge detection on color and gray satellite images

open access: yesIraqi Journal of Physics, 2019
A nonlinear filter for smoothing color and gray images corrupted by Gaussian noise is presented in this paper. The proposed filter designed to reduce the noise in the R,G, and B bands of the color images and preserving the edges.

Multiplicative Gaussian Particle Filter

open access: yesCoRR, 2020
We propose a new sampling-based approach for approximate inference in filtering problems. Instead of approximating conditional distributions with a finite set of states, as done in particle filters, our approach approximates the distribution with a weighted sum of functions from a set of continuous functions.

An Improved Gaussian Sum Extended Kalman Filter With Colored Noise for GNSS/SINS Tightly Coupled Positioning and Attitude Determination Systems

open access: yesIEEE Access
The Gaussian sum extended Kalman filter (GSEKF), as a nonlinear non-Gaussian filter, disregards the impact of colored noise components in non-Gaussian noise engendered by external interference, which may compromise the estimation accuracy in global ...

Machine Learning Algorithm for Surface Quality Analysis of Friction Stir Welded Joint

open access: yesJournal of Mechanical Engineering, 2020
The Friction Stir Welding process usually produces weld members of good quality compared to composite weld made with a standard welding process. However, there is a possibility of the formation of various defects if the input parameters are not properly ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
