Abstract
A new exact recursive filter is derived for nonlinear estimation problems. The new nonlinear theory includes the Kalman filter as a special case. This filter is practical to implement in real- time applications, and it has a computational complexity that is comparable to the Kalman filter. The measurements are made in discrete time, but the random process to be estimated evolves in continuous time.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

Skewed approach to filtering

Simon Julier
- 03 Sep 1998 - 
TL;DR: A tractable, convenient algorithm which can be used to predict the first three moments of a distribution is developed by extending the sigma point selection scheme of the unscented transformation to capture the mean, covariance and skew.

Approximation Analysis of Stochastic Gradient Langevin Dynamics by using Fokker-Planck Equation and Ito Process

TL;DR: This work theoretically analyze the SGLD algorithm with constant stepsize and shows by using the Fokker-Planck equation that the probability distribution of random variables generated by the S GLD algorithm converges to the Bayesian posterior.

Soft Uplink Load Estimation in WCDMA

TL;DR: This paper first proves that the uplink load, which is expressed as the rise over thermal (RoT), is unobservable with any linear estimation technique using measurements in a single radio base station (RBS) of received total wideband power (RTWP) and cell channel powers.

Control for Localization of Targets Using Range-Only Sensors.

TL;DR: An application of a novel framework and algorithms for conservatively and recursively incorporating information obtained through sensors that yield observations that are non-linear functions of the state and finding control inputs that continuously improve the quality of the resulting estimates is presented.

Exact finite-dimensional filters for certain diffusions with nonlinear drift

TL;DR: In this paper, the authors considered the problem of estimating a diffusion in independent Wiener processes by solving the stochastic DE dx t =f(x t )dt+dw t on the basis of noisy observations defined bydy t =x t dt+db t.

New exact nonlinear filters with large Lie algebras

TL;DR: In this article, a nonlinear filter is obtained from the original filter by smoothing the output through an n-pole linear system before adding observation noise in the usual way, which adds 2n to the Lie algebra dimension.
