Improved Calibration of Numerical Integration Error in Sigma-Point Filters

no code implementations28 Nov 2018 Jakub Prüher, Toni Karvonen, Chris. J. Oates, Ondřej Straka, Simo Särkkä

The sigma-point filters, such as the UKF, which exploit numerical quadrature to obtain an additional order of accuracy in the moment transformation step, are popular alternatives to the ubiquitous EKF.

Student-t Process Quadratures for Filtering of Non-Linear Systems with Heavy-Tailed Noise

no code implementations15 Mar 2017 Jakub Prüher, Filip Tronarp, Toni Karvonen, Simo Särkkä, Ondřej Straka

Advantage of the Student- t process quadrature over the traditional Gaussian process quadrature, is that the integral variance depends also on the function values, allowing for a more robust modelling of the integration error.
