“…These approaches can be primarily classified into two categories, approximating either the nonlinear function or the nonlineartransformed PDFs. The former, with typical examples of extended KF (EKF), modal KF (Mohammaddadi et al, 2017), divided difference filter (Nørgaard et al, 2000;Wang et al, 2017), and Fourier-Hermite KF (Sarmavuori and Särkkä, 2012), seeks functions' approximation using polynomial expansions (e.g., Taylor series, Fourier-Hermite series, Stirling's interpolation, or Modal series). The latter, with representative examples of unscented KF (UKF) (Julier and Uhlmann, 2004), Gauss-Hermite filter and central difference filter (Ito and Xiong, 2000), cubature KF (CKF) (Arasaratnam and Haykin, 2009;Jia et al, 2013), sparse-grid quadrature filter (Arasaratnam and Haykin, 2008;Jia et al, 2012), stochastic integration filter (Duník et al, 2013), and iterated posterior linearization filter (IPLF) (García-Fernández et al, 2015b;Raitoharju et al, 2017), is based on a set of deterministically chosen weighted sigma points.…”
