State Estimation for Piecewise Affine State-Space Models
Rafael Rui, Tohid Ardeshiri, Henri Nurminen +2
We propose a filter for piecewise affine state-space (PWASS) models. In each filtering recursion, the true filtering posterior distribution is a mixture of truncated normal distrib…
Skew-t Filter and Smoother with Improved Covariance Matrix Approximation
Henri Nurminen, Tohid Ardeshiri, Robert Piché +1
Filtering and smoothing algorithms for linear discrete-time state-space models with skew-t-distributed measurement noise are proposed. The algorithms use a variational Bayes based…
Distributed Localization of Tree-structured Scattered Sensor Networks
Sina Khoshfetrat Pakazad, Emre Özkan, Carsten Fritsche +2
Many of the distributed localization algorithms are based on relaxed optimization formulations of the localization problem. These algorithms commonly rely on first-order optimizati…
Skew-t inference with improved covariance matrix approximation
Henri Nurminen, Tohid Ardeshiri, Robert Piche +1
Filtering and smoothing algorithms for linear discrete-time state-space models with skew-t distributed measurement noise are presented. The proposed algorithms improve upon our ear…
