State space partitioning based on constrained spectral clustering for block particle filtering

no code implementations7 Mar 2022 Rui Min, Christelle Garnier, François Septier, John Klein

The particle filter (PF) is a powerful inference tool widely used to estimate the filtering distribution in non-linear and/or non-Gaussian problems.
