Web12 de abr. de 2024 · The Kalman filter is a frequently used technique to infer, assuming a model of the system, the parameters of the model from uncertain observations. A well-known implementation of the Kalman filter, the unscented Kalman filter (UKF), was recently shown to be able to infer the connectivity of a set of coupled chaotic oscillators. Web18 de jun. de 2024 · There are multiple versions of the Kalman filter. The idea behind the filter is this: You keep track of a vector of states of the system (i.e. position, speed, acceleration and noise) and update it for each new data. When post-processing data you can initialize de filter on a forward pass and then use the backwards for estimation.
