class filterpy.kalman.EnsembleKalmanFilter (x, P, dim_z, dt, N, hx, fx) [source] ¶. This implements the ensemble Kalman filter (EnKF). The EnKF uses an ensemble of hundreds to thousands of state vectors that are randomly sampled around the estimate, and adds perturbations at each update and predict step.
The Ensemble Kalman Filter and Smoother (EnKF & EnKS) are stochastic filtering methods based on Monte Carlo simulations. They are sequential and flexible ...

class EnsembleKalmanFilter (object): """ This implements the ensemble Kalman filter (EnKF). The EnKF uses an ensemble of hundreds to thousands of state vectors that are randomly sampled around the estimate, and adds perturbations at each update and predict step. It is useful for extremely large systems such as found in hydrophysics.
10.01.2021 · In Kalman filters, we iterate measurement (measurement update) and motion (prediction). And the update will use Bayes rule, which is nothing else but a product or a multiplication. In prediction,...

The KalmanFilter class comes equipped with two algorithms for prediction: the Kalman Filter and the Kalman Smoother. While the former can be updated recursively (making it ideal for online state estimation), the latter can only be done in batch.
What is EnKF (ensemble Kalman filter)? This implements the ensemble Kalman filter (EnKF). The EnKF uses an ensemble of hundreds to thousands of state vectors that are randomly sampled around the estimate, and adds perturbations at each update and predict step. It is useful for extremely large systems such as found in hydrophysics.

Implementing a Kalman Filter in Python is simple if it is broken up into its component steps. The component steps are modeled with individual functions. Note that these functions can be extended or modified to be used in other Kalman Filter applications.
