Including parameters in state space model from statsmodels

How can I compute the sigma points for UKF?

QUESTION

Including parameters in state space model from statsmodels

Asked 2022-Jan-03 at 16:00

Building up the model from a previous post, and the helpful answer, I've subclassed the MLEModel to encapsulate the model. I'd like to allow for two parameters q1 and q2 so that the state noise covariance matrix is generalized as in Sarkka (2013)'s example 4.3 (terms re-arranged for my convention):

I thought I would accomplish this with the update method below, but I'm running into problems with the fit method, as it returns a UFuncTypeError: Cannot cast ufunc 'multiply' output from dtype('complex128') to dtype('float64') with casting rule 'same_kind'. What am I missing here?

The error message you are receiving is about trying to set a complex value in a dtype=float matrix. You would get the same error from:

QUESTION

How can I compute the sigma points for UKF?

Asked 2020-Dec-16 at 16:19

Image above & tutorial: https://towardsdatascience.com/the-unscented-kalman-filter-anything-ekf-can-do-i-can-do-it-better-ce7c773cf88d

I am confused about how to compute the sigma points for the unscented Kalman filter. For me, mu is a 2-dim vector, so n is 5 and cov is a 2x2 matrix. lambda is 3-n, so 1. Now, I don't understand the index i, since non of the values/matrices are dependent on i. What would be the difference between X[1] and X[2]?

Thanks for any help, I think I'm probably just confused.. :)

I realized i simply stands for the i'th columnn.
