Hello, everyone. I am attempting to use the Covariance_filter as an EKF for a non-linear model. However, I do not understand which type of model class to use, and how to specify the data for the models, even after looking at the Bayesian Filtering overview. I'm pretty sure I need to use a linrz_predict_model (or something like that) but beyond that... The main problem is that the elements of the f function I want to use for the model are exponential. It's non-linear, with noise, but no control (it's essentially 'the object I'm trying to predict is walking around randomly, but within the laws of physics') How do you specify that? I've been looking at the Welch and Bishop introduction and trying to compare back to Bayes++, but with no avail. I'm fairly sure I could use the libraries if my model was linear, but I don't quite see how to put the non-linearity in there. The documentation doesn't make it completely clear what all the pieces that I'm specifying are. Is there any help anyone could offer? Thanks, Mike Simon |
