In Chapter 3 in the last sentence of the first paragraph of the section Total Probability Theorem i think it should say posterior instead of prior. The probability of being at any position 𝑖 at time 𝑡 can be written as 𝑃(𝑋𝑡𝑖) . We computed that as the sum of the prior at time 𝑡−1 𝑃(𝑋𝑡−1𝑗)...

https://nbviewer.org/github/rlabbe/Kalman-and-Bayesian-Filters-in-Python/blob/master/02-Discrete-Bayes.ipynb In the Discrete Bayes chapter, we have the formula for the discrete convolution: For t=0 this always yields just one value that is being added. This seems incorrect to me. Shouldn't the corr...

Can an Unscented Kalman Filter encode seasonality in the data? If so, what is the recommended way of doing it? Are there any references out there for introducing seasonality on Kalman Filter?

In 02-Discrete-Bayes.ipynb in the chapter The Discrete Bayes Algorithm you define the following function with the signature discrete_bayes_sim(prior, kernel, measurements, z_prob, hallway). The parameter prior is unused.

First thank you for your amazing book. I went through most of it and it had been of invaluable help. I was wondering if you had some advice when dealing with non normal process or sensor noise. You always model noise as discrete white noise. How would you adapt the UKF with a noise that is following...

Hi, this is an amazing content. I would like to filter my 2D signal to obtain both the velocity and acceleration at a time t, in order to estimate a CTRA model. Which method would you recommend to me? I am using the Argoverse Motion Forecasting dataset. An example of what I am trying to do is as fol...

First of all, thank you very much for this learning material, I really wish there were similar tutorials for other engineering areas! I think the central limit theorem is slightly off in chapter 3: What does this curve mean? Assume we have a thermometer which reads 22°C. No thermometer is perfectly...

In Kalman_filter.update(), dot(PHT,self.SI) does not work because PHT is 21 whilst self.SI is 11. so dot can not compute these two matrixs with different dimensions. Therefore, we should change it to PHT*self.SI. This is also true of other functions such as dot(self.K,self.y)
