Hello,
I want to implement the Kalman Filter in Pytorch. For that I have written a custom KalmanCell(nn.Module)
that performs a Kalman update/predict step for one time step.
I want to integrate the Cell in a module that takes as inputs a time series and outputs the filtered/noise-free time series.
My question is, how do I implement the module that calls KalmanCell without iterating over all time steps of the input time series?
For now I have a loop over the length of the time series (T).
for t in range(self.T):
x_post, P_post, x_prior, P_prior = self._KalmanCell(x_prior, P_prior, input[:,t])
Is there a way to get rid of the loop? Can I inherit from RNN class? If so how would I write this?
For now I only saw examples with loop over time such as this time series example from Pytorch.
I would appreciate any suggestions. Thanks!
