Hidden Markov Model with control input?

Given that HMMs and Kalman Filters are both state space models with recursive aspects and KFs allow for control inputs to influence the prediction at each step, I'm wondering if any similar methods ...

Tracking methods for pose estimation task

I'm working on the task of tracking the output of a pose estimation model. This model returns for each frame 17 joints for each person in the scene and I want to track each pose in order to assign a ...

How does Kalman filtering work backwards?

For time series missing value imputation I am using the Kalman filter/smoothing approach, given in the imputeTS package. As Kalman filter is iterative and needs a view data points to make its estimate ...

Is Kalman filtering a suitable approach to predict data from a set of/or a single feature?

I have multiple repeats of a time series that I would like to use to train a model to predict future repeats. The time series contains feature data (easy to measure) and target data (hard to measure). ...

Sensor fusion using recurrent neural network: obtaining a smoothed output

I am trying to use a recurrent neural network to perform sensor fusion for an inertial measurement unit. IMUs are commonly used in conjunction with a Kalman filter (KF), which performs both fusion of ...

Kalman filter for time series prediction

I have the information about the behaviour of 400 users across period of 1 months (30 days). Across those 30 days I measure 4 different information (let's call it A,B,C and D), hence I have a total of ...

Online noise removal techniques

There are lots of noise removal algorithms for offline dataset. I would like to ask if there are some suitable online implementations to remove noise of the data in real-time (similar to Kalman ...
