Implementation of Kalman Filter Estimation of Mean in Python using PyKalman, Bokeh and NSEPy

Kalman Filter is an optimal estimation algorithm to estimate the variable which can be measured indirectly and to find the best estimate of states by combining measurement from various sensors in the presence of noise.

Kalman filter is named after Rudolf E. Kálmán, one of the primary developers of its theory. Kalman filter has wide range of applications from aerospace Navigation, Robotics, Trajectory Optimization, Control Systems , Signal Processing, time series analysis and econometrics. Infact the very first application of kalman filter was made at NASA AMES center in the early 1960s during the feasibility study of circumlinear navigation control of the apollo space capsule.

Kalman Filters is ideal for systems which are continuously changing and well suited for building real time systems as kalman filter is a dynamic linear model, that is able to adapt to an ever changing environment. The major advantage of Kalman Filter is that it is predictive , adaptive as well and and it is really fast as it doesn’t tracks the historical data but rather the previous state.

When comes to implementation of Kalman filter python comes very handy as the librry PyKalman makes life easier rather than digging with complex math stuff
to calculate kalman estimation.
