Web5 Word examples: • Determination of planet orbit parameters from limited earth observations. • Tracking targets - eg aircraft, missiles using RADAR. • Robot Localisation and Map building from range sensors/ beacons. Why use the word “Filter”? The process of finding the “best estimate” from noisy data amounts to “filtering out” the noise. Webexample, it is common to use noise levels in the Kalman smoother well in excess of the actual noise to obtain practical robustness [3, §8]. In this paper we take a machine learning approach to the problem of tuning a Kalman smoother. We start with the observation that (by our denition) only the output is observed.

WebFor example a 10-bit ADC module will output a value in the range of 0..1023, note that 1023 = 2^10 -1. A 12-bit ADC module will output a value in the range of 0..4095, note that 4095 = 2^12-1.
