Meanings
plural Kalman filters
- An algorithm that uses a series of measurements observed over time, containing statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more precise than those based on a single measurement alone. They are used in navigation, signal processing, etc.
There is no doubt that complex notation can create a learning barrier and the notation involved in the Kalman filter can be quite formidable.
