Learning To Time Update

The time update is a critical component in navigation and tracking filters. Usually, physical dynamical models based on Newton’s laws are used to predict the motion of the vehicle. In this project, we aim to use data-driven methods and machine learning to learn the dynamics of the vehicle.

In many cases, the motion patterns of objects are very repeatable, but beforehand not known. This might be boats drifting along streams or cars following traffic rules. Today, the standard methods simply assume no more knowledge of the motion than that physical limitations with respect to accelerations etc are fulfilled.

Learning to time updateObviously, better knowledge of the underlying motion patterns would be of huge benefit. Learning these motion patterns is a problem that combines theory from classic estimation theory, as well as modern data driven machine learning methods.

The main challenge lies in exploiting the synergies possible by combining the two approaches in one common framework.

Learning to time update
The method automatically learns how cars drive in a three-way intersection using position measurements and a constant velocity model combined with a Gaussian Process model of maneuvers, resulting in improved localization and fast maneuver classification.
