Machine Learning Coffee seminar: "The Power of Gaussian Processes: Magnetic Localisation and Mapping" Arno Solin

Weekly seminars held jointly by Aalto University and the University of Helsinki.

Helsinki region machine learning researchers will start our week by an exciting machine learning talk. The aim is to gather people from different fields of science with interest in machine learning. Porridge and coffee is served at 9:00 and the talk will begin at 9:15.

The Power of Gaussian Processes: Magnetic Localisation and Mapping

Arno Solin
Professor, Aalto University

Abstract: Gaussian processes (GPs) are convenient tools for model-building and inference. This talk goes through how to encode knowledge from high-school physics into a GP model for the ambient magnetic field (observed by a smartphone compass). Small disturbances in the magnetic field are then used in simultaneous localisation and mapping (SLAM) to simultaneously build a map of the magnetic field and localise the device on it by Rao-Blackwellised particle filtering (Sequential Monte Carlo). The paper presenting this setup recently won the Best Paper Award at the International Conference on Information Fusion 2018.
