The PhD position is part of the European Training Network ‟ELO-X – Embedded Learning and Optimization for the neXt generation of smart industrial control systems”. ELO-X will recruit altogether 15 PhD fellows at 6 research universities and 5 international companies from 5 European countries, who will meet regularly during exchange visits, training events, workshops, and summer schools organized by the network.
This position at University of Freiburg has a strong methodological focus in the fields of deep learning and learning-based control. The position is based at the Neurorobotics Lab headed by Prof. Joschka Boedecker. The aim is the development of advanced, scalable, uncertainty-aware learning-based control methods and open-source software, as well as their application to industrially relevant optimization and estimation problems. While these methods are generic and applicable in several branches of engineering, they shall be tested and used in close cooperation with the the other ELO-X PhD fellows, in particularly with those who are based at ETH Zurich, KU Leuven, and Robert Bosch GmbH during mutual exchange visits of several months duration.
PhD Project Description
PhD Project: Bayesian Deep Learning for Embedded MPC.
Deep Learning has brought significant progress in a variety of applications of machine learning in recent years. As powerful non-linear function approximators, their potential for use in learning-based control applications is very appealing. They benefit from large amounts of data, and present a very scalable solution e.g. for learning hard-to-model plant dynamics from data. Currently, the most widely- used method of training these deep networks are maximum likelihood approaches, which only give a point estimate of the parameters that maximize the likelihood of the input data, and do not quantify how certain the model is about its predictions. The uncertainty of the model is, however, a crucial factor in robust and risk-averse control applications. This is especially important when the learned dynamics model is to be used to predict over a longer horizon, resulting in compounding errors of inaccurate models. Bayesian Deep Learning approaches offer a promising alternative that allows to quantify model uncertainty explicitly, but many current approaches are difficult to scale, have high computational overhead, and poorly calibrated uncertainties. The objective for the ESR in this project will be to develop new Bayesian Deep Learning approaches, including recurrent architectures, that address these issues and are well suited for embedded control applications with their challenging constraints on computational complexity, memory, and real-time demands.
Timeline and remuneration:
The ideal starting time is in early summer 2021. The PhD projects last for the duration of three years, and are carried out at the Neurorobotics Lab at the University of Freiburg, Germany. The PhD years include at least one longer visit – a so-called ”secondment” – between one and six months to another group in the ELO-X network, depending on the project needs and the scientific interests of the PhD fellows. The first year is mainly dedicated to studying and getting acquainted with the relevant state of the art in Bayesian Deep Learning, NMPC, and methods for scalable learning-based control. The second year focuses on development and benchmarking of optimized Bayesian Deep Learning models that can be evaluated fast, have small memory footprint, and are well calibrated to enable high-performance, robust MPC applications. In the third year, the plan is to focus on open-source software implementation, algorithm verification and integration into rapid prototyping frameworks for embedded control systems. A fourth PhD year can be added and funds are reserved for this at the University of Freiburg. The remuneration is generous and will be in line with the EC rules for Marie Curie grant holders. It consists of a salary augmented by a mobility allowance, resulting in a net monthly salary of about 1900-2300 Euro depending on family status.
