PhD in Inverted Neural Networks for Optimizing Permanent Magnet Structures

jobbeskrivelse:

Can inverted neural networks (NN) be used for optimizing permanent magnet structures? Can key properties such as magnetic field homogeneity, field magnitude and magnetic forces be assessed by an NN? If so, we may be able to open up a new area of research where creative artificial intelligence (AI) is used for making novel designs rather than using traditional and tedious optimization algorithms while at the same time clearing the path for designs and solutions hitherto un-thought of by humans.

This will have a huge impact not only on magnet design, but also on any other design problem where simple fundamental building blocks combine to a complex solution. The PhD project will be focused on applying an existing numerical model of magnetostatics for training NNs, using these for predictions and then go for inverting the NNs in order to get novel/creative solutions to permanent magnet optimization challenges.

This PhD position at DTU Energy is a part of a unique research project called AiMADE (http://www.aimade.org/) where we exploit artificial intelligence to solve problems related to energy technologies. We will study the use of neural networks for optimizing permanent magnet structures by realizing a novel and fast computational model build on an existing computational framework for magnetic field calculations and written in Fortran.

Your role as a PhD student will be to investigate the possibility of training neural networks, or other AI-related approaches, on various magnet configurations modelled with our in-house code. Once trained and the system has reached an acceptable level of recognizing hitherto unseen structures for their key-properties (field magnitude, homogeneity etc.) you will work on inverting the system in order to reach predictive capability. You will be asking the neural network how a magnet configuration should look like when specifying a certain goal. You will be working together with other PhD students that also use this code / framework for other magnetism related problems and will thus from the beginning of the project enter into a group of young people with similar interests and technical challenges.

The main activity will take place at the Department of Energy Conversion and Storage at DTU Risø campus initially and from ultimo 2019 at DTU Lyngby campus, as the department is being united at this campus.
