Project description

Earlier this year, the Spin Dynamics group at the University of Southampton created a family of neural networks that recovered molecular distance distributions from magnetic spectroscopy data (DOI: 10.1126/sciadv.aat5218). The networks reliably returned distance data for proteins, nucleic acids, photosynthetic reaction centres, and other systems of current chemical and biological interest. The principal problem is that... this was not supposed to be possible: the mathematical transformations in question are ill-posed and numerically unstable. At the moment, we have no slightest idea how those neural networks accomplish what is technically, without regularisation, an impossible mathematical operation.

The objective of this project is to find out. It will make use of one of the biggest supercomputers in the UK to run neural network training against quantum mechanical simulations of spin dynamics in biological systems. The resulting networks will be taken apart with the purpose of finding out how exactly they work. The conclusions will have significance across physical sciences - at the moment, the internal functioning of artificial neural networks is largely a mystery.

It is likely that the student will make a major contribution to both quantum theory and artificial intelligence by exploring, developing, and analysing neural networks that process spectroscopic data. This project is a collaboration with ETH Zurich (Prof Gunnar Jeschke) and Weizmann Institute (Prof Daniella Goldfarb), and will involve visits to both of these institutions.
