If you have a question about this talk, please contact Dr Hannah Price. There is much interest currently in the potential of machine learning to tease useful information out of complex data on materials. Here I ask whether this can work when only experimentally accessible data, i.e. averages rather than microstates, are available. I will use Principal Component Analysis to study simulated neutron-scattering data on cluster quantum magnets [1] and experimental muon-spin relaxation curves from various superconducting and magnetic materials [2]. While the algorithms can perform certain functions, such as detection of phase transitions, automatically, I will argue that their best use is in providing human scientists with new ways to look at the data – an approach that has come to be known as “augmented”, rather than “artificial”, intelligence.
