DESCRIPTION:I will report on our efforts to apply machine learning techniq
 ues to the problem of describing the behaviour of atoms. For a number of a
 toms at given positions\, quantum mechanics gives an expression for the to
 tal energy and hence the forces on every atom. The calculation of this ene
 rgy is extremely expensive\, and a minor industry exists that tries\, with
  limited success\, to model the energy function using oversimplified empir
 ical interatomic potential functions (e.g. Lennard-Jones potential) which 
 can be evaluated very quickly. We try to bridge the 8 orders of magnitude 
 speed gap between the methods\, while maintaining the accuracy of quantum 
 mechanics.
