The Loss Surface of XOR Artificial Neural Networks
Dhagash Mehta, Xiaojun Zhao, Edgar A. Bernal +1
Training an artificial neural network involves an optimization process over the landscape defined by the cost (loss) as a function of the network parameters. We explore these lands…
Tunneling-splittings from path-integral molecular dynamics using a Langevin thermostat
C L Vaillant, D J Wales, S C Althorpe
We report an improved method for the calculation of tunneling splittings between degenerate configurations in molecules and clusters using path-integral molecular dynamics (PIMD).…
Exotic Bilayer Crystals in a Strong Magnetic Field
William N. Faugno, Alex J. Duthie, David J. Wales +1
Electron bilayers in a strong magnetic field exhibit insulating behavior for a wide range of interlayer separation for total Landau level fillings , which has been i…
From Sticky-Hard-Sphere to Lennard-Jones-Type Clusters
Lukas Trombach, Robert S. Hoy, David J. Wales +1
A relation between the set of non-isomorphic sticky hard sphere clusters and the sets of local energy minima $…
