Nudged elastic band calculations accelerated with Gaussian process regression

no code implementations14 Jun 2017 Olli-Pekka Koistinen, Freyja B. Dagbjartsdóttir, Vilhjálmur Ásgeirsson, Aki Vehtari, Hannes Jónsson

A Gaussian process model also provides an uncertainty estimate for the approximate energy surface, and this can be used to focus the calculations on the lesser-known part of the path, thereby reducing the number of needed energy and force evaluations to a half in the present calculations.

Minimum energy path calculations with Gaussian process regression

no code implementations30 Mar 2017 Olli-Pekka Koistinen, Emile Maras, Aki Vehtari, Hannes Jónsson

The calculation of minimum energy paths for transitions such as atomic and/or spin re-arrangements is an important task in many contexts and can often be used to determine the mechanism and rate of transitions.
