Low-Scaling Algorithm for Nudged Elastic Band Calculations Using a Surrogate Machine Learning Model
Autor: Jacob R. Boes, Martin Hangaard Hansen, Thomas Bligaard, Paul C. Jennings, José A. Garrido Torres
Publikováno v: Physical Review Letters. 122
We present the incorporation of a surrogate Gaussian Process Regression (GPR) atomistic model to greatly accelerate the rate of convergence of classical Nudged Elastic Band (NEB) calculations. In our surrogate model approach, the cost of converging t

Materials discovery is increasingly being impelled by machine learning methods that rely on pre-existing datasets. Where datasets are lacking, unbiased data generation can be achieved with genetic algorithms. Here a machine learning model is trained

Machine Learning Accelerated Genetic Algorithms for Computational Materials Search
Autor: Steen Lysgaard, Paul C. Jennings, Jens Strabo Hummelshøj, Thomas Bligaard, Tejs Vegge
A machine learning model is used as a surrogate fitness evaluator in a genetic algorithm (GA) optimization of the atomic distribution of Pt-Au nanoparticles. The machine learning accelerated genetic algorithm (MLaGA) yields a 50-fold reduction of req

Structures of small Ti- and V-doped Pt clusters: A GA-DFT study
Autor: Paul C. Jennings, Roy L. Johnston
Publikováno v: Computational and Theoretical Chemistry. 1021:91-100
High level GA-DFT searches are performed on small platinum clusters doped with early transition metal atoms, Ptx−yMy (M = Ti, V), where x = 2–6, y = 1, 2. Spin effects are studied and the global minimum structures are presented for the various sp

Electronic Properties of Pt–Ti Nanoalloys and the Effect on Reactivity for Use in PEMFCs
Autor: Paul C. Jennings, Bruno G. Pollet, Roy L. Johnston
Publikováno v: The Journal of Physical Chemistry C. 116:15241-15250
Theoretical investigations of Pt–Ti nanoparticles are presented using density functional theory (DFT) to study clusters up to sizes of 1.7 nm (201 atoms). Several compositions have been studied for varying sizes, and a projected density of states a
