[CP2K-user] Machine Learning Force Fields

[Nicklas Österbacka]

n2p2 <https://compphysvienna.github.io/n2p2> implements 
Behler-Parinello-style neural network potentials. There is also a plugin 
for the MD package QUIP that implements Bartók's kernel-based Gaussian 
Approximation Potential <https://libatoms.github.io/GAP/>.

There are plenty more, but those two should give you something to test 
things out with and are code-agnostic. You do have to prepare the data set 
for training, however. Writing a script to do so should not be particularly 
difficult.

Good luck,
Nicklas
