ML_WTOTEN

From VASP Wiki

ML_WTOTEN = [real] 

Default: ML_WTOTEN = 0.005 if ML_IWEIGHT=1
= 1.0 otherwise

Description: This tag sets the weight for the scaling of the total energy in the training data within the machine learning force field method.


ML_IWEIGHT, ML_WTOTEN, ML_WTIFOR, ML_WTSIF form a group of tags which set the normalization and weighting of ab initio training data, i.e. energies, forces and stresses of the training structures. The main control tag is ML_IWEIGHT, please also have a look at its detailed description. If ML_IWEIGHT=1 the weight has a unit of eV/atom and is used to divide the data by it. For ML_IWEIGHT=2 and 3 the weights are unitless and the data is multiplied by the weight.
