ML IREG
ML_IREG = [integer]
Default: ML_IREG = 2
Description: This tag specifies whether the regularization parameters are kept constant or not in the machine learning force field method.
The following cases are possible for this tag:
- ML_IREG=1: The (initial) precision (ML_SIGV0) and noise (ML_SIGW0) parameters are kept constant.
- ML_IREG=2: The parameters are optimized (default).
For the optimization of the noise parameter see this section.
