ML CDOUB: Difference between revisions

Latest revision as of 14:37, 19 October 2023

Default: ML_CDOUB	= 4.0	for `ML_MODE = select`
	= 2.0	else

Description: This tag controls the criterion for "enforced" DFT calculations within the machine learning force field method.

The usage of this tag in combination with the learning algorithms is described here: here.

If at any time, the estimated force errors are ML_CDOUB times larger than the Bayesian threshold (i.e. "critically" high), a first principles calculation is performed and a new force field is immediately generated (even if the counter for sampling is below the minimum amount of sampled structures ML_NMDINT).

-This flag is applied in the case of {{TAG|ML_FF_ISAMPLE}}=2. In that case if the estimated error is {{TAG|ML_FF_CDOUB}} times larger than the threshold ({{TAG|ML_FF_CSF}} for the spilling factor and {{TAG|ML_FF_CTIFOR}} or it's updated value form {{TAG|ML_FF_LCRITERIA}}=''.TRUE.'' for the Bayesian error), the sampling is stopped and a new force field is generated.
