ML_SIGW0

ML_SIGW0 = [real]
Default: none 

Default: ML_SIGW0	= 1E-7	for ML_MODE = REFIT
	= 1.0	else

Description: This flag sets the precision parameter $s_{\mathrm{w}}$ for the fitting in the machine learning force field method.

If the regularization needs to be controlled manually, like e.g. in the fitting via singular value decomposition (ML_IALGO_LINREG=4), the best is to control the regularization via this parameter and keep the noise paramter $s_{\mathrm{v}}$ (see ML_SIGV0) constant at 1.

For the theory of this regularization parameter see this section.
