class simpeg.directives.PGI_AddMrefInSmooth(inversion=None, dmisfit=None, reg=None, verbose=False, **kwargs)[source]#

Bases: InversionDirective

This directive is to be used with regularizations from regularization.pgi. It implements the strategy described in https://doi.org/10.1093/gji/ggz389 for including the learned reference model, once stable, in the smoothness terms.

Attributes

debug

verbose.debug has been deprecated.

dmisfit

finish()

Update inversion parameter(s) according to directive at end of inversion.

initialize()

Initialize inversion parameter(s) according to directive.

validate([directiveList])
