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

`dmisfit`	Data misfit associated with the directive.
`invProb`	Inverse problem associated with the directive.
`inversion`	Inversion object associated with the directive.
`opt`	Optimization algorithm associated with the directive.
`reg`	Regularization associated with the directive.
`simulation`	Return simulation for all data misfits.
`survey`	Return survey for all data misfits

DMtarget
phi_d_target

Methods

`endIter`()	Update inversion parameter(s) according to directive at end of iteration.
`finish`()	Update inversion parameter(s) according to directive at end of inversion.
`initialize`()	Initialize inversion parameter(s) according to directive.
`validate`([directiveList])	Validate directive.
