SimPEG.directives.InversionDirective#
- class SimPEG.directives.InversionDirective(inversion=None, dmisfit=None, reg=None, verbose=False, **kwargs)[source]#
Bases:
object
Base inversion directive class.
SimPEG directives initialize and update parameters used by the inversion algorithm; e.g. setting the initial beta or updating the regularization.
InversionDirective
is a parent class responsible for connecting directives to the data misfit, regularization and optimization defining the inverse problem.- Parameters:
- inversion
SimPEG.inversion.BaseInversion
,None
An SimPEG inversion object; i.e. an instance of
SimPEG.inversion.BaseInversion
.- dmisfit
SimPEG.data_misfit.BaseDataMisfit
,None
A data data misfit; i.e. an instance of
SimPEG.data_misfit.BaseDataMisfit
.- reg
SimPEG.regularization.BaseRegularization
,None
The regularization, or model objective function; i.e. an instance of
SimPEG.regularization.BaseRegularization
.- verbosebool
Whether or not to print debugging information.
- inversion
