SimPEG.directives.PGI_UpdateParameters#
- class SimPEG.directives.PGI_UpdateParameters(inversion=None, dmisfit=None, reg=None, verbose=False, **kwargs)[source]#
- Bases: - InversionDirective- This directive is to be used with regularization from regularization.pgi. It updates: - the reference model and weights in the smallness (L2-approximation of PGI) 
- the GMM as a MAP estimate between the prior and the current model 
 - For more details, please consult:
 - Attributes - verbose.debug has been deprecated. - Data misfit associated with the directive. - Inverse problem associated with the directive. - Inversion object associated with the directive. - Optimization algorithm associated with the directive. - Regularization associated with the directive. - Return simulation for all data misfits. - Return survey for all data misfits - fixed_membership - 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 inversion parameter(s) according to directive. - validate([directiveList])- Validate directive.
