simpeg.directives.PGI_UpdateParameters#

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

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
