class simpeg.directives.JointScalingSchedule(warmingFactor=1.0, chimax=10000000000.0, chimin=1e-10, update_rate=1, **kwargs)[source]#

Bases: InversionDirective

For multiple data misfits only: rebalance each data misfit term during the inversion when some datasets are fit, and others not using the ratios of current misfits and their respective target. It implements the strategy described in https://doi.org/10.1093/gji/ggaa378.

Attributes

chimax

Maximum chi factor.

chimin

Minimum chi factor.

debug

verbose.debug has been deprecated.

dmisfit

Data misfit associated with the directive.

invProb

Inverse problem associated with the directive.

inversion

Inversion object associated with the directive.

mode

The type of update to perform.

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

update_rate

Will update the data misfit scalings after this many iterations.

verbose

Whether or not to print debugging information.

warmingFactor

Factor to adjust scaling of the data misfits by.

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.
