inverse-problems

I am using SimPEG.Utils.download for gpgLabs. The download messages are distracting in notebooks, so I wanted to suppress them. The option is controlled by "verbose=false", but it does not stop writing "Downloading ... Saved to:.." message.
Can verbose=false swtich kill all the print output?

Feature

The IRLS algorithm can handle L1 norm for the data misfit term as well as L1 norm for the model. However, in some scenarios users may want to have both terms together (problem with outliers in the data and sparse model in some domain). The IRLS algorithm can be adapted to handle this scenario by writing the L1-L1 functional as an augmented system of equations and solve it using the c

Suppose one chain is stuck on one mode; another on another mode. If those two chains may sample independently from each mode, the ESSs will be high when, really, they should be near zero since the samples don't represent anything like independently from the overall distribution. This is why multichain ESS makes sense and we should implement it. I feel like this will give a much better picture of t

Description of the desired feature:

Our forward models for the different geometries (points, prisms, tesseroids) allow to take multiple bodies as inputs, returning a single array as the resulting field generated by every one of these bodies on the computation points.
One of the properties of these forward models is their linearity: the resulting field for all the bodies should be equal to

Describe the bug
If eps_r is shape (N,) then the fields solved are shape (N,1)

Either:

• disallow 1-D eps_r arrays
  Or:
• keep track of eps_r shape and reshape the fields to match.
