Three level mixed norm inverse solutions

Open jshanna100 opened this issue 3 years ago • 2 comments

Is mixed norm L212 source localisation i.e. optimising for spatially distinct, sparse solutions across multiple experimental conditions (described in Gramfort et al, 2012) implemented in MNE yet?

Ok, maybe a naive question, but could this be implemented straightforwardly within the existing Block Coordinate Descent algorithm by swapping out the L21 proximal operator with the L212 proximal operator, and also for the duality gap calculation?
