Fig. 3From: Solving multiphysics-based inverse problems with learned surrogates and constraintsProjections onto increasing \(\ell _2\)-norm balls for the in- and out-of-distribution examples of Fig. 2. Top row: projections of in-distribution sample. Bottom row: projections of out-of-distribution sample. Each column corresponds to setting \(\alpha =0,0.1,0.2,0.4,1\) in Eq. 6Back to article page
