Potential speedups

• We can condition on “parts” of each draw of the sampler, in particular if we condition on the projection of the rejection sample - center onto direction then resampling on the ray can be sped up for some things like LASSO. Could be some cost in power.

• Learning a higher dimensional function can perhaps save some time – proper conditioning has to be checked.
