5v is what I am currently using as a baseline- it has an even smaller

--jesus-hidden-dim as 5t (hence faster to train), but gives the same

performance.

6g is a setup with a 'thinner' jesus-layer (with only one repeated-affine component)

and slightly more parameters, which is quicker to train than 5v but gives

about the same results. I'm hoping to use this setup, going forward.
