Entropic, trim and BW are similar on training (BW is usually best).
Trim is better (more robust) than entropic on test.
Trim is sometimes better, but never much worse, than BW on test.
Annealed is always worse on train, but often best on test.
Annealed no-trim seems to be better than annealed+trim, and is 
probably the best overall.
