ginokreis shares first results training UMI diffusion policies for cube stacking: v1, trained on human-speed demos collected 1.6x faster than teleop, achieved 91/100 success while running 2.4x faster than the teleop policy; v2, trained on demos slowed to teleop speed, reached 100/100. A follow-up thread covers ACT and delta policies.
