EF-GAIfO learns to weight state-only demonstrations by comparing their transitions with transitions collected through the robot’s policy experience. A reconstruction model estimates similarity, and its reference broadens as experience grows. In point-mass tests, it outperformed GAIfO and WGAIfO; on a Unitree Go2, it achieved 80% success on random-target grasping and lifting in ten trials, a result limited to that task.
