Blindfolded Expert Data Boosts Imitation Learning

The author shares insights gained from a Technion paper on "blindfolded experts" regarding data collection.
- Core Finding: When collecting data for imitation learning, blindfolding the expert (or degrading their perfect vision) significantly improves task performance during the testing phase.
- Mechanism: This approach forces the imitator to explore and grasp the boundaries of success for a task, rather than simply memorizing the expert's flawless trajectory.
- Experimental Evidence: In highly challenging shape-insertion tasks, policies trained with non-blindfolded strategies suffered a massive drop in performance.
