Researchers have found that metrics used to curate training data for AI policies do not necessarily improve the performance of those policies. In experiments on a pick-and-place benchmark, a metric that was highly effective at detecting defects actually resulted in the worst-performing policy. Conversely, a metric with lower defect detection accuracy produced a policy that was nearly as good as one trained on perfect data. The study also revealed that many metrics incorrectly use episode length as a proxy for defects, inflating their apparent accuracy. AI
IMPACT Highlights the need to evaluate data curation methods based on resulting policy performance rather than defect detection accuracy alone.
