VerifiedBehavioral cloning simplifies the problem to supervised learning, but suffers from distribution shift, where differences between the state distributions at training time and execution time lead to error accumulation.78% similarUnverifiedDomain randomization can only cover error sources that the developer has already identified and explicitly modeled; once the real robot exhibits unmodeled factors, the policy is exposed to training blind spots.78% similarUnverified当标注不一致存在时，增加更多数据只会成倍放大混乱，向模型提供自相矛盾的监督信号77% similarUnverifiedBias introduced by a single defective data point can leak into seemingly unrelated capability dimensions, causing the model to simultaneously regress across multiple independent metrics such as deceptiveness, compliance, and risk aversion.76% similarUnverifiedBehavioral Cloning is susceptible to the compounding error problem, whereby minor deviations during policy execution accumulate continuously, causing the trajectory to deviate from the demonstration distribution.75% similar
