The key observation of Score Centering is that the drift term originates from the nonzero expectation of the score function under Q, so subtracting that expectation exactly cancels it without affecting the covariance signal.

UnverifiedScore Centering reduces the variance of gradient estimates by applying mean subtraction to the score function.77% similarUnverifiedScore Centering does not attempt to eliminate engineering differences (quantization, asynchrony, etc.) but mathematically compensates for their effect on the gradient, so it applies to all the above types of mismatch.71% similarUnverifiedA reasonable prediction loss combined with 0% downstream control accuracy is highly consistent with representation collapse, meaning the encoder has fooled the self-supervised objective without learning any useful dynamic information.69% similarUnverified从回报中减去任何不依赖于动作的基线函数b(s)不会改变梯度估计的期望值但可以降低方差69% similarUnverifiedIn the scoring formula, unknown states should be removed from the denominator, so that the less known information there is, the more conservative the score rather than the more random.69% similar
