Near Optimal Stratified Sampling

Jul 26, 2019
Tiancheng Yu, Xiyu Zhai, Suvrit Sra

* We have discovered a mistake in the main result. The quantity on the RHS of (3) is not equal to the variance of estimator (2) when the sampling rule is designed adaptively as we do. There will be further cross-product terms which are now dominant terms. Therefore, although our bound is correct for (3), it no longer implies bound of the variance of (2)
