一类新的分层抽样模型的期望$L_2-$偏差界

Expected $L_2-$discrepancy bound for a class of new stratified sampling models

Jun Xian, Xiaoda Xu

摘要:

引入了一类凸等体积分拆。在这些分区下讨论预期的$L_2-$差异。有两个主要结果。首先,在这种划分下,我们生成的随机点集具有较小的期望$L_2-$差异比经典的抖动采样相同的采样数。其次,给出了这种划分下的$L_2-$偏差上界的一个明确的期望上界。此外,在这些新的分区中,存在最优的预期$L_2-$差异上界。

英文摘要:

We introduce a class of convex equivolume partitions. Expected $L_2-$discrepancy are discussed under these partitions. There are two main results. First, under this kind of partitions, we generate random point sets with smaller expected $L_2-$discrepancy than classical jittered sampling for the same sampling number. Second, an explicit expected $L_2-$discrepancy upper bound under this kind of partitions is also given. Further, among these new partitions, there is optimal expected $L_2-$discrepancy upper bound.
