这里,$\Omega$为 :eqref:`emmds`中$\mathcal{P}$的分母部分。直觉上,$\mathbb{E}\[\nu|\nu_{th}\]$越高,随机采样的$J$集合中包含的topk维度的概率就越大,从而模型效用就越好。因此,我们将$\mathbb{E}\[\nu|\nu_{th}\]$最高时的阈值确定为目标阈值$\nu_{th}^{\*}$,即:
|

|

$$
|

\nu_{th}^{\*} = \underset{\nu_{th}\in\[1, h\]}{\operatorname{argmax}} \mathbb{E}\[\nu|\nu_{th}\]

\nu_{th}^{\*} = \underset{\nu_{th}\in\[1, h\]}{\operatorname{argmax}} \mathbb{E}\[\nu|\nu_{th}\]
