我们推导出 Orlicz 范数失真下量化问题的高分辨率公式。在此设置中,最佳点密度解决了一个变分问题,该问题包含一个函数 g:ℝ+→[0,∞),表征底层 Orlicz 空间的量化复杂度。此外,渐近最优密码本引发了一系列紧密的经验测量。可能的累积点集被表征,并且在大多数情况下它由单个元素组成。在这种情况下,我们会发现与经典环境中一样的收敛性。
We derive a high-resolution formula for the quantization problem under Orlicz norm distortion. In this setting, the optimal point density solves a variational problem which comprises a function g:ℝ+→[0,∞) characterizing the quantization complexity of the underlying Orlicz space. Moreover, asymptotically optimal codebooks induce a tight sequence of empirical measures. The set of possible accumulation points is characterized, and in most cases it consists of a single element. In that case, we find convergence as in the classical setting.
