超参数问题 #1

Closed willcococv closed 2 weeks ago

感谢作者的工作，仔细阅读代码之后有个问题想请教一下： 在通过超参数计算weight的时候，是出于什么样的考虑通过 2rho-1、2alpha-1进行范围调整的？self.max_sigma的引入是出于什么样的考虑？谢谢 image

Thanks for your interests.

  1. Adjust the range of the LUT output from [0,1] to [-1,1].
  2. Avoid divergence with a manual bound for division.
