Thank you for your contribution, but I can't make sense of the three curves in Figure 3.

[Supzekun]

Curve 1: Figure III left (Signal-to-noise ratio (SNR) of linear and cosine noise schedules for reference.) The relationship is given in your paper:

However when I use linear schedule locally, Diffusion Steps = 1000, and SNR by Equation 4, the curve is like this:

Curve 2: Figure III right（Weights of P2 weighting and the baseline with a linear schedule.）The relationship is given in your paper:

However when I use linear schedule locally, Diffusion Steps = 1000, and SNR by Equation 4, weight by and P2-weight by set k = 1, γ =1. Also, I understand that you used the normalization operation: so I scaled weight to a range of 0 to 1 by maximum and minimum values However, the curve I get is this:

These curves do not match at all the results you gave in your paper, did I do any step wrong? I am very interested in this article and look forward to your reply, thanks!
