最终,如果我们将模型蒸馏到只剩下一个采样步,那么模型的输入就只是纯噪声\epsilon,此时信噪比为零,即\alpha_t = 0, \sigma_t = 1。在这种极端情况下,\epsilon预测和\mathbf{x}预测之间的联系完全中断:观测数据z_t = \epsilon不再包含\mathbf{x}的信息,并且\epsilon的预测\hat{\epsilon}_{\theta}(\mathbf...
The optical properties are associated with the interactions between light, electrons, and ions in the materials, which should be explained through the complex dielectric function,\(\epsilon (\omega )=\epsilon _1(\omega )+i\epsilon _2(\omega )\). Based on Fermi’s golden rule, one can der...

v = \alpha \epsilon - \sigma x z = \alpha x + \sigma \epsilon 我们的目标是要消去x,也就是x_0,因为这个在去噪时是不可知的。观察式子后,我们两个式子两边分别乘以\alpha,\sigma,得到: \alpha v = \alpha^2 \epsilon - \alpha \sigma x \sigma z = \alpha \sigma x + \sigma^2 \epsilon...
