Diffusion Model 的架构比较简单,采取的是 MLP 作为预测噪声的网络,timesteps = 500,加噪方式为 linear scheduler,epochs = 3000,batch_size = 512。本文在Fidelity、Utility、Synthesis和Privacy四个指标上对 Findiff、TVAE、CTGAN 和 TabDDPM 四种模型上做了测试,结果如下所示: 模型测试结果 可以看出,本文提出的...
# define operatord_dx=FinDiff(0,dx)# apply operatordf_dx=d_dx(f)# df_dx is now an array of the same shape as f containing the partial derivative The partial derivative , wherezmeans the 2nd axis, is d_dz=FinDiff(2,dz)df_dz=d_dz(f) ...

seemed to do that job. Not sure though, whether I am doing this correctly. Now the question is i dod have sqrt in my least squares operation. But why should it matter? It is not doing a closed form differentiation anyway. So for finite difference it should not matter at all. Right?
