WebJan 4, 2024 · The second generates the timesteps and noise (as before), randomly sets a proportion p_uncond of sample labels to 1 and then calls the first method. The model will learn to ignore labels with a value of 1 because any sample can be part of the p_uncond batch. 2. That’s it. Our code can now do guided diffusion.

For the former, a classifier needs to be pre-trained. But I didn't find this pre-trained classifier in your code. I am a little confused if you are using the classifier-free guidance. ramsey adult school classesWebAug 22, 2024 · For classifier-free guidance, we need to do two forward passes: one with the conditioned input (text_embeddings), and another with the unconditional embeddings (uncond_embeddings). In practice, we can concatenate both into a single batch to avoid doing two forward passes. ...
