Conditional Unet using dataset with one scalar label

[HangilY]

Hello,

I am PhD candidate at SNU.

Your repo helped me really good understanding DDPM.

And i want to change this code to train a image labeled by 1 scalar value.

Is there any respository or your comment that i can reference?

thank you very much.

Hey you. By a scalar you mean a continuous value within a certain range? That's an interesting question. One thing you could try is normalizing your scalar between 0 and 1 and learn an one dimensional embedding which you multiply the scalar with. Maybe even learning 2 embeddings and linearly interpolating between these two. Or you could think of discretizing your scalar and then learning an embedding for each discrete representation.
All of these should be quite easy to implement in the current codebase.
Does that help?

Thanks!

1. Yes continuous value within a certain range.
2. Thank you, actually i was trying to embed a one dimensional tenser with value 'c'. And the got the error "RuntimeError: Expected tensor for argument Big Refactor #1 'indices' to have one of the following scalar types: Long, Int; but got torch.cuda.DoubleTensor instead (while checking arguments for embedding)"
   Maybe the data type is not compatible i guess.
   I am still working on it :D. Thanks.
3. discretizing is also a good idea and i have tried it on GAN generative model and it was good.

Thank you it helped me :D

Thanks Dome.

I have change the code and it's doing good so far.

I have to validate data after training but the training process is working now.

These are things that i have changed:

1. CustomDataset Loader
2. Image size
3. Embedding of Label. ( I have made a tensor dimension of t, "t = self.pos_encoding(t, self.time_dim)" and filled with a scalar label value

thanks
