DIfference in model architecture
During the development phase, there were subtle changes in the architecture of ScIDiff. An important one is the suppresion of a "redundant" activation layer in the convolutional block, which is part of the time embedding module. See this commit. Therefore, there are some experiments that, in order to be replicated, need to revert this change; in particular, for the experiment with the linear schedule and 50 diffusion steps (model date: 20200720, model_id: 0000001)
