In #465, we implement RS2 sampling, which does not need any information from the forward pass. However, the actual training data in RS2 changes each epoch, which the selector currently does not support. We fitted the implementation to the downsampling case, but actually it might be better to extend the selector component to allow updating the TTS if no information from model forward pass is required, since the definition of downsampling more or less is using information from the forward pass.
