Generative diffusion models are all the rage, but it is unclear how they could be applied to sequences of varying numbers of events, e.g. tweets, reddit comments or taxi trips. We present a diffusion approach that turns any sequence into a noise sequence, a sample from a homogeneous Poisson process. Conversely, our model transforms such noise sequence samples iteratively into samples from any target data distribution by deleting events that it classifies as noise and proposing …
