The video is here. https://catalog.caida.org/details/media/2022_jitterbug_pam/resources The code is on GitHub (https://github.com/estcarisimo/jitterbug). I am happy to help if you want to try it on your dataset. Applying the method to all the data that we have is an option, as it is computationally expensive to run. But we currently don't have a concrete next step for this project (the funding for this was gone). We barely keep the data (MANIC) collection going at this stage.
