Description

Limited by the lack of truth labels on real data, fully supervised ML algorithms are constrained to training only with simulated samples. With self-supervised learning, we can leverage vast amounts of unlabeled real data to facilitate training. We investigate the application of VICReg, a contrastive learning model, on a classification task: discriminating signal jets (e.g. $H \rightarrow b \bar{b}$ jets) from background jets (e.g. QCD jets). We also explore the use of jet augmentations in contrastive learning.
