Non-resonant new physics scenarios are relatively under-explored and may arise from off-shell effects or final states with significant missing energy. While targeted searches provide the greatest sensitivity to any particular target, it is important and complementary to pursue novel signal-agnostic searches. Specifically, non-resonant hadronic signals can result from a vast range of models with a large parameter space within each model. In this talk, I will discuss how to use weakly supervised anomaly detection strategies for non-resonant hadronic signals. The new methods are demonstrated using a semi-visible jet signature as a benchmark signal model, and are shown to automatically identify the anomalous events without specifying the signal ahead of time.
