Description

This talk presents a summary of our tested anomaly detection models. We are studying the performance of two approaches on the LHC Olympics datasets, one based on Adversarial Autoencoders and the other using a Normalizing Flows method (arxiv:2003.13913). Combining those methods with traditional “bump-hunting” algorithms (​https://github.com/lovaslin/pyBumpHunter​) , we attempt to uncover the mysteries of the LHCO Black boxes.
