Project: Accelerating End-to-End Deep Learning Reconstruction using Graph Neural Networks.

Currently, most of the machine learning based particle identification techniques developed by the CMS and ATLAS experiments rely on the inputs provided by the Particle Flow (PF) algorithms to convert detector level information to physics objects. Despite the very high reconstruction efficiency of PF algorithms, some physics objects fail to be reconstructed, reconstruct imperfectly or they exist as fakes. The end-to-end deep learning technique combines deep learning algorithms and low level detector representation of collision events. This project aims to implement graph neural network (GNN) based deep learning approaches to perform end-to-end tau identification. Furthermore, the developed GNN algorithm will be integrated with the existing CMS Software (CMSSW) based end-to-end deep learning framework (E2EFW).
