9/30/2022The goal The goal of my ECA was to develop a scalable, high quality machine-learning-based data reconstruction method for neutrino experiments that utilize Liquid Argon Time Projection Chamber detectors, or LArTPCs in short, including the Short Baseline Neutrino program and Deep Underground Neutrino Experiment. ~~## Reco chain in a nutshel Steps of physics data reconstruction is naturally hierarchical: starting from a low-level signal processing, identification of indibidual particle trajectories, inference of particle-level information, then finally event-level information inferred from correlations between multiple particles. ~~ Progress in the past A full reconstruction chain has been completed by the end of the 3rd year. In this 4th year, we have introduced capabilities to quantify calibrated uncertainties for key physics outputs. Just like a traditional reconstruction method, the chain consists of multiple modules of ML algorithms that perform individual reconstruction tasks. The whole chain combines these algorithms in a hierarchical manner based on domain physics knowledge. The full chain was presented at the NeurIPS workshop for physical science in 2020, and individual algorithms have been published in multiple PRD papers. Some of them received editor's pick and DOE science highlights. Accessible research
8/25/2022Run the full reconstruction chain. Modify the config to train U-ResNet + PPN only. Run as long as possible on a100 gpu. Plot the loss curve (while training is ongoing). Save weights every 1000 steps. Run the inference on 32000 samples per saved weights to make a validation accuracy plot. Show (train loss and validation loss) in an overlay. Learn how to run particle bomb event generator + DUNE-ND geant 4 (edep-sim) and detector simulation larnd-sim.
11/1/2021Reconstruction related Software for production Scalable software for distributing the execution of a reconstruction pipeline to thousands of GPUs. Targetting by the end of 2021 (300,000 A100 GPU hours allocated at the Polaris HPC cluster). Optimization of the chain Benchmark the quality of labels at edepsim level + reproduce the performance in the paper Implement an event generator used to train the chain in edepsim (Andrew Morgan)
