论文摘要
我们介绍了多个粒子识别(MPID)网络,这是一种用于多个对象分类的卷积神经网络(CNN),由Microboone开发。 MPID提供$ E^ - $,$γ$,$μ^ - $,$π^\ pm $的概率和单个液体氩时间投影室(LARTPC)读数平面中的质子。该网络扩展了先前由微酮开发的单个粒子识别网络。 MPID作为输入作为输入的图像,要么围绕重建的相互作用顶点裁剪,要么仅包含连接到重建的顶点的活动,因此将工具从顶点查找和粒子聚类中的效率低下缓解。该网络是Microboone基于深度学习的$ν_e$搜索分析的重要组成部分。在本文中,我们介绍了网络的设计,培训和性能,以模拟和来自微生物检测器的数据。
We present the multiple particle identification (MPID) network, a convolutional neural network (CNN) for multiple object classification, developed by MicroBooNE. MPID provides the probabilities of $e^-$, $γ$, $μ^-$, $π^\pm$, and protons in a single liquid argon time projection chamber (LArTPC) readout plane. The network extends the single particle identification network previously developed by MicroBooNE. MPID takes as input an image either cropped around a reconstructed interaction vertex or containing only activity connected to a reconstructed vertex, therefore relieving the tool from inefficiencies in vertex finding and particle clustering. The network serves as an important component in MicroBooNE's deep learning based $ν_e$ search analysis. In this paper, we present the network's design, training, and performance on simulation and data from the MicroBooNE detector.
