• J. Mills, F. Yu, T. Wongjirad with the MicroBooNE Collaboration. Cosmic muon identification and rejection using a sparse Mask-RCNN Convolutional Neural Network. Journal of Instrumentation 17 (2022) 09, P09015. (arxiv:2201.05705)
  
  Describes the development of an object-detection network that is able to put boxes around cosmic muon interactions and neutrino interactions in MicroBooNE images. An advance in the technique is to use sparse submanifold convolutions in order to speed up runtime and deploy on CPUs. Also shown is how one can use the network to improve upon cosmic rejection when combined with the currently deployed method on MicroBooNE.
  
• Abratenko, K. Mason, J. Mills, R. Sharankova, T.M. Wongjirad with the MicroBooNE collaboration. “Search for an anomalous excess of charged-current quasi-elastic νe interactions with the MicroBooNE experiment using Deep-Learning-based reconstruction.” Physical Review D 105.11 (2022): 112003. arXiv:2110.14080
  
  Describes an analysis investigating the MiniBooNE low energy excess anomaly. Did not see an excess of events over expectation. If anything, data is consistent with a somewhat low rate.

  Describes the shower reconstruction used in our analysis looking at low-energy electrons. Discusses how we checked the method for estimating the energy of showers using showers from neutral pion photons and from electrons made during muon decay.
  
• Abratenko, K. Mason, J. Mills, R. Sharankova, T.M. Wongjirad with the MicroBooNE collaboration. Semantic Segmentation with a Sparse Convolutional Neural Network for Event Reconstruction in MicroBooNE. Physical Review D 103, 052012 (2020) (arXiv:2012.08513)
  
  Describes the deep convolutional neural network developed to label individual pixels of images containing neutrino interactions from MicroBooNE. The advancement here is the use of sparse-submanifold convolutions which allowed us to deploy the network on the existing CPU infrastructure at Fermi National Lab.
  
• P. Lutkus, S. Aeron, and T. Wongjirad. Towards Designing and Exploiting Generative Networks for Neutrino Physics Experiments using Liquid Argon Time Projection Chambers. International Conference on Learning Representations (ICLR) 2021 workshop on Deep Learning and Simulations. (arxiv:2204.02496)
  
  Describes our attempts to generate LArTPC-like images using a Vector-Quantized Variational Autoencoder or VQ-VAE, a type of generative network. We also introduce the use of Semantic Segmentation as a tool for evaluating image quality.
