Lattice gauge equivariant convolutional neural networks

Institute for Theoretical Physics, TU Wien, Austria (Dated: December 25, 2020) We propose Lattice gauge equivariant Convolutional Neural Networks (L-CNNs) for generic machine learning applications on lattice gauge theoretical problems. At the heart of this network structure is a novel convolutional layer that preserves gauge equivariance while forming arbitrarily shaped Wilson loops in successive bilinear layers. We demonstrate that L-CNNs can learn and generalize gauge invariant quantities that traditional convolutional neural networks are incapable of finding. Gauge field theories are an important cornerstone of larger symmetry space is available [33]. This impressive result was transported along a given closed path.
