Author(s): Kieran Holland, Andreas Ipp, David I. Müller, and Urs Wenger Extracting continuum properties of quantum field theories from discretized spacetime is challenging due to lattice artifacts. Renormalization-group (RG)-improved lattice actions can preserve continuum properties, but are in general difficult to parameterize. Machine learning (ML) with gauge-equivari… [Phys. Rev.
