The method infers the finite set of parameter transformations that preserve measurable physical magnitudes, without prior knowledge of the symmetry group or the mathematical relations between parameters and properties. Using a tailored multi-branch neural architecture and a symmetry-consistent loss, the study demonstrates versatility across examples in mathematics, nanophotonics, and quantum chemistry.","Finding discrete symmetry groups via Machine Learning  \nPablo Calvo-Barl´e􀀓, 1, 2 Ser􀀐io 􀀎􀀍 􀀌o􀀋ri􀀐o,1, 3 E􀀋uar􀀋o S´anchez-Burillo,4 an􀀋 Lui􀀓 Mart´􀀁n-Moreno1, 2, ∗ 1 Instituto de Nanociencia 􀀓 Materia􀀐es de Arag´on (INMA), CSIC-Universidad de Zaragoza, 50009 Zaragoza, Spain  \n2 Departamento de F´ısica de 􀀐a Materia Condensada, Universidad de Zaragoza, 50009 Zaragoza, Spain  \n3 Departamento de F´ısica Ap􀀐icada, Universidad de Zaragoza, 50009 Zaragoza, Spain  \n4 PredictLand S.
