单词	invariance
释义	invariance noun in·​vari·​ance (ˌ)in-ˈver-ē-ən(t)s  : the quality or state of being invariant Example Sentences Recent Examples on the Web The original Laughlin's pump argument, which used adiabatic evolution and gauge invariance to deduce a return to the original state of the system after one cycle, did not work with QAC. Spyridon Michalakis, Scientific American, 1 Aug. 2020 After each cycle, the quantum system would return to its original state as the result of a phenomenon known as gauge invariance. Spyridon Michalakis, Scientific American, 1 Aug. 2020 Violating these conditions — called charge and parity invariance, C and P for short — would cause matter and antimatter to act differently. Dennis Overbye, New York Times, 15 Apr. 2020 The secret to the link is in modularity and invariance in the equations representing the curves. Caroline Delbert, Popular Mechanics, 2 Mar. 2020 Noether showed that the symmetries of general relativity — its invariance under transformations between different reference frames — ensure that energy is always conserved. Quanta Magazine, 26 June 2019 The nesting-doll feature — called discrete scale invariance — arose from a symmetry in the equation describing the forces between three particles. Quanta Magazine, 27 May 2014 LeCun tells Science that translational invariance, too, could eventually emerge on its own with better general learning mechanisms. Matthew Hutson, Science | AAAS, 24 May 2018 Translational invariance is the principle behind convolutional neural networks, or convnets, LeCun's greatest claim to fame.
