Researchers have developed a new framework to assess neural sensitivity beyond simple activation alignment. This approach uses local decodable information and Fisher information to measure a representation's ability to distinguish small perturbations under noise. The method, which summarizes representations using an expected projected pullback/Fisher metric, has been empirically shown to recover corresponding layers in independently trained neural networks and reveal differences between standard and robust training.
