UnverifiedReverse mode automatic differentiation can obtain gradients of the loss with respect to all parameters in a single backward pass, with complexity only a constant multiple of the forward computation (typically 2–4×).66% similarUnverifiedThe study points out that aggregated accuracy metrics systematically obscure asymmetric capabilities in multilingual factual reasoning, which is a manifestation of Simpson's paradox.65% similarUnverifiedFor dissipative systems where time evolution is irreversible, backward reconstruction is an ill-posed problem, and in the strongly dissipative limit the round-trip consistency signal may become unreliable.65% similarUnverifiedThe root cause of the rare disease detection paradox lies in imbalanced datasets: when positive samples are extremely scarce, false positives severely distort predictions.62% similarUnverifiedThe researcher observed three divergence patterns: differences being absorbed and then converging, differences persistently leading to different outcomes, and divergence—reconvergence—divergence again.61% similar
