For regression testing metrics, it is recommended to record exact match rate, key fact recall rate, refusal rate, and hallucination rate simultaneously; looking at multiple metrics together can avoid hidden degradation where the pass rate rises but answers become more conservative or more verbose.

UnverifiedThe deterministic equivalent expression for test error uniformly characterizes the interplay among factors such as sample size, covariance structure, model drift, regularization strength, and privacy noise.79% similarUnverifiedSignals for identifying overfitting include: the more strategy parameters the better; backtest results being extremely sensitive to small parameter changes; strategy performance dropping off a cliff in out-of-sample testing; and too few trades leading to insufficient statistical significance.79% similarUnverifiedA similarity threshold that is too high may cause valid answers to be incorrectly filtered out, while one that is too low may introduce noise, requiring a trade-off between recall and precision.78% similarUnverifiedLater checkpoints may have stronger similarity but can also overfit and respond poorly to prompts; earlier checkpoints are more flexible but may not have fully learned the identity features.78% similarUnverifiedThe researchers ruled out confounding factors such as prompt-wording noise and sampling confounds through multiple checks, and both findings (low decision sensitivity and high adversarial compliance rate) were replicated.78% similar
