Z-score anomaly detection loses sensitivity in the early stage of a traffic surge because σ is polluted, and in practice it is often combined with rate limiting to form a double defense line.

Unverified扩散模型通过逐步去噪的生成机制产生的频域异常比GAN更微弱且分布不规律，使传统基于频域分析或GAN指纹的检测方法效果大打折扣66% similarUnverifiedStochastic gradient descent (SGD) uses only one sample at a time, which is fast but produces noisy update directions.62% similarUnverifiedSparse rewards combined with long time spans cause gradient-based optimization signals to decay significantly during backpropagation.61% similarUnverifiedWhen ε ≈ 1, the gradient second-moment term in the denominator is diluted, adaptive scaling has almost no effect, and the optimizer behaves close to pure SGD.60% similarUnverified改写攻击（paraphrasing）能有效削弱水印，因为它改变了token选择，降低绿名单token比例，使z-score回落到检测阈值以下60% similar
