Unverified当向量库中存在大量语义相近文档时，相似度分数趋于集中，导致Top-K召回结果区分度下降，即语义粘连问题57% similarUnverifiedWhen B is fixed and M increases, the bits allocated per fact decrease and distortion rises, which explains why feeding more data does not necessarily improve accuracy linearly.57% similarUnverifiedFloating-point addition does not satisfy the associative law; (a+b)+c and a+(b+c) may yield different results under floating-point precision.57% similarUnverifiedThe post hoc ergo propter hoc fallacy refers to the logical fallacy of inferring that A caused B solely because event B occurred after event A.57% similarUnverifiedThe researcher observed three divergence patterns: differences being absorbed and then converging, differences persistently leading to different outcomes, and divergence—reconvergence—divergence again.55% similar
