FA-99397 / Embedding vector normalization / Member archive
Epsilon normalization adds epsilon to every coordinate divisor · case 02
Epsilon normalization adds epsilon to every coordinate divisor.
Case contract
Divide a vector by max(L2 norm, positive epsilon); zero and empty vectors return all-zero shape.
Why this case matters
A small embedding preparation contract can be checked without a model or retrieval system.
