FA-99402 / Embedding vector normalization / Member archive
Batch normalization scales by the entire batch norm · case 02
Batch normalization scales by the entire batch norm.
Case contract
Return same-shaped rows independently L2-normalized; zero rows stay zero; empty batch stays empty.
Why this case matters
A small embedding preparation contract can be checked without a model or retrieval system.
