Masked mean pooling counts masked positions · case 04
Masked mean pooling counts masked positions.
Case contract
Return the coordinate mean over vectors with truthy mask values; no included vector returns an empty list.
Why this case matters
A small embedding preparation contract can be checked without a model or retrieval system.
