Vector retrieval: MMR repeatedly selects the top relevance score · case 03
MMR repeatedly selects the top relevance score.
Case contract
Rows [id,relevance,{other_id: similarity}]; choose max relevance - lambda*maximum similarity to selected IDs iteratively.
Why this case matters
An offline vector retrieval toy model isolates one ranking contract from embedding generation, storage, and serving.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| penalty changes second | ["a", "b"] | ["a", "c"] | Failed |
