| # OpenHands Commit Noise Databases |
|
|
| This dataset contains commit-retrieval databases for 12 SWE-bench repositories at five noise ratios: 0%, 25%, 50%, 75%, and 100%. |
|
|
| Each archive expands to `noise_NNN/<repository>/` directories containing: |
|
|
| - `commits.db`: SQLite commit records |
| - `commits.faiss`: normalized inner-product FAISS index |
| - `commits.meta.jsonl`: FAISS row-to-commit metadata |
| - `commits.index_meta.json`: embedding and index configuration |
|
|
| The 0% archive is an exact file-level copy of the original database. The noisy datasets use deterministic nested selections with seed 42, so lower-ratio selections are subsets of higher-ratio selections. Of 644,099 planned noisy-field values, 175 generation gaps use the unchanged source field and are recorded in `source_fallbacks.json`. |
|
|
| The four generated ratios contain 323,850 commit rows each, including 322,072 indexed rows with a non-empty problem description. Embeddings use `BAAI/bge-large-en-v1.5` with dimension 1024, normalization enabled, and inner-product search. |
|
|
| Use `SHA256SUMS` to verify downloads. `database_validation_manifest.json` records exhaustive SQLite/JSON equality checks, FAISS counts, metadata checks, and database file hashes for the generated ratios. `noise_000_snapshot.json` records hashes for the original 0% files. |
|
|
| Extract an archive with: |
|
|
| ```bash |
| tar --zstd -xf commit_databases_noise_000.tar.zst |
| ``` |
