| # code2lora-data-smartcap — smart-capped GRU training QnAs |
|
|
| Smart-capped, file/function-balanced per-commit QnA dataset used to train |
| **Code2LoRA-GRU** in the paper. The capping reduces the heavy-tailed |
| training distribution by: |
|
|
| 1. Dropping trivial targets (`len(target.strip()) < 4`, bare `")"`, etc.). |
| 2. Round-robin sampling within each commit across (test_file, test_function) |
| groups so file/function diversity is preserved. |
| 3. Capping each commit at `max_per_commit = 8` and each |
| (commit, test_file) at `max_per_file = 4`. |
| |
| **Only `in_repo_split == "train"` rows are capped.** Val and test rows |
| pass through verbatim, so evaluation suites remain comparable to the |
| uncapped dataset. |
| |
| ## Counts |
| |
| | File | Rows | Notes | |
| |---|---:|---| |
| | `qna/cr_train.parquet` | 1,187,359 | 215,129 capped train + 437,227 val + 535,003 test (val/test untouched) | |
| | `qna/cr_val.parquet` | 641,848 | full uncapped | |
| | `qna/cr_test.parquet` | 476,455 | full uncapped | |
|
|
| ## Split semantics |
|
|
| Two independent split axes: |
|
|
| * `cross_repo_split ∈ {train, cr_val, cr_test}` -- which **repositories** the model has seen. |
| * `in_repo_split ∈ {train, val, test}` -- chronological 80/10/10 split of each repo's **commits**. |
|
|
| The four evaluation suites used in the paper map onto these axes as follows: |
|
|
| | Paper suite | File | Selection | |
| |---|---|---| |
| | Train (loss) | `qna/cr_train.parquet` | `in_repo_split == "train"` | |
| | IR val | `qna/cr_train.parquet` | `in_repo_split == "val"` | |
| | IR test | `qna/cr_train.parquet` | `in_repo_split == "test"` | |
| | CR val | `qna/cr_val.parquet` | all rows | |
| | CR test | `qna/cr_test.parquet` | all rows | |
|
|
| All evaluation suites use the **full uncapped** assertion set. Only the in-repo train loss path is smart-capped (see `code2lora/code2lora-data-smartcap`). |
|

| ## Companion datasets |
|
|
| * `code2lora/code2lora-data-commits` per-commit metadata + diff embeddings |
| * `code2lora/code2lora-data-snapshots` direct-projection (static) variant |
