| # DeCoNav Dataset |
|
|
| This repository contains the complete compact DeCoNav task release, split into |
| 1,113 training tasks and 100 fixed evaluation tasks. It includes the task |
| annotations and compact evaluator trajectories required by the DeCoNav data |
| and evaluation pipeline. RGB/depth frame dumps, simulator scenes, debug logs, |
| and machine-specific files are intentionally excluded. |
|
|
| ## Splits |
|
|
| | Split | Tasks | Purpose | |
| | --- | ---: | --- | |
| | `train/` | 1,113 | DeCoNav training-task pool after excluding the fixed test tasks. | |
| | `test/` | 100 | Fixed task order used by the released DeCoNav evaluation. | |
|
|
| Each task directory contains: |
|
|
| ```text |
| single_config.json |
| collab_json/collab_config_00.json |
| success/trial_*/collab_00/task.json |
| ``` |
|
|
| The test directory names are identical to the original 100-task release. Some |
| training instructions occur in multiple scenes or source batches. Those |
| collisions receive a deterministic `.__batch_XX` suffix so that no task is |
| overwritten. `splits.json` records the original task name, source batches, |
| selected successful trial, file sizes, and SHA-256 hashes. |
|
|
| ## Download |
|
|
| ```bash |
| hf download Sunyao/deconav --repo-type dataset --local-dir assets/datasets/deconav |
| ``` |
|
|
| Use `assets/datasets/deconav/test` as the evaluator dataset directory. The |
| DeCoNav source release may pin an older immutable dataset revision for exact |
| paper-result reproduction; that revision remains available in repository |
| history. |
|
|
| ## Data Scope |
|
|
| - Simulator: Habitat-Sim |
| - Scene identifiers: HM3D v0.2 |
| - Scene files: not included |
| - Released modalities: JSON task annotations and compact trajectories |
| - Trial policy: preserve the original released trial for test tasks; use the |
| lexicographically latest successful trial for training tasks when multiple |
| successful trials exist |
|
|
| Evaluator-only positions, geodesic distances, and reference paths stored in |
| the compact trajectory are used only for initialization and metric |
| calculation. They are not policy inputs in the released DeCoNav evaluator. |
|
|
| ## Integrity |
|
|
| `DATA_SHA256SUMS` contains hashes for every task file. `splits.json` contains |
| the same per-file hashes plus split-level and whole-dataset tree hashes. Tree |
| hashes are computed from sorted UTF-8 lines of the form |
| `<relative_path>\t<size_bytes>\t<file_sha256>\n`. |
