| # Setup for local source processing |
|
|
| This directory contains the shared download and image/video conversion helpers |
| used by the six recipe-only directories under `sample/`. Their source data and |
| generated records are not distributed by this repository. |
|
|
| Use Python 3.10 or later. From the directory containing `MMTA-v1.0/`, install |
| the dependencies: |
|
|
| ```bash |
| python -m pip install -r MMTA-v1.0/processing/requirements.txt |
| ``` |
|
|
| Install `ffmpeg` and `ffprobe` for video processing. Credentialed PhysioNet |
| downloads also require `wget` and an interactive terminal. |
|
|
| | Domain | Download and generation instructions | |
| |---|---| |
| | MIMIC mortality | [mimic_death](../sample/image-timeseries/mimic_death/README.md) | |
| | MIMIC discharge | [mimic_disch](../sample/image-timeseries/mimic_disch/README.md) | |
| | PixelRec | [pixelrec](../sample/image-timeseries/pixelrec/README.md) | |
| | SP500 / FinMultiTime | [sp500](../sample/image-timeseries/sp500/README.md) | |
| | CoVLA | [covla](../sample/video-timeseries/covla/README.md) | |
| | CUHK-X HAR | [cuhk_x_har](../sample/video-timeseries/cuhk_x_har/README.md) | |
|
|
| Complete each upstream source's access requirements with your own account before |
| downloading. `download.py --dry-run` prints a plan without contacting a source or |
| writing data; actual downloads require `--accept-terms`. Use `--help` on each |
| domain's `download.py` and `generate.py` to inspect all available options. |
| Downloaded archives must be unpacked before building. |
|
|
| Keep source data and outputs outside `MMTA-v1.0/`, for example in sibling |
| `local_sources/` and `local_work/` directories. Generation writes a new domain |
| directory containing task JSONL, sensor CSVs and intermediate prompts. Video |
| recipes also write cropped videos; image recipes reference the local source |
| images rather than copying them. Generated paths are relative to that local |
| domain directory, and can refer to source images outside it. |
|
|
| `common/local_generation.py` orchestrates the per-domain builders and the common |
| converters. Optional `--input-jsonl` skips source prompt construction for all |
| recipes except SP500, which rebuilds inputs using source-dated news strictly |
| before the forecast cutoff. MIMIC discharge also uses the table, bucketing and |
| splitting helpers in `sample/image-timeseries/mimic_death/`; retain both MIMIC |
| directories when copying scripts. |
|
|
| The recipes support local reconstruction, whose exact records may depend on the |
| available upstream versions. They are not additional `load_dataset` |
| configurations and do not change the five released test splits. |
|
|
| See [CODE_PROVENANCE.md](CODE_PROVENANCE.md) and |
| [provenance.json](provenance.json) for script origins and retained notices. |
