# RepresentationLearning dataset
Preprocessed WiFi packets for three wireless tasks, used to train and attack the
multi-task representations in
[RepresentationLearning](https://github.com/nasimsoltani/RepresentationLearning).
Pretrained models and the run registry are in
[`Aadharsh/RepresentationLearning-models`](https://huggingface.co/Aadharsh/RepresentationLearning-models).
The packets are derived from the [ORACLE RF fingerprinting dataset](https://genesys-lab.org/oracle)
(16 USRP X310 transmitters recorded at 11 distances, 2–62 ft).
## Files
| File | Size | Contents |
|---|---|---|
| `OracleDatasetProcessed-arranged.tar.gz` | 3.3 GB | 416,244 `.mat` files (see below) |
| `rf_partition_dict_0.5.pkl` | 5.8 MB | train/val/test split and CFO normalisation constants |
## Layout
```bash
tar xzf OracleDatasetProcessed-arranged.tar.gz
```
The archive has a doubled top-level directory. The `.mat` files are in
`OracleDatasetProcessed-arranged/OracleDatasetProcessed-arranged/`; point
`DATA_BASE_PATH` there.
One sample is a **triplet** sharing the suffix `_run1_Radio<r>_<d>ft_<i>.mat`:
| Prefix | Variables | Task |
|---|---|---|
| `RFfingerprinting` | `Packet` (4000×1 complex), `Radio` (label, `"Radio0"`–`"Radio15"`) | RF fingerprinting (16 classes) |
| `CFOEstimation` | `LSTF` (160×1 complex), `CFO` (scalar, Hz) | CFO estimation |
| `ChannelEstimation` | `LLTF` (160×1 complex), `EstChannnel` (52×1 complex) | Channel estimation |
`EstChannnel` really is spelled with three n's. The archive also contains 24,525
`CFOEstimation` files without RF/channel partners; no split references them.
## Split
`rf_partition_dict_0.5.pkl` is a dict:
| Key | Value |
|---|---|
| `train` / `val` / `test` | lists of `RFfingerprinting_*.mat` filenames: 91,323 / 13,070 / 26,180 |
| `mean_cfo`, `std_cfo`, `max_cfo` | CFO statistics of the training split, used to normalise CFO targets |
Filenames are relative to `DATA_BASE_PATH`. The registry's test metrics for runs
from July 2025 onward were computed on this split, so use it unchanged when
comparing with the registry.
## Loading
```bash
git clone https://github.com/nasimsoltani/RepresentationLearning.git
cd RepresentationLearning && cp .env.example .env # set DATA_BASE_PATH and PKL_FILE_PATH
python code/rep_lr/inference.py # evaluate the best released model
```
Each input is normalised to unit RMS and split into I/Q channels by
`code/rep_lr/py_datasets.py`.
