# SOUL

**SOUL** is the data suite for human behavior simulation used in
[Reinforcing Human Behavior Simulation via Verbal Feedback](https://arxiv.org/abs/2605.20506) (DITTO),
spanning conversation, social simulation, social cognition, role-play, and human-centric evaluation.

- 📄 Paper: https://arxiv.org/abs/2605.20506
- 💻 Code: https://github.com/sunnweiwei/OdysSim
- 🤖 Model: https://huggingface.co/sunweiwei/Ditto-8B

## Structure

Files are kept in their original format, bound to our training/eval framework, and are organized
into two folders:

- `train/` — RL training data, one parquet per task.
- `test/` — evaluation data, one parquet per task.

Because each task's `extra_info` schema differs across tasks and between train/eval, each
task+split is exposed as its own config (`<task>_train`, `<task>_test`) so it loads cleanly:

```python
from datasets import load_dataset
train = load_dataset("sunweiwei/Soul", "userllm_train", split="train")
test  = load_dataset("sunweiwei/Soul", "userllm_test",  split="test")
```

You can also read any parquet directly, e.g. `train/userllm_rl_train.parquet` /
`test/userllm_val.parquet`.
