# World Embedding Regression
World Embedding Regression is the physical-property regression dataset from the
[World Embedding Benchmark](https://arxiv.org/pdf/2610.03632). It contains
5,000 simulation videos across 10 physics families, with 500 examples in each
dataset configuration.
## Usage
```python
from datasets import load_dataset
dataset = load_dataset(
"World-Representation-Lab/World-Embedding-Regression",
"pendulum",
split="test",
)
```
## Fields
- `family`: physics family.
- `id`: unique example identifier.
- `video`: simulation video.
- `regression_attribute`: physical quantity to predict.
- `regression_value`: continuous target value.
The fixed test and scaling splits used by the benchmark are distributed with
the [evaluation code](https://github.com/World-Representation-Lab/World-Embedding-Benchmark).
