World Embedding Regression

World Embedding Regression is the physical-property regression dataset from the World Embedding Benchmark. It contains 5,000 simulation videos across 10 physics families, with 500 examples in each dataset configuration.

Usage

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.
