Sterzhang/motion-train

MotionLM motion question answering

This dataset combines the corrected MotionLM training and test exports into one repository with 8,202 train examples and 1,000 test examples. Each example contains a multiple-choice question, answer, and 16 chronological JPEG frames. The frames column is a list of Hugging Face Image features, with the original JPEG bytes embedded in self-contained Parquet shards. The Dataset Viewer can display the frames alongside each question and answer.

Usage

from datasets import load_dataset

dataset = load_dataset("Sterzhang/motion-train")
train = dataset["train"]
test = dataset["test"]
example = train[0]
print(example["question"], example["options"], example["answer"])
example["frames"][0]  # a PIL image

For streaming access, use load_dataset("Sterzhang/motion-train", streaming=True).

Fields

• id, question, options, answer, answer_index, answer_letter: the QA; answer indices are zero-based and letters start at A.
• frames: 16 original 1280 × 720 RGB JPEG images, in chronological order.
• frame_indices: source-relative frame indices supplied by the export. Original video frame rate and absolute source time are unavailable.
• category: gripper_width, gripper_rel_to_obj, obj_rel_to_camera, obj_rel_to_obj, or trajectory_shape.
• split, source_id, image_paths, label_revision: split and export provenance.
• generated_source_index, source_index: source indices supplied by the original train/test exports. Unused fields are null.
• reported_answer, reported_answer_letter: retained publisher correction provenance for the three test records that originally included these fields; otherwise null.
