R4JEPA benchmark annotations

This repository stores the annotation manifests used for the R4JEPA experiments. It does not redistribute benchmark videos, images, pretrained weights, or processed tensor caches.

The annotations/ directory contains the exact MV-Kubric, Physion V1.5, and CLEVRER manifests used by the experiment pipeline. The tools/ directory records the upstream download URLs and preparation commands. Users must follow the licenses and terms of the upstream datasets.

Expected manifest sizes:

Manifest Records
mvkubric_train.jsonl 450
mvkubric_dev.jsonl 50
mvkubric_test.jsonl 30
physion_readout.jsonl 5,608
physion_test.jsonl 1,035
clevrer_train.jsonl 10,000
clevrer_validation.jsonl 5,000

SHA256SUMS records the uploaded annotation file hashes. Download and preparation code is included for reproducibility; upstream media remains at its original source.
