   "description": "Substream Recollection is a controlled benchmark for testing whether long-context VLMs / LLMs can recall whether a short probe substream occurred inside a longer parent stream. It pairs synthetic streams (low / medium / uniform entropy, lengths L=8..4096) with EasyHuman rendered 3-belt videos and a natural-video sub-benchmark drawn from EPIC-Kitchens-100 and SoccerNet. The dataset is organized into four top-level configs: text (synthetic substream text-modality questions), synthetic_video (rendered synthetic substream videos), easyhuman (rendered 3-belt EasyHuman videos and their text-modality counterparts), and natural_video (real-world videos).",

(1) Synthetic streams over a fixed alphabet of 16 symbols, generated by a variable-order n-gram process (rule lengths 1-8) and resampled until the realized stream falls within a target empirical Lempel-Ziv entropy band (low ~0.7 bits/symbol, medium ~1.9 bits/symbol, max-entropy = 4.0 bits/symbol = uniform i.i.d.). The 'EasyHuman' diagnostic split is generated separately by hand-specified pattern templates (repeating motifs and counting sequences) with controlled deviations. (2) A natural-video subset of 1,028 clips drawn from EPIC-Kitchens-100 (egocentric cooking videos) and SoccerNet (sports broadcasts) at L in {8, 16, 64, 128, 512, 1024}; EPIC-Kitchens-100 derived clips ship in this repo and SoccerNet rows ship as provenance metadata only.",

EasyHuman labels are derived from the candidate_tag suffix ('_present' / '_absent'). Natural-video labels are derived from EPIC-Kitchens-100 narration metadata and SoccerNet event annotations as released by the upstream projects; no manual relabeling was performed by this work.",
