TS-Skill (Free-Form) - SK2 Temporal Localization: leaderboard
TS-Skill questions (Han et al., UCLA and Carnegie Mellon University, 2026) about synthetic, timestamped time series that need only temporal localization: finding the timestamp, interval or event (possibly on another channel) where the answer lies. Free-form protocol: 539 prose answers parsed by GPT-5.4 into the gold answer's structure and scored with type-matched comparators plus a GPT-5.4 rationale judge; mean per-question score on a 0-1 scale, higher is better.
