PAL-Bench (PAL-TRACE) - Person Identity Resolution: leaderboard
PAL-Bench (Yan et al., 2026) asks a system to reconstruct a person's profile from a synthetic longitudinal photo album seen only through perception outputs (captions, OCR, entities, face clusters, timestamps and coarse metadata), over 50 users and 2,799 hidden targets. Runs use the authors' PAL-TRACE framework with the listed LLM as backbone and a fixed Qwen3.6-35B-A3B judge; this board is person identity resolution, the harmonic mean of the share of recurring people the profile names and the share of those bound to the right face cluster, from 0 to 1 averaged over users, higher is better.
Metric: Person identity resolution (0-1; harmonic mean of the share of a user's hidden social persons, 653 in all, that the profile names and the share of those bound to the correct face cluster; PAL-TRACE framework with the listed LLM as reconstruction backbone; 50 synthetic users, macro-averaged over users; Qwen3.6-35B-A3B semantic judge).
