ReCalMatch introduces a reliability‑calibrated semantic framework for semi‑supervised fine‑grained visual recognition, addressing the problem of overconfident pseudo‑label errors that arise when visually similar categories produce incorrect high‑confidence predictions. The method constructs class‑conditioned semantic prototypes from class names and domain‑specific aspects, and computes a visual‑semantic agreement score to calibrate pseudo‑label reliability alongside prediction confidence and entropy. Experiments on datasets such as CUB‑200‑2011, Stanford Dogs, NABirds, and iNaturalist18 demonstrate that ReCalMatch consistently improves strong SSL baselines, especially in low‑label regimes where pseudo‑label noise is most severe.

arXiv:2601. 11670v3 Announce Type: replace-cross Abstract: Pseudo-label selection in semi-supervised learning is commonly driven by maximum-confidence thresholds, yet confidence alone can be unreliable under model overconfidence and class imbalance.
