# ForgeLoc-R1 checkpoints

Qwen2.5-VL-7B-Instruct fine-tuned with GRPO to localize the manipulated segments of a video.
Every folder holds a full checkpoint in Hugging Face format.

| `ablations/af_noprune` | without advantage pruning | ActivityForensics | 62.05 |
| `ablations/af_noos` | without count balancing (m=1) | ActivityForensics | 59.53 |
| `ablations/af_notransform` | without the asymmetric advantage transform | ActivityForensics | 62.90 |
| `ablations/af_bestoverlap` | set term replaced by the best-overlap soft F1 | ActivityForensics | 65.35 |
| `ablations/af_g16` | G'=16 | ActivityForensics | 63.53 |
| `ablations/af_eps0.01` | Sinkhorn coefficient 0.01 | ActivityForensics | 63.49 |
