LAPVQA — Radiology Report Generation (Frozen Off-the-shelf Encoders)
Part of the LAPVQA collection.
Description
Generative decoder heads for Radiology Report Generation (RRG) on MIMIC-CXR, trained on top of five frozen off-the-shelf vision encoders. Each file contains the decoder weights; the encoder is not bundled.
Results (MIMIC-CXR test set)
| Encoder | BLEU-4 | ROUGE-L | RadGraph-s |
|---|---|---|---|
| CLIP ViT-L/14 | 0.034 | 0.168 | 0.197 |
| Florence-2 | 0.035 | 0.169 | 0.205 |
| SigLIP | 0.036 | 0.168 | 0.211 |
| CoCa | 0.030 | 0.160 | 0.193 |
| OWLv2 | 0.034 | 0.169 | 0.197 |
SigLIP achieves the best RadGraph-s (0.211) among all frozen encoders, consistent with its larger patch-token count (729 tokens at 384 px) providing finer spatial detail.
