microCLIP: Unsupervised CLIP Adaptation via Coarse-Fine Token Fusion for Fine-Grained Image Classification (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing UA methods for fine-grained image classification rely on coarse-grain visual tokens, which misses fine spatial details. |
| Approach: | They propose a label-free self-training framework that adapts visual features and LLMderived text prototypes using fine-grained cues. |
| Outcome: | The proposed framework improves alignment between finegrained visual regions and rich textual descriptions while updating only layer norms and a tiny head. |
