Domain Adaptation with a Single Vision-Language Embedding
arXiv:2410. 21361v2 Announce Type: replace-cross Abstract: Domain adaptation has been extensively investigated in computer vision but still requires access to target data at the training time, which might be difficult to obtain in real-world autonomous driving scenarios, especially under rare or adverse conditions.

Subspace Alignment for Vision-Language Model Test-time Adaptation
The paper introduces SubTTA, a test-time adaptation method for vision‑language models that aligns the semantic subspaces of visual and textual modalities to improve zero‑shot predictions. It addresses two issues: the modality gap caused by distribution shifts and visual nuisance that masks task‑specific semantics. By minimizing chordal distance between principal subspaces and projecting visual features onto a task‑specific textual subspace, SubTTA refines decision boundaries and achieves an average 2.24% improvement over existing TTA methods.

Domain Recentering and Confidence-Weighted Prior Calibration for Vision-Language Models
The paper introduces Domain Recentering with Confidence Calibration (DRC), a training‑free technique that adapts CLIP to unlabeled target images by fitting a Gaussian mixture and applying posterior‑weighted mean subtraction, followed by a log‑prior correction based on confidence‑weighted predictions. DRC improves cross‑domain accuracy, surpassing zero‑shot CLIP by 4.13 and 5.07 points on ViT‑B/16 and ResNet‑50, and maintains gains under ImageNet distribution shifts.
