What Drives Test-Time Adaptation for CLIP? A Controlled Empirical Study from an Update Perspective
arXiv:2606.14299v1 Announce Type: cross Abstract: Vision-Language Models (VLMs) such as CLIP have become a standard backbone for open-vocabulary recognition, yet their zero-shot predictions remain vulnerable to distribution shifts encountered at deployment. Test-Time Adaptation (TTA) has recently been extended to CLIP as a lightweight solution, leading to a rapidly growing body of TTA4CLIP methods. However, empirical progress in this area has largely outpaced our understanding of what truly drives adaptation, where their gains originate, and under which shifts they remain reliable. In this pap
The rapid expansion and deployment of Vision-Language Models like CLIP in real-world applications highlights the immediate need to address their vulnerability to distribution shifts and improve their reliability at inference time.
Improving the robustness and adaptability of foundation models like CLIP is crucial for their reliable integration into diverse AI systems, directly impacting the performance and trustworthiness of downstream applications.
This research provides a more grounded understanding of what makes Test-Time Adaptation effective for VLMs, enabling more targeted and efficient development of adaptable AI models.
