Researchers from Zhejiang University and Swansea University have developed an Adaptive Asymmetric Adapter (A3B2) to improve the fine-tuning of Vision-Language Models (VLMs). Their findings indicate that aggressive fine-tuning of the image encoder can degrade generalization capabilities, especially on out-of-distribution data. The A3B2 system introduces a mechanism that automatically 'brakes' the image encoder's updates when the model's confidence is low, preserving the pre-trained model's robustness while allowing for efficient adaptation.
