However, fine-tuning it for small downstream tasks with limited labeled samples is challenging. Efficient transfer learning (ETL) methods adapt VLMs with few parameters, but require careful per-task hyperparameter tuning using large validation sets. To overcome this, the authors propose CLAP, a principled approach that adapts linear probing for few-shot learning. CLAP consistently outperforms ETL methods, providing an efficient and robust approach for few-shot adaptation of large vision-language models in realistic settings where hyperparameter tuning with large validation sets is not feasible. |
