@@ -29,8 +29,8 @@ improving the zero-shot generalization capacity of VLMs.
 According to the characteristics of these VL tasks, we build different fully TTA pipelines with RLCF to improve the zero-shot generalization ability of various VLMs.
 Extensive experiments along with promising
 empirical results demonstrate the effectiveness of RLCF.
