Researchers have introduced Contrastive Residual Energy Test-time Adaptation (CreTTA), a novel method to improve model robustness and real-world generalizability. Unlike previous approaches that focus on conditional distribution and suffer from poor calibration, CreTTA models the marginal distribution without relying on label predictions. This is achieved by reformulating adaptation as learning a residual energy function with a contrastive objective that eliminates the need for costly sampling. AI
