The Over-Certainty Phenomenon in Modern UDA Algorithms
<|reference_start|>The Over-Certainty Phenomenon in Modern UDA Algorithms: When neural networks are confronted with unfamiliar data that deviate from their training set, this signifies a domain shift. While these networks output predictions on their inputs, they typically fail to account for their level of familiarity with these novel observations. While prevailing works navigate unsupervised domain adaptation with the goal of curtailing model entropy, they unintentionally birth models that grapple with sub-optimal calibration - a dilemma we term the over-certainty phenomenon. In this paper, we uncover a concerning trend in unsupervised domain adaptation and propose a solution that not only maintains accuracy but also addresses calibration.<|reference_end|>
