Continual Test-Time Adaptation (CTA) is a challenging task that requires adapting models to changing target domains without prior notice. The key challenge is mitigating biased predictions and overconfident outcomes, which can impact model performance significantly. To address this, the author proposes techniques like class-wise exponential moving average target prototypes and source distribution alignment.
In CTA, models face drastic changes in input distribution during test-time, leading to biased predictions favoring certain classes over others. The proposed method aims to alleviate this bias issue by introducing class-wise exponential moving average target prototypes and aligning target distributions with source distributions.
Experimental results show that the proposed method achieves notable performance improvements in CTA scenarios without adding complexity or requiring access to source domain data at test-time. By addressing biased predictions and improving calibration, the method enhances model adaptability to changing target distributions.
The study highlights the importance of mitigating bias in models for effective Continual Test-Time Adaptation. By introducing innovative techniques like exponential moving average target prototypes and source distribution alignment, the author demonstrates significant performance gains without compromising adaptation time efficiency.
Key points include addressing biased predictions in models during Continual Test-Time Adaptation through innovative techniques like class-wise exponential moving average target prototypes and source distribution alignment. Experimental results showcase notable performance improvements without significant adaptation time overhead.
