Exploring Cross-Domain Few-Shot Classification via Frequency-Aware Prompting

1 code implementation24 Jun 2024 Tiange Zhang, Qing Cai, Feng Gao, Lin Qi, Junyu Dong

However, most existing methods pay more attention to learning domain-adaptive inductive bias (meta-knowledge) through feature-wise manipulation or task diversity improvement while neglecting the phenomenon that deep networks tend to rely more on high-frequency cues to make the classification decision, which thus degenerates the robustness of learned inductive bias since high-frequency information is vulnerable and easy to be disturbed by noisy information.
