As deep learning(DL) advances, effective feature extraction from big data remains critical for enhancing DL model's performance. This paper proposes a method for feature extraction in the frequency domain, utilizing advantages such as concentrated signal energy and pronounced data features. However, existing frequency component selection algorithms face challenges like difficulty adapting to diverse tasks and achieving only locally optimal results with extended processing times. To address these challenges, we introduce the Adaptive Fast Frequency Selection (AFFS) algorithm, tailored for various subsequent tasks. AFFS incorporates a frequency component selection factor layer, integrating it with the subsequent DL model to select globally optimal frequency component combinations for the DL model. Additionally, we propose a fast selection algorithm to expedite the process, leveraging the experimental observation of rapid convergence of selection factor ranking. Experimental results demonstrate that AFFS achieves superior performance across three datasets and three DL models. By using AFFS to select appropriate frequency components, even though our input data size is only 10\% of the original frequency feature, the classification accuracy of the model is improved by about 1\%. Furthermore, the early stopping mechanism can shorten the selection process by approximately 80\%.
