The pipeline of DNA sequence classification using the proposed PCVR. This pipeline consists of two stages: the MAE pre-training stage for robust features and the fine-tuning stage for taxonomic classification. a The upper part of the pipeline illustrates the MAE self-supervised pre-training, which injects robust recognition abilities for images to the ViT encoder through reconstruction learning and obtains PCVR. b The lower part shows the fine-tuning stage, depicting the hierarchical feature fine-tuning structure upon the learned PCVR
