(a) ACC performance of different k-mer EnhancerBERT models, where the 3mer-model achieves the best performance over all models; (b) values of four metrics for assessing performance of EnhancerBERT versus the different NLP technologies, showing that dynamic semantic information in EnhancerBERT has the best characterization capability; (c) compares degree of correlation of different k-mer dynamic semantic information using Pearson correlation coefficient, 3mer-model has the clearest correlationship between features, which support SMFM in identifying enhancers.
