a Machine learning were trained by 712 samples from marine habitats and used to predict the antibiotic resistance threats in global marine habitats. b Accuracy rate of machine learning with different discretization methods. K-means exhibited higher accuracy rate than equal frequency and the best model (accuracy rate = 76.06%) were chosen for the further prediction. c The ROC plots confirmed the high performance of the best model in classification of risk ranks. d Latitude as well as the climate change stressors exhibited the high importance in predicting the antibiotic resistance risk. The full name of each indicator can be found in Supplementary Data 12. e The map of ARG risk in marine habitats with prediction results by machine learning, which was drawn by ArcGIS in 20′ × 20′ resolution.
