M6A-GSMS: Computational identification of N-methyladenosine sites with GBDT and stacking learning in multiple species.

N-methyladenosine (mA) is one of the most abundant forms of RNA methylation modifications currently known. It involves a wide range of biological processes, including degradation, stability, alternative splicing, etc. Therefore, the development of convenient and efficient mA prediction technologies are urgent. In this work, a novel predictor based on GBDT and stacking learning is developed to identify mA sites, which is called M6A-GSMS. To achieve accurate prediction, we explore RNA sequence information from four aspects: correlation, structure, physicochemical properties and pseudo ribonucleic acid composition. After using the GBDT algorithm for feature selection, a stacking model is constructed by combining seven basic classifiers. Compared with other state-of-the-art methods, the results show that M6A-GSMS can obtain excellent performance for identifying the mA sites. The prediction accuracy of , , , and reaches 88.4%, 60.8%, 80.5%, 92.4% and 61.8%, respectively. This method provides an effective prediction for the investigation of mA sites.
