In his previous research experience, Jiazheng Miao noticed that the performance of current bioinformatic tools for predicting the gene copy number (GCN) of prokaryotic 16S rRNA is not satisfactory enough. Therefore, he employed deep learning, the state-of-the-art algorithms in Data Science, to develop a new prediction tool. The developed tool, ANNA16, could help microbiologists more accurately determine the composition of the microbiota and also brought a new method for interpreting genetic information.a
