摘要:SummaryThe gut microbiota plays a crucial role in maintaining health. Monitoring the complex dynamics of its microbial population is, therefore, important. Here, we present a deep convolution network that can characterize the dynamic changes in the gut microbiota using low-resolution images of fecal samples. Further, we demonstrate that the microbial relative abundances, quantified via 16S rRNA amplicon sequencing, can be quantitatively predicted by the neural network. Our approach provides a simple and inexpensive method of gut microbiota analysis.Graphical abstractDisplay OmittedHighlights•A deep convolution network classifies gut microbiota based on fecal sample images•Image-based quantitative prediction of gut microbiota composition is demonstrated•This result provides a simple and inexpensive method of gut microbiota analysisBiochemistry methods; Microbiome
