Research supports the potential use of microbiome as a predictor some diseases. Motivated by findings that data is complex in nature, and there an inherent correlation due to hierarchical taxonomy microbial Operational Taxonomic Units (OTUs), we propose novel machine learning method incorporating stratified approach group OTUs into phylum clusters. Convolutional Neural Networks (CNNs) were used train within each clusters individually. Further, through ensemble approach, features obtained...

Abstract Motivation Research is improving our understanding of how the microbiome interacts with human body and its impact on health. Existing machine learning methods have shown great potential in discriminating healthy from diseased states. However, Machine Learning based prediction using data has challenges such as, small sample size, imbalance between cases controls high cost collecting large number samples. To address these challenges, we propose a deep framework phylaGAN to augment...
