Machine Learning for Large-Scale Genomics: Algorithms, Models and ApplicationsIdentifying disease genes from a vast amount of genetic data is one of the most challenging tasks in the post-genomic era. Also, complex diseases present highly heterogeneous genotype, which difficult biological marker identification. Machine learning methods are widely used to identify these markers, but their performance is highly dependent upon the size and quality of available data. In this study, we demonstrated that machine learning classifiers trained on gene functional similarities, using Gene Ontology GO , can improve the identification of genes involved in complex diseases. For this purpose, we developed a supervised machine learning methodology to predict complex disease genes. A quantitative measure of gene functional similarities was obtained by employing different semantic similarity measures. To infer the hidden functional similarities between ASD genes, various types of machine learning classifiers were built on quantitative semantic similarity matrices of ASD and non-ASD genes.

Machine learning has demonstrated potential in analyzing large, complex biological data. In practice, however, biological information is required in addition to machine learning for successful application. In the not so distant past, data generation was the bottleneck, now it is data mining, or extracting useful biological insights from large, complicated datasets. In the past decade, technological advances in data generation have advanced studies of complex biological phenomena. In particular, next generation sequencing NGS technologies have allowed researchers to screen changes at varying biological scales, such as genome-wide genetic variation, gene expression and small RNA abundance, epigenetic modifications, protein binding motifs, and chromosome conformation in a high-throughput and cost-efficient manner Fig. The explosion of data, especially omics data Fig.

Scientific Reports Group Nature. BioData Mining ? To determine the relationship between mutations and cancers, we designed a genojics learning method that we call genomic deep learning GDL. By taking advantages of both gapped k-mer methods and deep learning, gkm-DNN achieved overall better performance compared with gkm-SVM.
