Abstract
Genetic, proteomic, and other biologically derived data sets are often ill-conditioned with many more variables than data records. Furthermore, the variables are often highly correlated as well as coupled. These attributes make such data sets very difficult to analyze with conventional statistical and machine learning techniques. The ParetoGP approach implemented within DataModeler exploring the trade-off between model complexity and accuracy enables attacking such data sets with dual benefits of identifying key variables, associations, and metavariables along with providing concise, explainable, and human-interpretable predictive models. Transparency of key variables, model structures, and response behaviors provide a substantial benefit relative to conventional machine learning and the associated black-box models. In this chapter, we describe the analysis methodology and highlight benefits using available biological data sets.
