![]() Specifically, the LSS model assumes that the regression function is a linear combination of piecewise constant Boolean interaction terms. Inspired by the thresholding behavior in many biological processes, we first introduce a discontinuous nonlinear regression model, called the “Locally Spiky Sparse” (LSS) model. However, theoretical studies into how tree-based methods discover Boolean feature interactions are missing. They have shown great promise for Boolean biological interaction discovery that is central to advancing functional genomics and precision medicine. Iterative RFs (iRFs) use a tree ensemble from iteratively modified RFs to obtain predictive and stable nonlinear or Boolean interactions of features. Random Forests (RFs) are at the cutting edge of supervised machine learning in terms of prediction performance, especially in genomics. ![]()
