Fig. 3From: Biomarker interaction selection and disease detection based on multivariate gain ratioIllustration of BDA. In this example, we randomly select five biomarkers \(\left\{ x_{b_1},x_{b_2},x_{b_3},x_{b_4},x_{b_5}\right\}\) as the initial subset. For ease of display, the biomarkers \(\left\{ x_{b_1},x_{b_2},x_{b_3},x_{b_4},x_{b_5}\right\}\) is represented by the subscript interaction \(\left\{ 1,2,3,4,5\right\}\)Back to article page
