Figure 6. Machine learning screens biomarkers for diagnosing OA. (A, B) The LASSO regression revealed that the number of genes corresponding to the lowest point of the curve (n = 6) is best suited for the diagnosis of OA. (C, D) Random Forest algorithm showed errors in OA; each gene is ranked according to its importance score. (E) The Venn diagram depicts the intersection genes of LASSO and RF results.
