The study rigorously compared Lasso regression, Non-negative Matrix Factorization (NMF), Principal Component Analysis (PCA), and Point Biserial Correlation for feature extraction. Lasso consistently demonstrated superior performance in capturing important patterns.
Model effectiveness was evaluated using cross-validation, ROC curves, and PR curves. Given the data imbalance inherent in biomarker studies, PR curve improvement was prioritized as a critical indicator, showing a significant boost of up to 0.15.
Seven key genes were identified: sgrn, itk, ptprc, cst7, hcst, cnot6l, and rgs1. These genes play crucial roles in immune cell activation, regulation, and signaling pathways, significantly impacting the tumor immune microenvironment.

Impact of Optimized LASSO in Patient Data
The optimized LASSO algorithm dramatically improved the ability to identify key genes associated with tumor progression. For example, in Patient 1, the PR curve improved from 0.68 to 0.81, and the ROC curve from 0.74 to 0.87. This enhanced precision allows for more reliable identification of true positive biomarkers, which is critical in oncology. The improved model can discern subtle but significant gene expressions that traditional methods might overlook.
This translates to a 13% increase in diagnostic confidence for Patient 1.
