Abstract

fetched live from OpenAlex

Abstract With the advent of high‐throughput chemogenomic data, it becomes crucially important to extract the important genes which influence the drug activities among the huge number of candidate genes. By employing model selection technique, especially designed for high‐dimensional data, we propose to develop a systematic approach to construct the network elucidating the dependency relationships among the drugs and the genes. Based on the extended Bayesian Information Criterion, we are able to select the best parsimonious network structure. A real National Cancer Institute (NCI)‐60 panel data set is analyzed to demonstrate the utility of the method. The biological implications of the results are discussed.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
