srini911/tcga-brca-subtype-classifier

This repository is a reproducible research workflow for classifying breast tumors into four PAM50 subtypes from TCGA RNA-seq. Its principal path downloads cohort data, transforms and labels expression features, compares classifiers, and produces evaluation results. Two companion analyses inspect influential genes and subtype confusions, and test smaller gene panels. The graph follows the documented script order; source excerpts confirm the major data reads, model work, and result writes. Raw and processed data directories are generated and gitignored, so they are not shown as repository files.
