Study finds feature dimensionality more critical than model complexity for breast cancer classification

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

A new study published on arXiv evaluates machine learning models for classifying breast cancer subtypes using gene expression data from TCGA-BRCA. The research found that feature dimensionality significantly impacts classification performance, often outweighing model complexity. Logistic regression demonstrated the most balanced performance across subtypes, including rare classes, while random forest and SVM showed varying sensitivities to feature selection and dimensionality.
