New visualization framework tackles interpretability gap in categorical machine learning
Researchers introduce cGAP, a visualization framework that addresses a persistent gap in machine learning tooling: interpretable exploration of high-dimensional categorical data. Unlike existing methods that either collapse to low-dimensional projections or sacrifice readability for predictive power, cGAP preserves the original data matrix while embedding subjects and category levels in three-dimensional space mapped to RGB coordinates. The work targets domains where categorical structure dominates (genetics, biomedicine, social science) and reflects growing recognition that interpretability infrastructure lags behind model capability, particularly for non-continuous modalities that remain common in real-world applications.
