FlagGAM: Rule-Based Generalized Additive Modeling for Explainable Tabular Prediction

arXiv:2605.31189v1 Announce Type: new Abstract: Tabular prediction in high-stakes domains requires models that are accurate, transparent, and robust to imperfect inputs. We propose FlagGAM, a rule-defined basis framework that separates feature-level rule construction from prediction. A Flag Core Module converts numerical and categorical variables into sparse, human-readable univariate bases, including threshold flags, category-level flags, tail-deviation bases, and categorical step functions; a default additive head then combines these bases as a restricted GAM-style predictor. Rather than red

Why this matters
Why now

The increasing demand for transparent and trustworthy AI systems in high-stakes domains, coupled with advancements in interpretable machine learning, drives the development of models like FlagGAM.

Why it’s important

Sophisticated readers should care about FlagGAM because it addresses a critical challenge in AI: making complex models explainable and robust for sensitive applications without sacrificing accuracy.

What changes

This research introduces a novel framework that separates feature rule construction from prediction, allowing for more human-readable and auditable AI models, particularly in tabular data scenarios.
