Gradient Boosting for Enterprise Decision Prediction: XGBoost and LightGBM as the Decision Layer of Agentic Companies
Why enterprise data is often tabular and how gradient boosting ensembles support approval prediction, risk scoring, and outcome estimation
While deep learning dominates many unstructured tasks, enterprise decision data is frequently tabular: structured features describing decisions, agents, contexts, and outcomes. This paper formalizes gradient boosting (XGBoost/LightGBM) as the Decision Layer (Layer 2) of the agentic company stack, details feature-engineering patterns for enterprise decision tables, and introduces SHAP-based explainability workflows for governance audits. Across evaluated datasets, the approach achieved 91.3% approval-prediction accuracy, 0.94 AUC on risk scoring, and full SHAP traceability integrated with MARIA OS responsibility gates.
Fail-Closed Gate Design for Agent Governance: Responsibility Decomposition and Optimal Human Escalation
Responsibility decomposition-point control for enterprise AI agents
When an AI agent modifies production code, calls external APIs, or alters contracts, responsibility boundaries must remain explicit. This paper formalizes fail-closed gates as a core architectural primitive for responsibility decomposition in multi-agent systems. We derive gate configurations via constrained optimization and use internal simulations to illustrate how a 30/70 human-agent ratio can preserve responsibility coverage while reducing decision latency versus full human review.
MAX vs Average Scoring: A Mathematical Analysis of Fail-Closed Gate Design
Why average-score gates structurally fail and how MAX-based scoring achieves zero false-acceptance under defined conditions
Average-score gating can dilute critical risk signals by construction. For example, a low score in one domain may mask a high score in another under arithmetic averaging. This paper analyzes why MAX-based scoring removes that masking effect in fail-closed designs, and reports zero false acceptance under the stated conditions in evaluated datasets.
