Paper AbstractExpand

Modern AI systems are increasingly deployed under non-stationary computational, demographic, and operational conditions in which static resource allocation strategies degrade both predictive performance and human-centric properties such as fairness and explainability. This paper presents AURORA-AI, an Adaptive Utility-driven Resource Orchestration framework for Resilient AI that unifies Hamilton-Jacobi-Bellman feedback control, Lyapunov-based stability monitoring, and a fairness-aware composite utility into a single closed-loop this http URL framework continuously redistributes computational budget across a population of heterogeneous AI models so that the global utility, defined jointly over predictive performance, demographic parity, cost, latency, robustness, and interpretability, remains maximised under disruption. The framework is evaluated in a stress-rich discrete-time simulation that concurrently injects demographic bias shocks, gradual concept drift, and abrupt black-swan disruptions, and is compared against five established controllers including Static, Round Robin, Greedy, LinUCB, and a deep reinforcement-learning agent based on Proximal Policy Optimisation. AURORA-AI achieves immediate recovery from the black-swan event compared to eighty-eight time steps for the Static baseline and twenty-two for Proximal Policy Optimisation, lifts the alpha-quantile and the super-quantile by twenty-nine and twenty-five percent respectively, simultaneously reduces the mean and maximum demographic parity gap, and increases the fraction of Lyapunov-stable operating steps. These results indicate that fairness-aware adaptive orchestration grounded in stability theory is a practical and theoretically motivated path toward resilient human-centric AI deployment.

Modern AI systems are increasingly used in unpredictable, real-time environments, yet they often rely on static resource allocation strategies that fail when conditions change. When faced with demographic bias, data drift, or sudden "black-swan" disruptions, these systems often suffer from degraded performance, unfairness, and instability. AURORA-AI is a new framework designed to solve this by acting as an intelligent, adaptive "orchestrator" that continuously redistributes computational resources across a group of AI models to ensure the entire system remains stable, fair, and accurate.

How the Framework Works

AURORA-AI functions as a closed-loop control system. Instead of waiting for a system to fail, it uses a combination of advanced mathematical tools to monitor and adjust performance in real-time:

  • Stability Monitoring: It uses Lyapunov-based stability theory to ensure that the system stays within safe operating bounds. If a disturbance occurs, the framework identifies it as a shift in energy and works to dissipate that "perturbation energy" rapidly.

  • Fairness-Aware Utility: The framework evaluates models based on a composite score that includes predictive accuracy, cost, latency, interpretability, and demographic parity. It treats fairness as a core requirement rather than an afterthought.

  • Predictive Orchestration: By using Hamilton-Jacobi-Bellman (HJB) feedback control, the system can anticipate failures. For example, if a specific model begins to show signs of demographic bias, the framework proactively reduces its funding before the issue impacts the global system.

Resilience Under Stress

To test the framework, researchers simulated a "stress-rich" environment featuring three simultaneous challenges: gradual concept drift, demographic bias shocks, and abrupt black-swan disruptions.
Compared to five other methods—including standard static allocation, greedy strategies, and deep reinforcement learning (PPO)—AURORA-AI demonstrated superior resilience. When a black-swan event occurred, AURORA-AI achieved immediate recovery, whereas the static baseline took 88 time steps and the PPO agent took 22 steps to return to normal operation.

Key Performance Gains

The evaluation showed that AURORA-AI significantly improves the reliability of AI deployments. By focusing on stability and tail-risk management, the framework:

  • Lifts Performance Floors: It increased the alpha-quantile and super-quantile metrics by 29% and 25%, respectively, compared to a static baseline. This means the system is much less likely to experience catastrophic performance drops.

  • Reduces Bias: It successfully lowered both the mean and maximum demographic parity gaps, ensuring more equitable outcomes.

  • Maintains Stability: It increased the percentage of time the system operated in a "Lyapunov-stable" state, meaning it spent more time in a controlled, predictable configuration than the baseline models.

Why This Matters

The results suggest that grounding AI resource management in stability theory is a practical path forward for deploying human-centric AI. By treating the AI population as a dynamic system that requires constant, intelligent balancing, AURORA-AI provides a way to maintain high performance and fairness even when the operating environment is volatile or unpredictable.
