AURORA-AI动态调整资源分配,提升AI系统在干扰下的性能与公平性。
Adaptive Utility driven Resource Orchestration for Resilient AI (AURORA-AI)

- 基于反馈控制与稳定性理论,动态分配计算资源。
- 黑天鹅事件后22步内恢复,优于静态策略88步。
- 兼顾公平性、效率与鲁棒性,适合高风险部署场景。
现代AI系统常在非平稳的计算、人口和操作条件下运行,静态资源分配策略会降低预测性能及公平性、可解释性等以人为本的属性。本文提出AURORA-AI,一个自适应效用驱动的资源编排框架,融合哈密顿-雅可比-贝尔曼反馈控制、基于李雅普诺夫的稳定性监控与公平性感知的复合效用函数,形成闭环策略。该框架持续在异构AI模型间重新分配计算预算,确保在扰动下全局效用(包含预测性能、人口平等、成本、延迟、鲁棒性与可解释性)最大化。在同时注入人口偏差冲击、渐进概念漂移与突发黑天鹅事件的离散时间仿真中评估,相比静态、轮询、贪婪、LinUCB及近端策略优化(PPO)深度强化学习代理,AURORA-AI在黑天鹅事件后仅22步恢复,远优于静态基线的88步;α分位数与超分位数分别提升29%与25%;平均与最大人口平等差距下降;李雅普诺夫稳定运行步骤比例上升。结果表明,基于稳定性理论的公平性感知自适应编排是实现韧性人本化AI部署的可行且理论支撑充分路径。
原文摘要 · Abstract (English)
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 policy.The 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.
