中文摘要

学习使能的信息物理系统(CPS),包括自动驾驶车辆和无人机,正越来越多地集成基础模型,但碎片化的保障实践无法支撑系统级保证。恢复跨越随机神经、符号与物理边界的工程控制,需要从以模型为中心的评估转向系统级保障。为此提出基础模型保障栈(Foundation Model Assurance Stack),连接三个方向:(i) 神经符号架构,通过显式符号世界模型、推理层与接口约束基础模型;(ii) 语义接地的、基于一致性的测试,将形式规约与符号世界模型同基础模型辅助的规约挖掘、场景生成和测试合成相结合;(iii) 组合式验证与运行时保障,通过模块化契约、等价性检查、经验证的合成、不确定性感知推理以及运行时监控与执行,面向形式化可处理的组件与接口。符号抽象在随机学习与形式推理之间建立保障边界,贯通系统生命周期内的测试、验证与运行时证据。基础模型作为受约束的助手,其输出在正确性可被形式化规定的任何地方都受到独立检查。还识别了规约工程、抽象保真度、证据组合与生命周期认证方面的研究挑战,并勾勒了通向可信、可部署且可认证的学习使能CPS的分阶段议程。

关键要点

  1. 01指出现有学习使能CPS的保障实践碎片化,难以支撑系统级保证,需从模型中心评估转向系统级保障。
  2. 02提出基础模型保障栈,整合神经符号架构、语义接地一致性测试、组合验证与运行时保障三个方向。
  3. 03用符号抽象在随机学习与形式推理间建立保障边界,基础模型输出在可形式化处被独立检查。
  4. 04识别规约工程、抽象保真度、证据组合与生命周期认证四类研究挑战,并给出分阶段议程。

原始英文摘要

arXiv:2610.39547v1 Announce Type: new Abstract: Learning-enabled cyber-physical systems (CPS), including autonomous vehicles and UAVs, increasingly incorporate foundation models, yet fragmented assurance practices provide insufficient support for system-level guarantees. We argue that restoring engineering control across stochastic neural, symbolic, and physical boundaries requires a shift from model-centric evaluation to system-level assurance. We introduce the Foundation Model Assurance Stack, connecting three directions: (i) neuro-symbolic architectures that constrain foundation models through explicit symbolic world models, reasoning layers, and interfaces; (ii) semantically grounded, conformance-based testing that combines formal specifications and symbolic world models with foundation-model-assisted specification mining, scenario generation, and test synthesis; and (iii) compositional verification and runtime assurance that target formally tractable components and interfaces through modular contracts, equivalence checking, verified synthesis, uncertainty-aware reasoning, and runtime monitoring and enforcement. Symbolic abstractions establish assurance boundaries between stochastic learning and formal reasoning, connecting testing, verification, and runtime evidence across the system lifecycle. Foundation models serve as constrained assistants whose outputs are independently checked wherever correctness can be formally specified. We identify research challenges in specification engineering, abstraction fidelity, evidence composition, and lifecycle certification, and outline a staged agenda toward trustworthy, deployable, and certifiable learning-enabled CPS.
