尽管人工智能在多个领域取得了进展,但现有的AI工具在嵌入物理系统时仍面临挑战,尤其是在不确定性下的长期规划和对未见场景的泛化能力不足。为了解决这一问题,本文提出了一种基于网络的全息数字双胞胎(HDT-Nets)框架,通过主动推理的全息代理来实现实时物理AI推理。每个HDT作为一个层次结构,能够在本地自主推理并与邻近的HDT合作,形成集体智能单元。该框架利用因果马尔可夫毯、主动推理和类别理论等方法,确保在异构代理之间传递的信念保持语义结构,并量化集体智能的优势。

📄 摘要(原文)
Despite advances in artificial intelligence (AI) across multiple sectors, today's AI tools, including deep learning and generative AI, still fail when embedded into physical systems, such as robots and vehicles operating under real-world physical laws. This stems from their inability to maintain reliable world models for long-horizon planning under uncertainty and generalize to unseen scenarios. In this context, wireless networks, through pervasive sensing and communication, can orchestrate physical intelligence. However, current architectures optimize throughput, latency, and reliability and cannot support real-time physical AI coordination, requiring agents to maintain shared spatiotemporal context. To address these challenges, a network of holonic digital twins (HDT-Nets) framework is proposed to deliver real-time physical AI inference through holonic agents that actively reason about their environment rather than passively mirror physical assets. Each HDT is realized as a hierarchical structure spanning the physical agent and network edge, reasoning autonomously at the local level while cooperating with neighboring HDTs to form collectively intelligent units. In HDT-Net, causal Markov blankets spanning sensing, communication, and control determine which agents must coordinate and enable counterfactual reasoning over multi-domain interventions. Active inference within these boundaries unifies perception, action, and learning by minimizing expected free energy while deciding which beliefs to transmit based on their cognitive value to the receiver. Category theory ensures that transmitted beliefs preserve semantic structure across heterogeneous agents with incompatible representations. Finally, integrated information theory quantifies when collective intelligence exceeds independent operation and how network intelligence evolves through coordinated learning and information exchange.
