摘要:

现代AI服务计算需求正逐渐从集中式云转向覆盖边缘和终端设备的计算连续体。然而,这些环境的规模、异构性和跨层依赖性使可靠性维护困难。现有故障管理方法通常过于静态、碎片化或复杂,难以支持及时自愈,尤其是在日志噪声和边缘资源限制下。为此,本文提出NeSy-Edge,一种神经符号框架,用于计算连续体中的可信自愈。该框架采用边缘优先设计,边缘节点在资源受限条件下执行本地感知和推理,而云模型仅在最终诊断阶段调用。具体而言,NeSy-Edge将原始运行时日志转换为结构化事件表示,构建先验约束的稀疏符号因果图,并将因果证据与历史故障排除知识结合,用于根本原因分析和恢复建议。我们在代表性Loghub数据集上评估了我们的工作,在多个语义噪声级别下考虑解析质量、因果推理、端到端诊断和边缘侧资源使用。结果表明,NeSy-Edge在最高噪声级别下仍保持稳健,达到75%的根本原因分析准确率和65%的端到端准确率,同时在约1500 MB的本地内存内运行。

英文摘要:

The computational demands of modern AI services are increasingly shifting execution beyond centralized clouds toward a computing continuum spanning edge and end devices. However, the scale, heterogeneity, and cross-layer dependencies of these environments make resilience difficult to maintain. Existing fault-management methods are often too static, fragmented, or heavy to support timely self-healing, especially under noisy logs and edge resource constraints. To address these limitations, this paper presents NeSy-Edge, a neuro-symbolic framework for trustworthy self-healing in the computing continuum. The framework follows an edge-first design, where a resource-constrained edge node performs local perception and reasoning, while a cloud model is invoked only at the final diagnosis stage. Specifically, NeSy-Edge converts raw runtime logs into structured event representations, builds a prior-constrained sparse symbolic causal graph, and integrates causal evidence with historical troubleshooting knowledge for root-cause analysis and recovery recommendation. We evaluate our work on representative Loghub datasets under multiple levels of semantic noise, considering parsing quality, causal reasoning, end-to-end diagnosis, and edge-side resource usage. The results show that NeSy-Edge remains robust even at the highest noise level, achieving up to 75% root-cause analysis accuracy and 65% end-to-end accuracy while operating within about 1500 MB of local memory.
