Book Relationship Map (Knowledge Graph View)#
Reading guide. This note is an English, knowledge-graph–oriented companion to the Chinese edition’s relationship map. It uses Obsidian-style
[[double brackets]]for conceptual anchors (standalone readable; links need not resolve to separate notes) and Mermaid diagrams to show how the book’s 25 chapters and core ideas connect.

Concept links:
[[Symbolic AI]] and [[Connectionism]] are the two major paradigms; their complementary strengths define the [[Dual-peak dilemma]].
[[System 1 and System 2]] cognitive theory analogizes fast vs. slow thinking with connectionism vs. symbolic AI.
[[Neuro-symbolic AI]] is the central path beyond the dual-peak dilemma and runs through the book.
The [[Kautz neuro-symbolic spectrum]] classifies integration as [[Symbolic-dominant]], [[Hybrid-pipeline]], and [[Deeply-fused]] engineering layers.
[[Certification readiness]] evaluates design choices along explainability, latency, scalability, and certification dimensions.

[[Logic Tensor Networks]] and [[Semantic Loss]] exemplify logic-as-loss.
The [[Hybrid reasoning architecture]] splits into a symbolic channel ([[Deterministic evidence extraction]]) and a neural channel ([[Semantic completion]]), fused by arbitration into [[Grounded answering]].
[[GraphRAG]] retrieves entity–relation subgraphs from [[SkyKG]], replacing flat document retrieval to improve faithfulness.
[[Probabilistic logic programming]] ([[DeepProbLog]], [[NeurASP]]) and [[Differentiable theorem proving]] enable end-to-end neuro-symbolic fusion.

[[Conformal prediction]] uses [[Nonconformity score]]s to produce [[Prediction sets]] / [[Prediction intervals]] with [[Marginal coverage guarantee]].
[[Composite conformal score]] unifies neural error and symbolic violation penalties: \(s = s_{\text{neural}} + \lambda P_{\text{symbolic}}\)
[[Online monitoring]] combines [[Martingale monitoring]], [[Concept drift]] detection, and [[Anomaly / OOD detection]] for runtime assurance.
[[SkyCert]] wraps inference into [[Certification-grade outputs]].
[[Multi-level explanations]] span local perception, symbolic rules, and causal counterfactuals.

Concept links:
The [[Computing gap]] reflects combinatorial explosion in symbolic reasoning, [[Neighborhood explosion]] in GNNs, and autoregressive latency in LLMs.
[[Tiered deployment]] (device–edge–cloud) bridges the gap, together with [[Model compression]] / [[Knowledge distillation]].
Under [[Cloud–edge collaboration]], [[Event-driven scheduling]] avoids global polling; [[Eventual consistency]] supports distributed sync.
The [[Real-time response loop]] links risk detection, actuation, and logging.
[[Spatiotemporal-aware graph partitioning]] uses [[Boundary buffers]] to reduce cross-partition seams; [[Hybrid parallel pipeline]] supports high concurrency.
[[SkyGrid]] orchestrates reasoning, governance, and elasticity at city scale.
[[Platform implementation]] uses [[Three-flow unification]] (data, control, evidence) and [[Modular design]] to build a [[Governance closed loop]].
[[Hard real-time constraints]] are non-negotiable in safety-critical systems.
