A Hierarchical Error-Corrective Graph Framework for Autonomous Agents with LLM-Based Action Generation
This paper introduces the Hierarchical Error-Corrective Graph (HECG) framework for robust autonomous agents using LLM-based action generation. HECG integrates three innovations: Multi-Dimensional Transferable Strategy (MDTS) for precise strategy selection, Error Matrix Classification (EMC) for structured error attribution, and Causal-Context Graph Retrieval (CCGR) for deep contextual understanding. Experiments in simulated environments (e.g., VirtualHome) demonstrate that HECG significantly outperforms state-of-the-art LLM planners, achieving substantial improvements in task success rates, execution efficiency, and error recovery, bridging high-level semantic reasoning with robust low-level execution.

Reduction in Negative Transfer Risk with MDTS
| Feature | EMC | Traditional Feedback |
|---|---|---|
| Error Categorization | 10 types (severity/recoverability) | Success/Failure Binary |
| Attribution | Structured (cause, type, source) | Aggregated, unclear |
| Guidance for Correction | Clear, actionable, multi-level | Post-hoc replanning |
| Dynamic Adaptability | High (graph traversal) | Low (fixed sequence) |
CCGR: Contextual Graph Retrieval in VirtualHome
Problem: Traditional RAG uses superficial semantic similarity, leading to suboptimal policy adaptation and inconsistent planning, especially in dynamic, partially observable environments. It overlooks structural, causal, and temporal dependencies.
Solution: CCGR constructs graphs from historical states, actions, and event sequences to identify subgraphs most relevant to the current context. This captures deep structural dependencies beyond flat vector similarity, enabling agents to accelerate strategy adaptation.
Result: Significantly improved retrieval quality and semantic alignment, leading to more reliable experience reuse and enhanced execution robustness in complex embodied environments.
