TreeAgent: A Generalizable Multi-Agent Framework for Automated Bias Labeling in Forestry via Compiled Expert Rules and Vision-Language Models
Summary
TreeAgent, a novel multi-agent system (MAS), automates bias labeling in forestry, specifically for tree height bias classification in remote sensing, addressing the inherent variability, slowness, and inconsistency of human expert annotations. This framework orchestrates expert decision trees, which serve as structural priors, with Vision-Language Models (VLMs) that perform localized semantic perception at individual nodes. Multi-agent voting is employed to mitigate VLM stochasticity. The system formalizes a Decoupled Declarative Decision (D3) Framework, enabling zero-modification generalization across diverse expert-defined decision structures. TreeAgent outperforms supervised machine learning baselines on a tree bias classification testbed and significantly reduces the required expert labeling effort, demonstrating its ability to reproduce expert-defined labeling procedures at substantially lower annotation costs while maintaining interpretability.
Key takeaway
For Machine Learning Engineers developing annotation pipelines in expert-driven domains like forestry, TreeAgent offers a compelling alternative to purely human or supervised ML approaches. You should consider integrating expert decision trees with Vision-Language Models and multi-agent voting to achieve automated, interpretable, and cost-effective labeling. This approach significantly reduces expert labeling effort and generalizes across diverse decision structures, accelerating data preparation for specialized ML tasks.
