AMOR: A Recipe for Building Adaptable Modular Knowledge Agents Through Process Feedback
CoRR(2024)
摘要
The notable success of large language models (LLMs) has sparked an upsurge in
building language agents to complete various complex tasks. We present AMOR, an
agent framework based on open-source LLMs, which reasons with external
knowledge bases and adapts to specific domains through human supervision to the
reasoning process. AMOR builds reasoning logic over a finite state machine
(FSM) that solves problems through autonomous executions and transitions over
disentangled modules. This allows humans to provide direct feedback to the
individual modules, and thus naturally forms process supervision. Based on this
reasoning and feedback framework, we develop AMOR through two-stage
fine-tuning: warm-up and adaptation. The former fine-tunes the LLM with
examples automatically constructed from various public datasets and enables
AMOR to generalize across different knowledge environments, while the latter
tailors AMOR to specific domains using process feedback. Extensive experiments
across multiple domains demonstrate the advantage of AMOR to strong baselines,
thanks to its FSM-based reasoning and process feedback mechanism.
