Technical Principles of AgentGen
Environment Generation
AgentGen uses large language models (LLMs) to generate environmental specifications, including the definition of state space, action space, and transition functions. These specifications are then realized through code generation techniques.
Heuristic Rules and Corpus
During environment generation, AgentGen employs heuristic rules and a diverse corpus to guide LLMs in creating varied environments.
Task Generation
Based on the generated environments, AgentGen further uses LLMs to create corresponding planning tasks, ensuring that tasks are well-matched to their environments.
BI-EVOL Method
AgentGen adopts the BI-EVOL method to adjust task difficulty, which includes easy-evol (simplifying tasks) and hard-evol (complexifying tasks), forming a difficulty-increasing task set.
Zero-Shot Learning
In the initial phase of task generation, AgentGen prompts LLMs to generate a set of initial planning tasks through zero-shot learning.
Instruction Tuning
AgentGen uses instruction tuning with synthetic trajectory data (action-observation pair sequences) to fine-tune LLMs, enhancing their planning capabilities.
Performance Evaluation
AgentGen assesses the performance of models on planning tasks using metrics such as success rate and progress rate, ensuring the effectiveness of training.
Application Scenarios of AgentGen
Robot Control
In the fields of automation and intelligent manufacturing, AgentGen can be used to enhance the autonomous planning and decision-making abilities of robots, enabling them to execute complex tasks more effectively.
Smart Home Systems
AgentGen can be integrated into smart home systems to help them automatically adjust device settings based on user behavior and preferences, improving living comfort and energy efficiency.
Personal Assistants
As personal assistants, AgentGen can assist users with scheduling, task planning, and reminders, enhancing productivity in both personal and professional settings.
Traffic Planning
AgentGen can be utilized for optimizing traffic systems, helping to plan more efficient driving routes, reduce congestion, and improve travel efficiency.
