๐Ÿง  Reflection Agent: Intelligent Reflection Mechanism in Dynamic Environments

Python License GitHub stars GitHub forks GitHub issues GitHub pull requests Research Demo

๐Ÿ“– Project Introduction

This project implements a reflective agent (Reflection Agent) that can autonomously learn, adapt, and optimize strategies in dynamically changing maze environments. By introducing reflection mechanisms, the agent significantly improves performance in complex environments.

๐ŸŽฏ Core Features

๐Ÿ”„ Reflection Mechanism

  • Real-time Performance Evaluation: Self-reflection every 5 steps
  • Dynamic Strategy Adjustment: Automatically adjust exploration rate and learning rate based on performance
  • Environment Change Detection: Intelligently identify environment changes and adapt quickly

๐Ÿง  Dual Memory System

  • Short-term Memory: Quickly adapt to environment changes
  • Long-term Memory: Preserve stable general strategies
  • Intelligent Balance: Dynamically adjust memory weights based on environment stability

๐ŸŽฎ Intelligent Decision Making

  • Direction Priority: Prioritize directions toward the goal
  • Wall Memory: Remember and avoid known walls
  • UCB Algorithm: Optimal decision making balancing exploration and exploitation

๐Ÿ“Š Experimental Results

In a 100-episode dynamic maze experiment:

Metric Baseline Agent Reflection Agent Improvement
Success Rate 2.0% 40.0% +38.0%
Average Reward -97.17 30.52 +131.4%
Total Successes 2 times 40 times 20x

๐Ÿ”ฌ Technical Details

Reflection Mechanism Parameters

  • Reflection Frequency: Every 5 steps
  • Confidence Threshold: 0.25
  • Adaptation Threshold: 0.45
  • Environment Stability Threshold: 0.6

Learning Parameters

  • Learning Rate: 0.5 (dynamic adjustment)
  • Discount Factor: 0.9
  • Exploration Rate: 0.9 โ†’ 0.3 (dynamic decay)

๐Ÿ“ˆ Performance Analysis

Environment Change Detection

The agent can detect real-time changes in maze structure, including:

  • Wall position changes
  • Reward function changes
  • Goal position changes

Strategy Adaptation

When environment changes are detected, the agent will:

  1. Increase exploration rate
  2. Clear partial outdated memories
  3. Adjust learning parameters
  4. Reflect more frequently

๐ŸŽจ Visualization

The project includes a complete visualization interface showing:

  • Maze layout
  • Agent movement trajectories
  • Real-time performance metrics
  • Environment change detection
