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

python maze_visualization.py- Reflection Frequency: Every 5 steps
- Confidence Threshold: 0.25
- Adaptation Threshold: 0.45
- Environment Stability Threshold: 0.6
- Learning Rate: 0.5 (dynamic adjustment)
- Discount Factor: 0.9
- Exploration Rate: 0.9 โ 0.3 (dynamic decay)
- Experience Buffer Size: 1000
The agent can detect real-time changes in maze structure, including:
- Wall position changes
- Reward function changes
- Goal position changes
When environment changes are detected, the agent will:
- Increase exploration rate
- Clear partial outdated memories
- Adjust learning parameters
- Reflect more frequently
The project includes a complete visualization interface showing:
- Maze layout
- Agent movement trajectories
- Real-time performance metrics
- Environment change detection
- Reflection Agent: Dynamic Environment Adaptation through Meta-Learning - Complete research paper with theoretical foundations
- Implementation Details and Experimental Results - Comprehensive analysis and results
- Agent Comparison Demo - Side-by-side performance comparison
- Technical Deep Dive - Detailed mechanism explanation
- Live Experiment Run - Complete 100-episode experiment
This project explores cutting-edge concepts in AI:
- Meta-Learning
