🔬 How It Works

The Science Behind Smart Learning

🧠 Spaced Repetition Algorithm (SM-2 Modified)

Our implementation of the SuperMemo SM-2 algorithm with enhancements:

1. Initial Learning: New questions appear immediately
2. Success Tracking: Correct answers → longer intervals
3. Difficulty Adjustment: Wrong answers → reset to short intervals
4. Ease Factor: Adapts based on response time and accuracy

# Example: Adaptive interval calculation
if correct_answer:
    if repetition == 0:
        interval = 1 day
    elif repetition == 1:
        interval = 6 days
    else:
        interval = previous_interval × ease_factor

ease_factor = max(1.3, ease_factor + (0.1 - (5-quality) × (0.08 + (5-quality) × 0.02)))

🎯 Error Focus Algorithm

• Difficulty Score: (1 - success_rate) × 100 + (3.0 - ease_factor) × 20
• Priority Ranking: Questions sorted by difficulty for targeted practice
• Smart Selection: Balances new content with error-prone material

🔧 Advanced Configuration

⚙️ Customizing the Algorithm

You can modify the spaced repetition parameters in SpacedRepetition.py:

# Adjust these values to customize learning behavior
INITIAL_EASE_FACTOR = 2.5    # Starting difficulty
MIN_EASE_FACTOR = 1.3        # Minimum difficulty
MAX_INTERVAL = 365           # Maximum review interval (days)
QUALITY_THRESHOLD = 3        # Minimum quality for success

📊 Analytics Customization

Modify analytics in ErrorAnalyzer.py:

# Customize difficulty thresholds
MASTERY_THRESHOLD = 0.8      # 80% success rate for mastery
DIFFICULTY_THRESHOLD = 0.5   # 50% success rate for difficulty
SLOW_RESPONSE_TIME = 20      # Seconds for "slow" classification
