📖 Usage Examples

1. Command-Line: Extract Topics from PDF

from optimized_universal_extractor import OptimizedUniversalExtractor

# Extract topics
extractor = OptimizedUniversalExtractor("doc/probability.pdf")
topics = extractor.extract_topics()
extractor.save_results()

print(f"Extracted {len(topics)} topics")
# Output: Extracted 42 topics

2. Command-Line: Generate Curriculum

from llm_enhanced_curriculum_generator import EnhancedLLMCurriculumGenerator

generator = EnhancedLLMCurriculumGenerator()
curriculum = generator.generate_curriculum(learning_query="probability theory")

print(f"Created {len(curriculum['modules'])} modules")
# Output: Created 4 modules

3. Command-Line: Generate Quiz

from llm_quiz_generator import LLMQuizGenerator

quiz_gen = LLMQuizGenerator()
quiz = quiz_gen.generate_quiz(
    module_name="Introduction to Probability",
    topic_title="Random Variables",
    num_questions=5,
    difficulty="medium"
)

print(f"Generated {len(quiz['questions'])} questions")
# Output: Generated 5 questions

4. Dashboard: Full Learning Workflow

Step 1: Upload & Extract

  1. Open dashboard: streamlit run dashboard.py
  2. Upload PDF textbook
  3. System automatically extracts topics

Step 2: Generate Curriculum

  1. Enter learning goal: "probability and statistics"
  2. Click "Generate Curriculum"
  3. System creates personalized learning path

Step 3: Learn & Quiz

  1. Click topic to view theory
  2. Complete learning
  3. Click "Generate Quiz"
  4. Answer questions

Step 4: Adaptive Learning

  1. Submit quiz answers
  2. System analyzes performance:
    • Score: 45% → Low performance detected
    • Trend: Declining (85% → 70% → 45%)
    • Weak topics: ["Probability Axioms", "Sample Spaces"]
  3. Curriculum automatically adapts:
    • ✅ Adds "📚 Review: Probability Axioms"
    • ✅ Adds "📚 Review: Sample Spaces"
    • ✅ Adjusts difficulty to "easy"
  4. Student sees notification:
    🔄 Curriculum Adapted!
    Based on your declining performance (47.6% average),
    we've added review materials for foundational concepts.
    

🎯 Real-Time Adaptation System

How It Works

1. QUIZ SUBMISSION
   └─> Student answers questions
   └─> Score calculated: 45%

2. PERFORMANCE ANALYSIS
   └─> Last 5 quizzes analyzed: [50%, 48%, 55%, 40%, 45%]
   └─> Average: 47.6%
   └─> Trend: Declining (scores decreasing)
   └─> Weak topics identified: 2 topics

3. ADAPTATION DECISION (AI Agent)
   └─> Decision type: inject_remedial
   └─> Priority: HIGH
   └─> Actions:
       ├─> Add 2 review topics
       ├─> Adjust difficulty: medium → easy
       └─> Rerank remaining topics

4. CURRICULUM UPDATE
   └─> Before: 3 topics
   └─> After: 5 topics (2 new review topics added)
   └─> Topics reordered by priority

5. REAL-TIME NOTIFICATION
   └─> Redis pub/sub broadcast
   └─> Dashboard updates immediately
   └─> Student sees: "🔄 Curriculum Adapted!"

Adaptation Strategies

Performance Pattern Adaptation Action Example
Low Score (< 60%) Inject remedial content Add "📚 Review: Basic Concepts"
Declining Trend Adjust difficulty + Add reviews Change "hard" → "easy" + Add 3 review topics
High Score (> 90%) Skip ahead Mark module complete, unlock advanced content
Consistent Weak Topic Rerank topics Move struggling topic to front of queue
Rapid Improvement Increase difficulty Change "easy" → "medium"

🧪 Testing & Verification

Run Tests

# Test curriculum adaptation logic
cd server
python -c "
from agent.curriculum_adapter import CurriculumAdapter
adapter = CurriculumAdapter()
print('✅ Curriculum Adapter initialized successfully')
"

# Test vector store
python db/vector_store.py

# Test PDF extraction
python optimized_universal_extractor.py

# Test curriculum generation
python llm_enhanced_curriculum_generator.py

Verify Adaptation is Working

# Run the simulation test
cd server
python -c "
import json
import copy

curriculum = {
    'modules': [{
        'title': 'Test Module',
        'topics': [
            {'title': 'Topic 1'},
            {'title': 'Topic 2'}
        ]
    }]
}

# Simulate adding remedial content
module = curriculum['modules'][0]
remedial = {
    'title': '📚 Review: Basics',
    'type': 'remedial'
}
module['topics'] = [remedial] + module['topics']

print('Before: 2 topics')
print(f'After: {len(module[\"topics\"])} topics')
print('✅ Adaptation logic working!')
"

Expected output:

Before: 2 topics
After: 3 topics
✅ Adaptation logic working!

🚨 Troubleshooting

Common Issues

Issue: "Module not found" errors

# Solution: Ensure you're in the server directory
cd server
streamlit run dashboard.py

Issue: Azure OpenAI authentication errors

# Solution: Check .env file has correct credentials
cat .env | grep AZURE_OPENAI
# Verify keys are not expired

Issue: ChromaDB persistence warnings

# Solution: ChromaDB auto-creates directories, warnings are safe to ignore
# Or manually create:
mkdir -p data/chromadb

Issue: Curriculum not updating after quiz

# Solution: This was a known bug, now fixed
# Ensure you have latest code:
git pull origin main

Issue: "Redis connection refused"

# Solution: Redis is optional, system works without it
# Or install and start Redis:
# sudo apt-get install redis-server
# redis-server
