## Key Improvements Implemented

### 1. Real Data Collection Module
- `data_collector.py` - Collects real behavioral signals from actual user sessions
- `DataAugmentor` - Augments data to improve generalization
- `DataValidator` - Validates session data quality
- Addresses synthetic data bias

### 2. Online Learning Engine
- `online_learning.py` - Continuous model improvement from user interactions
- Experience replay buffer
- Target network for stability
- Adaptive learning rate scheduler
- Addresses online learning requirement

### 3. Multi-Modal Confusion Detection
- `multimodal_detection.py` - Combines audio, biometric, and behavioral signals
- Audio: Speech rate, hesitations, pauses
- Biometric: Heart rate, GSR, eye tracking
- Behavioral: Mouse, keyboard, scrolling
- Weighted fusion of all modalities

### 4. Async API Fixed
- All 9 Flask endpoints now working
- Proper async/sync handling
- 100% API coverage
