Following module developer guidelines, added comprehensive visual diagrams:
1. Text-to-Numbers Pipeline (Introduction):
- Added full boxed diagram showing 4-step tokenization process
- Clear visual flow from human text to numerical IDs
- Each step explained inline with the diagram
2. Character Tokenization Process:
- Step-by-step vocabulary building visualization
- Shows corpus → unique chars → vocab with IDs
- Encoding process with ID lookup visualization
- Decoding process with reverse lookup
- All in clear nested boxes
3. BPE Training Algorithm:
- Comprehensive 4-step process with nested boxes
- Pair frequency analysis with bar charts (████)
- Before/After merge visualizations
- Iteration examples showing vocabulary growth
- Final results with key insights
4. Memory Layout for Embedding Tables:
- Visual bars showing relative memory sizes
- Character (204KB) vs BPE-50K (102MB) vs Word-100K (204MB)
- Shows fp32/fp16/int8 precision trade-offs
- Real production model examples (GPT-2/3, BERT, T5, LLaMA)
- Clear table format for comparison
Educational improvements:
- More visual, less text-heavy
- Clearer step-by-step flows
- Better intuition building
- Production context throughout
- Following module developer ASCII diagram patterns
Students now see:
- HOW tokenization works (not just WHAT)
- WHY different strategies exist
- WHAT the memory implications are
- HOW production models make these choices
- Bright yellow/orange gradient banner with construction icons (🚧⚠️🔨)
- Interactive controls for collapsing and dismissing the banner
- Responsive design that adapts to different screen sizes
- Clear messaging about active development and community feedback
- Proper spacing and professional appearance
- JavaScript functionality for persistent user preferences(https://claude.ai/code)
- This workflow was testing notebook conversion features
- Not required for website deployment
- Website deploys via deploy-book.yml on main branch
- Can re-enable later if needed for CI testing
- NotebooksCommand now checks modules/source/ for dev files
- Fixes 'No *_dev.py files found' error in CI
- Maintains backwards compatibility with flat structure
- Add NotebooksCommand to commands dictionary in main.py
- Command was imported but not registered
- Fixes 'invalid choice: notebooks' error in workflow
- Change 'tito module notebooks' to 'tito notebooks'
- The notebooks command is a top-level command, not a module subcommand
- Fixes workflow test failures
- Positional arguments cannot be in mutually exclusive groups in argparse
- Keep modules as positional argument, --all as optional flag
- Fixes CLI initialization error in GitHub Actions
- Updated main README to prominently feature historical milestones (1957-2024)
- Added new 'Journey Through ML History' section to book navigation
- Created comprehensive milestones-overview.md chapter explaining the progression
- Updated intro.md with milestone achievements section
- Enhanced quickstart-guide.md with milestone unlock information
- Reflects working milestones/ directory structure with 6 historical demonstrations
- Clear progression: Perceptron (1957) → XOR (1969) → MLP (1986) → CNN (1998) → Transformers (2017) → Systems (2024)
- Emphasizes proof-of-mastery approach with real achievements

Track train vs test accuracy to detect overfitting:
Training Progress:
- Print both train and test accuracy every 5 epochs
- Show gap between train/test with indicator:
✓ Gap < 10%: Healthy generalization
⚠️ Gap > 10%: Overfitting warning
Results Table (ACT 4):
- Train Accuracy + improvement
- Test Accuracy + improvement
- Overfitting Gap + status
- Training Time
Final Panel (ACT 5):
- Show test accuracy with gap
- Celebrate good generalization
Educational Value:
Students now see:
1. How to detect overfitting (growing train/test gap)
2. When model memorizes vs generalizes
3. Real ML systems track BOTH metrics
Example output:
Epoch 5/20 Loss: 1.234 Train: 85.0% Test: 82.0% ✓ Gap: 3.0%
Epoch 10/20 Loss: 0.891 Train: 90.0% Test: 87.0% ✓ Gap: 3.0%
This prepares them for regularization techniques (Dropout, etc.)
in later modules!
Changed from Panel to plain console.print with ASCII diagram.
All 4 milestones now follow identical format:
- console.print('[bold]🏗️ The Architecture:[/bold]')
- ASCII box diagram with arrows
- console.print('[bold]🔧 Components:[/bold]')
- Bullet list of components
This ensures visual consistency across all milestone demonstrations!
