• ✅ Both exported for use in optimization modules

Phase 2: Profiling Intro Sections ✓

• ✅ Module 14 (KV Caching → Memoization): Added O(n²) growth demonstration
• ✅ Module 17 (Quantization → Module 16): Added memory usage profiling
• ✅ Module 18 (Compression → Module 17): Added weight distribution analysis
• ✅ Module 16 (Acceleration → Module 18): Added CNN bottleneck profiling

Phase 3: Module Directory Reorganization ✓

Phase 4: Module Source File Updates ✓

• ✅ Module 14 (Profiling): Updated header, connection map, prerequisites

🚧 In Progress / Remaining Work

Phase 7: Book Chapter Content Updates (IN PROGRESS)

Need to update in each chapter file:

• Main heading (e.g., # 15. Memoization)
• YAML frontmatter:
  • title
  • prerequisites
  • next_steps
  • difficulty (Memoization: 3→2)
• Tier badge (if needed)
• Cross-references to other modules
• "What's Next?" sections

Files to update:

• 14-profiling.md (was 15)
• 15-memoization.md (was 14, "KV Caching")
• 16-quantization.md (was 17)
• 17-compression.md (was 18)
• 18-acceleration.md (was 16)
• 19-benchmarking.md (cross-references only)
• 09-spatial.md → rename to 09-convolutional-networks.md

Phase 8: Cross-Reference Cleanup (PENDING)

• Search for "Module 14" references (should now be context-dependent)
• Search for "Module 15" references
• Search for "KV Caching" references (update to "Memoization" where appropriate)
• Update "Next module" links

Phase 9: Testing (PENDING)

• Export test: tito export 14 (profiling)
• Export test: tito export 15 (memoization)
• Book build test: jupyter-book build book/
• Check for warnings/errors

Phase 10: Final Commits (PENDING)

Will commit in logical chunks:

1. Profiler enhancements
2. Module profiling intro sections
3. Module reorganization
4. Book chapter updates
5. TOC update
6. Cross-reference fixes

📊 Statistics

Total modules updated: 6 (14-19) Total chapter files renamed: 6 Total dev files updated: 6 Lines of code added: ~400+ (profiling intros) Files renamed: 12 (6 directories + 6 markdown files)

🎯 Key Design Decisions Made

1. Memoization vs KV Caching: Module renamed to emphasize general pattern, with KV caching as specific transformer application
2. Profiling First: Establishes measurement-first workflow for all optimizations
3. Quick Profiling Sections: Each optimization module (15-18) starts with profiling motivation
4. Module Order: Memoization → Quantization → Compression → Acceleration (specific to general, easy to hard)
5. Difficulty Adjustment: Memoization lowered from 3 to 2 (simpler caching pattern)
