Module 13: Specialisation

What you need first

• LightGBM and PR-AUC (Module 3), costs and calibration (Module 3 lesson 3), CNNs and the message classifier (Module 4 lesson 3) and error analysis (Module 6 lesson 2). The lab's Step 1 rebuilds Modules 1 to 12.
• No keys needed. One optional zero-shot comparison goes through ask() and is checked with scripted fakes; the Whisper snippet is a local step, not run here.
• If you already work in one specialist track and read its papers, go to the lab.
