Two hours of graph engineering gold, captured on tape: Andrew Ng walks you through building agentic knowledge graphs from zero to real systems. 9:14 — your first agent that actually runs 33:11 — what “loops” really do (no hand-waving) 1:02:46 — turning loops into graphs that work 1:30:15 — agents that refactor and upgrade their own code 1:49:05 — the orchestration layer that runs it all end-to-end I’ve watched $500 “masterclasses” deliver less than what’s packed into this single video. Watch the lecture, then level up with my step-by-step graph engineering guide below.(CyrilXBT)
