Hyperbolic Graph Convolutional Networks | Geometric ML Paper Explained

Hyperbolic GCNs give exceptional results for the class of scale-free/hierarchical/tree-like graphs. I dive deep into differential geometry theory and explain how the method works. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ✅ Paper: https://arxiv.org/abs/1910.12933 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⌚️ Timetable: 00:00 Intro - why the hyperbolic space? 04:00 Graph Convolutional Networks recap 08:50 Hyperbolic space and curvature theory 15:25 Geodesics, exp, and log maps 23:00 Mapping from Euclidean to hyperbolic space 26:35 Feature transform in hyperbolic space 32:47 Aggregregation on the hyperboloid manifold 35:25 Non-linear activation with different curvatures 36:30 Holistic overview of the method 38:20 Results, Ablations, and curvature analysis 41:00 Why does curvature help? 42:05 Outro ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 💰 BECOME A PATREON OF THE AI EPIPHANY ❤️ If these videos, GitHub projects, and blogs help you, consider helping me out by supporting me on Patreon!
