Gradient Descent, step by step
Every module goes deep — intuition, math, and visuals together.
Concepts that actually stick
Every module builds intuition first — with diagrams, animations, and worked examples — before going deep. No walls of text, no hand-waving. By the end of each module you understand the why, not just the what.
