Backpropagation Explained as Dynamic Programming with Animated Demo
An animated visualization shows backpropagation reuses error values across layers, making gradient computation efficient. The demo uses React, Framer Motion, and Web Audio API to illustrate one training step. The key insight: storing and reusing derivatives is identical to dynamic programming, not just chain rule application.

The animation elegantly demystifies why backpropagation is computationally feasible, but the real-world challenge remains scaling this to billions of parameters across distributed systems.
