Why Neural Networks Need He Init, Clipping, and Momentum

I built an interactive tutorial that shows why neural networks fail without proper initialization and optimization techniques. Here's what you'll find:

  • Live code editor where you can watch networks train in real-time on x²
  • Step-by-step progression from linear models → ReLU → deep networks
  • Visual demonstrations of gradient explosion and dying ReLU problems
  • Interactive examples showing how each fix (He init, clipping, momentum) solves specific issues
  • Final section on vectorization and why frameworks use matrix operations

The approach is hands-on: start with a broken 2-layer network that hits NaN, then add fixes one at a time while watching the loss curve and predictions update. You can swap x² for cos(3x) or tweak hyperparameters to see how networks behave under different conditions.
