Is Neural Network Better Than Ash at Detecting Team Rocket

Claim: a neural net beats Ash at spotting Team Rocket and explains why. Uses TensorFlow, TensorFlow.js, Google AutoML to train an edge object detector and a small 9‑layer CNN, trained on 158 images (87 Jesse, 71 James), achieves near‑perfect detection on many frames but fails on goofy or crowded shots. Builds an interactive web app with activation‑map sliders to show which filters (hair, beard, etc.) drive each prediction and it mostly works.
