MIT researcher Ziming Liu shared an online interactive tool designed to make reproducing classic AI training dynamics phenomena highly accessible. Users can simply click to train and watch how learning unfolds, tweak hyperparameters to observe changes in training dynamics, and see firsthand how weight decay controls the timing of grokking. The author emphasizes that many secrets of AI are hidden in training dynamics, and understanding them shouldn't be overly complex.
