A Dynamical Model of Neural Scaling Laws

Second part of a two-part blog post covering recent findings from the authors

By: Blake Bordelon, Alex Atanasov, and Cengiz Pehlevan

By analyzing the dynamics of a random feature model trained with gradient descent, the authors reproduce and explain many observations about neural scaling laws, including compute optimal scaling of model size and training time.
