Newton's method converges faster for overparameterized neural networks

Researchers have developed a convergence analysis for Newton's method applied to neural networks in an overparameterized setting. Their work shows that as the number of hidden units increases, the training dynamics approach a deterministic limit governed by a "Newton neural tangent kernel" (NNTK). This NNTK allows for exponential convergence to a global minimum, overcoming the spectral bias issues that affect standard gradient descent, especially for high-frequency data components. AI
