New gradient descent method shows exponential convergence for over-parameterized models

Researchers have introduced Dual Space Preconditioned Gradient Descent, a novel method for optimizing models in over-parameterized regimes. This approach, which includes variations like Normalized Gradient Descent and Gradient Clipping, has been shown to converge exponentially to a solution that perfectly fits the data for linear models. The study also explores the implicit bias of these methods, demonstrating that the convergence point can depend on the step size and offering an approximate bias property that relates the preconditioned method's convergence to standard Gradient Descent.
