Researchers have introduced the General Frequency Principle for Linear Approximation Classes, a new theoretical framework for understanding gradient descent training. The principle demonstrates that learner amplitude diminishes at higher frequencies during training, with conditions established for prioritizing lower frequencies. This principle does not guarantee faster convergence for lower frequencies but indicates that components with higher frequencies may take longer to learn, as validated by numerical experiments using Legendre and trigonometric bases.
