Researchers have explored the learning dynamics of neural networks through a Fourier perspective, focusing on how they learn simpler features before more complex ones. Their work introduces a synthetic data model for translation-invariant inputs, demonstrating that while phase information alone is difficult for SGD to learn, power-law spectra can significantly accelerate this process. This approach provides mechanistic insights into the efficient learning of natural image distributions by deep neural networks. AI
