New theory unifies deep neural network depth and complexity analysis

Researchers have developed a unified function space theory for deep fully connected neural networks, offering a new perspective on network depth and complexity. This framework accommodates a wide range of activation functions, unlike prior theories focused on specific types like ReLU. The theory establishes novel complexity bounds, indicating that function classes remain small even at arbitrary depths, and suggests that depth's expressivity benefits diminish when complexity is controlled by function space norms rather than parameter counts.
