This paper delves into the training solutions of two-layer neural networks that utilize smooth activation functions, such as the sigmoid function. The research outlines four core principles: Taylor series expansions, a strict partial order of knots, smooth-spline implementation, and a smooth-continuity restriction. By applying these principles, the paper proves universal approximation for arbitrary input dimensionality and offers explanations for the obtained training solutions, thereby demystifying the "black box" nature of the solution space and contributing to approximation theory.
