TL;DR: Decomposition of one-layer neural networks via the infinite sum of reproducing kernel Banach spaces
Abstract: In this paper, we define the sum of RKBSs using the characterization theorem of RKBSs and show that the sum of RKBSs is compatible with the direct sum of feature spaces. Moreover, we decompose the integral RKBS $\mathcal{F}\_{\sigma}(\mathcal{X},\Omega)$ into the sum of $p$-norm RKBSs $\\{\mathcal{L}\_{\sigma}^{1}(\mu\_{i})\\}\_{i\in I}$. Finally, we provide some applications to enhance the structural understanding of the integral RKBS class.
