Constructive Universal Approximation by Infinite-Dimensional Neural Networks via Gaussian-Weighted Ridgelet Transform

Sho Sonoda, Luca Galimberti, Yuanchao Xu +2

Neural networks whose inputs are functions, as in operator learning, are usually shown to be universal by existence arguments, either by reduction to finite-dimensional networks or…

approximation results for infinite dimensional Neural Networks

Luca Galimberti

Leveraging the neural architectures which we introduced in arXiv:2109.13512v4, we show a global universal approximation theorem in the topology of , where a…

Learning from one graph: transductive learning guarantees via the geometry of small random worlds

Nils Detering, Luca Galimberti, Anastasis Kratsios +2

Since their introduction by Kipf and Welling in , a primary use of graph convolutional networks is transductive node classification, where missing labels are inferred within…

Neural networks in non-metric spaces

Luca Galimberti

Leveraging the infinite dimensional neural network architecture we proposed in arXiv:2109.13512v4 and which can process inputs from Fréchet spaces, and using the universal approxim…

Low-dimensional approximations of the conditional law of Volterra processes: a non-positive curvature approach

Reza Arabpour, John Armstrong, Luca Galimberti +2

Predicting the conditional evolution of Volterra processes with stochastic volatility is a crucial challenge in mathematical finance. While deep neural network models offer promise…
