Neural Flow Operators can Approximate any Operator: Abstract Frameworks and Universal Approcimations
arXiv:2605.22557v1 Announce Type: new Abstract: We introduce an abstract neural flow framework for neural networks and neural operators. The framework contains two continuous-depth models, namely neural flows with composition and separation structures, and covers both finite-dimensional function approximation and infinite-dimensional operator approximation. We prove well-posedness and universal approximation properties for the corresponding neural flows, including, to the best of our knowledge, the first universal approximation result for flow-based models between infinite-dimensional spaces.
This research is emerging as the field of AI is rapidly advancing, particularly in the understanding and application of neural networks and operators in complex systems.
A universal approximation theorem for flow-based models in infinite-dimensional spaces significantly expands the theoretical foundation and potential capabilities of AI, particularly for highly complex, real-world operators.
The theoretical understanding of what neural networks can model is broadened, potentially enabling more powerful and robust AI systems for tasks involving continuous and complex data domains.
