New research explores neural network approximation for complex functional operators · 3 sources tracked

By PulseAugur Editorial · [3 sources] ·

Researchers are exploring advanced neural network architectures for approximating complex functions. One paper details how deep ReLU networks can approximate smooth functionals on infinite-dimensional Hilbert spaces, establishing error bounds based on coordinate decay and sensitivity. Another study introduces fractal interpolation functions using shallow neural network operators to preserve function smoothness, validated with Python experiments. A third paper investigates neural operators for nonlinear functionals on reproducing kernel Hilbert spaces, using point evaluations instead of integration for simpler architectures and deriving approximation rates and learning guarantees.
