On Explicit Super-Expressive Approximation for Neural Networks
Feng-Lei Fan, Ze-Yu Li, Chen-Yu Wang +1
In this work, we investigate the fixed-architecture neural network approximation with explicit parameter bounds and elementary activations. While prior work demonstrated super-expr…

On Expressivity of Height in Neural Networks
Feng-Lei Fan, Ze-Yu Li, Huan Xiong +1
In this work, beyond width and depth, we augment a neural network with a new dimension called height by intra-linking neurons in the same layer to create an intra-layer hierarchy,…
