New Theory Shows ReLU Networks Benefit Exponentially From Depth

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new depth hierarchy for ReLU neural networks, demonstrating that each additional layer can exponentially reduce the number of neurons required. This breakthrough provides the first exponential separation for ReLU networks between adjacent fixed depths, specifically showing that a depth-3 network can achieve a certain function with significantly fewer neurons than any depth-2 network. The findings also offer an exact separation for a different function, where a depth-4 network is exponentially more efficient than a depth-3 network in terms of neuron count, even without weight restrictions.

IMPACT Establishes theoretical limits on neural network depth efficiency, potentially guiding future architectural designs.

    Every Layer Counts: An Exponential $L_2$ Depth Hierarchy for ReLU Networks

    arXiv:2608.23877v1 Announce Type: new Abstract: We prove a depth hierarchy for ReLU neural networks in which every additional ReLU layer can save exponentially many neurons. For every $\ell\geq 3$, a globally $[0,1]$-valued, $1$-Lipschitz function is realized by a depth-$\ell$ ne…
