arXiv:2510.04500v2 Announce Type: replace Abstract: This work demonstrates how increasing the number of neurons in a network without increasing its total number of non-zero parameters improves performance. We show that this gain corresponds with a decrease in interference between multiple features that would otherwise share the same neurons. On symbolic Boolean tasks, splitting each neuron into sparser sub-neurons with knowledge of the clauses systematically reduces polysemanticity metrics and yields higher task accuracy. Notably, even random splits of neuron weights approximate these gains, i
This research provides a new architectural approach in neural nets, emerging as the field continues to seek more efficient and performant models.
It suggests a path to significant performance improvements in AI models without increasing parameter count, which could democratize access to advanced AI capabilities.
The focus might shift from raw parameter count as the primary metric of model strength to more nuanced architectural considerations like neuron expansion and polysemanticity reduction.

AI models could achieve higher accuracy and efficiency for given computational resources.
This could lead to a proliferation of more capable AI applications on resource-constrained devices.
The development of specialized hardware designed to exploit expanded, sparser neuron architectures might accelerate.
