arXiv:2606.07414v1 Announce Type: new Abstract: Sparsity allows scaling model parameters without proportionally increasing computational cost. While mixture of experts (MoE) models are made increasingly sparse, individual experts typically remain large and dense. Here, we demonstrate that further increasing sparsity by shrinking each expert to consist of a single neuron and selecting a tiny fraction of many available neurons can improve compute efficiency and interpretability. Counterintuitively, the key to achieving both is removing the nonlinearity typically applied to the experts, resulting
The continuous push for more efficient and scalable AI models drives research into novel architectures, with sparsity increasing in relevance due to computational constraints.
This development could significantly enhance the compute efficiency and interpretability of large AI models, impacting the cost and capability of advanced AI systems.
Traditional large, dense individual experts in Mixture of Expert models are being challenged by extremely sparse, single-neuron experts that remove nonlinearities.
