Mean-field limit from general mixtures of experts to quantum neural networks

This paper investigates the asymptotic behavior of mixture of experts (MoE) trained via gradient flow, establishing the propagation of chaos as the number of experts diverges and applying results to MoE generated by quantum neural networks.

The Mean-Field Limit in QML

This paper focuses on the theoretical underpinnings of quantum neural networks (QNNs), particularly examining their behavior in the mean-field limit. It explores how a system of many interacting quantum 'experts' can be approximated by a single representative 'particle' whose dynamics are governed by a partial differential equation. This allows for a deeper understanding of the scaling properties and training dynamics of large QNNs.
