arXiv:2606. 04980v1 Announce Type: new Abstract: Mixture-of-Experts (MoE) architectures scale model capacity through sparse expert activation, but their deployment remains memory-bound because all expert weights must reside in memory.
The paper presents a statistical framework for Mixture-of-Experts (MoE) models, treating them as localized aggregation systems. It derives oracle risk bounds that separate approximation, expert‑learning, and router‑estimation errors for both dense and sparse routing with evolving experts. The authors also analyze how sparse Top‑K routing balances computational cost with performance, interpret gating geometrically, and explain how shared experts can capture common predictive structure while allowing routed experts to focus on local residuals.

The paper introduces the Neural Function Minimizer (NFM), an iterative neural model that predicts the global minimum of a noisy one‑dimensional function from only twenty samples. It compares the NFM to two Set Transformers and classical zero‑query estimators, finding that all learned models outperform classical methods on held‑out data, with the NFM achieving the lowest error relative to the Gaussian‑process posterior argmin. The study also examines how different estimator outputs affect tie‑breaking between equally deep valleys and plans to release a benchmark and self‑checking harness.

arXiv:2510. 12744v2 Announce Type: replace-cross Abstract: We develop a unified statistical framework for softmax-gated Gaussian mixture of experts (SGMoE) that addresses three long-standing obstacles in parameter estimation and model selection: (i) non-identifiability of gating parameters up to common translations, (ii) intrinsic gate-expert interactions that induce coupled differential relations in the likelihood, and (iii) the tight numerator-denominator coupling in the softmax-induced conditional density.
