Researchers have developed new theoretical bounds for positive-weight kernel quadrature, a method that can outperform Monte Carlo techniques for smooth integrands. The study shows that optimizing quadrature weights under a positivity constraint is governed by the random convex hull of candidate samples, rather than simple averaging. This geometric insight leads to improved error bounds, achieving near $O(1/N)$ rates in certain spectral regimes and enabling Monte Carlo-beating performance. AI
