The conclusions of this study are currently limited to the one-dimensional Gaussian kernel and compactly supported targets, and finite-particle guarantees under high-dimensional kernels and other kernel functions remain open problems.

UnverifiedImplications for practitioners: in the one-dimensional Gaussian kernel setting, the required number of particles can be estimated based on the compact support range of the target distribution, rather than relying purely on tuning.72% similarUnverifiedKernel methods have long faced a computational bottleneck when handling large-scale datasets—the size of the kernel matrix grows quadratically with the number of samples, making direct solution of kernel ridge regression almost infeasible.65% similarUnverifiedThe testing phase can typically only validate core atomic capabilities, making it difficult to cover their overall performance when combined, causing chain-degradation to be exposed only in the production environment.64% similarUnverifiedWhen the target distribution has finite support, the paper gives an explicit particle count threshold, beyond which no spurious local minima exist and every spurious stationary point is unstable.64% similarUnverified支持向量机的对偶问题通过拉格朗日对偶性转化后，计算复杂度只依赖于样本数而非特征维度，且数据仅以内积形式出现，为核技巧提供理论基础62% similar
