Understanding Model Selection for Learning in Strategic Environments

Neural Information Processing Systems

The deployment of ever-larger machine learning models reflects a growing consensus that the more expressive the model class one optimizes over--and the more data one has access to--the more one can improve performance. As models get deployed in a variety of real-world scenarios, they inevitably face strategic environments.


Kernel Quadrature with Randomly Pivoted Cholesky Ethan N. Epperly and Elvira Moreno

Neural Information Processing Systems

This paper presents new quadrature rules for functions in a reproducing kernel Hilbert space using nodes drawn by a sampling algorithm known as randomly pivoted Cholesky. The resulting computational procedure compares favorably to previous kernel quadrature methods, which either achieve low accuracy or require solving a computationally challenging sampling problem.
