Efficient Aggregated Kernel Tests using Incomplete -statistics

A Schrab, I Kim, B Guedj… - Advances in Neural …, 2022 - proceedings.neurips.cc
We propose a series of computationally efficient, nonparametric tests for the two-sample,
independence and goodness-of-fit problems, using the Maximum Mean Discrepancy …

MMD-FUSE: Learning and combining kernels for two-sample testing without data splitting

F Biggs, A Schrab, A Gretton - Advances in Neural …, 2024 - proceedings.neurips.cc
We propose novel statistics which maximise the power of a two-sample test based on the
Maximum Mean Discrepancy (MMD), byadapting over the set of kernels used in defining it …

KSD aggregated goodness-of-fit test

A Schrab, B Guedj, A Gretton - Advances in Neural …, 2022 - proceedings.neurips.cc
We investigate properties of goodness-of-fit tests based on the Kernel Stein Discrepancy
(KSD). We introduce a strategy to construct a test, called KSDAgg, which aggregates …

A permutation-free kernel independence test

S Shekhar, I Kim, A Ramdas - Journal of Machine Learning Research, 2023 - jmlr.org
In nonparametric independence testing, we observe iid data {(Xi, Yi)} ni= 1, where X∈ Χ,
Y∈ Y lie in any general spaces, and we wish to test the null that X is independent of Y …

Using perturbation to improve goodness-of-fit tests based on kernelized stein discrepancy

X Liu, AB Duncan, A Gandy - International Conference on …, 2023 - proceedings.mlr.press
Kernelized Stein discrepancy (KSD) is a score-based discrepancy widely used in goodness-
of-fit tests. It can be applied even when the target distribution has an unknown normalising …
