Scalable control variates for Monte Carlo methods via stochastic optimization

S Si, CJ Oates, AB Duncan, L Carin, FX Briol - International Conference on …, 2020 - Springer
Control variates are a well-established tool to reduce the variance of Monte Carlo
estimators. However, for large-scale problems including high-dimensional and large-sample …

A Stein goodness-of-fit test for directional distributions

W Xu, T Matsuda - International Conference on Artificial …, 2020 - proceedings.mlr.press
In many fields, data appears in the form of direction (unit vector) and usual statistical
procedures are not applicable to such directional data. In this study, we propose …
