Robustness of Baryon Acoustic Oscillations Measurements with Photometric Redshift Uncertainties
Keitaro Ishikawa, Tomomi Sunayama, Atsushi J. Nishizawa +2
We investigate the robustness of baryon acoustic oscillations (BAO) measurements with a photometric galaxy sample using mock galaxy catalogues with various sizes of photometric red…
Kernel Conditional Moment Constraints for Confounding Robust Inference
Kei Ishikawa, Niao He
We study policy evaluation of offline contextual bandits subject to unobserved confounders. Sensitivity analysis methods are commonly used to estimate the policy value under the wo…
Efficient Debiased Evidence Estimation by Multilevel Monte Carlo Sampling
Kei Ishikawa, Takashi Goda
In this paper, we propose a new stochastic optimization algorithm for Bayesian inference based on multilevel Monte Carlo (MLMC) methods. In Bayesian statistics, biased estimators o…
Multilevel Monte Carlo estimation of log marginal likelihood
Takashi Goda, Kei Ishikawa
In this short note we provide an unbiased multilevel Monte Carlo estimator of the log marginal likelihood and discuss its application to variational Bayes.
