no code implementations13 Jun 2020 Masahiro Fujisawa, Takeshi Teshima, Issei Sato, Masashi Sugiyama

Approximate Bayesian computation (ABC) is a likelihood-free inference method that has been employed in various applications.

Multilevel Monte Carlo Variational Inference

no code implementations1 Feb 2019 Masahiro Fujisawa, Issei Sato

We theoretically show that, with our method, the variance of the gradient estimator decreases as optimization proceeds and that a learning rate scheduler function helps improve the convergence.
