Particle-MALA and Particle-mGRAD: Gradient-based MCMC methods for high-dimensional state-space models

1 code implementation26 Jan 2024 Adrien Corenflos, Axel Finke

In experiments, for both highly and weakly informative prior dynamics, our methods substantially improve upon both CSMC and sophisticated 'classical' MCMC approaches.

On importance-weighted autoencoders

no code implementations24 Jul 2019 Axel Finke, Alexandre H. Thiery

The importance weighted autoencoder (IWAE) (Burda et al., 2016) is a popular variational-inference method which achieves a tighter evidence bound (and hence a lower bias) than standard variational autoencoders by optimising a multi-sample objective, i. e. an objective that is expressible as an integral over $K > 1$ Monte Carlo samples.
