Split Hierarchical Variational Compression

no code implementations CVPR 2022 Tom Ryder, Chen Zhang, Ning Kang, Shifeng Zhang

Secondly, we define our coding framework, the autoregressive initial bits, that flexibly supports parallel coding and avoids -- for the first time -- many of the practicalities commonly associated with bits-back coding.

iFlow: Numerically Invertible Flows for Efficient Lossless Compression via a Uniform Coder

no code implementations NeurIPS 2021 Shifeng Zhang, Ning Kang, Tom Ryder, Zhenguo Li

In this paper, we discuss lossless compression using normalizing flows which have demonstrated a great capacity for achieving high compression ratios.

The Neural Moving Average Model for Scalable Variational Inference of State Space Models

1 code implementation2 Oct 2019 Tom Ryder, Dennis Prangle, Andrew Golightly, Isaac Matthews

Variational inference has had great success in scaling approximate Bayesian inference to big data by exploiting mini-batch training.

Black-Box Inference for Non-Linear Latent Force Models

no code implementations21 Jun 2019 Wil O. C. Ward, Tom Ryder, Dennis Prangle, Mauricio A. Álvarez

Latent force models are systems whereby there is a mechanistic model describing the dynamics of the system state, with some unknown forcing term that is approximated with a Gaussian process.
