Transductive Kernels for Gaussian Processes on Graphs

no code implementations28 Nov 2022 Yin-Cong Zhi, Felix L. Opolka, Yin Cheng Ng, Pietro Liò, Xiaowen Dong

To address this, we present a novel, generalized kernel for graphs with node feature data for semi-supervised learning.

Gaussian Processes on Graphs via Spectral Kernel Learning

no code implementations12 Jun 2020 Yin-Cong Zhi, Yin Cheng Ng, Xiaowen Dong

We propose a graph spectrum-based Gaussian process for prediction of signals defined on nodes of the graph.

Bayesian Semi-supervised Learning with Graph Gaussian Processes

2 code implementations NeurIPS 2018 Yin Cheng Ng, Nicolo Colombo, Ricardo Silva

We propose a data-efficient Gaussian process-based Bayesian approach to the semi-supervised learning problem on graphs.

A Dynamic Edge Exchangeable Model for Sparse Temporal Networks

no code implementations11 Oct 2017 Yin Cheng Ng, Ricardo Silva

We propose a dynamic edge exchangeable network model that can capture sparse connections observed in real temporal networks, in contrast to existing models which are dense.

Scaling Factorial Hidden Markov Models: Stochastic Variational Inference without Messages

no code implementations NeurIPS 2016 Yin Cheng Ng, Pawel Chilinski, Ricardo Silva

Factorial Hidden Markov Models (FHMMs) are powerful models for sequential data but they do not scale well with long sequences.
