GraphNVP: an Invertible Flow-based Model for Generating Molecular Graphs

no code implementations25 Sep 2019 Kaushalya Madhawa, katsuhiko Ishiguro, Kosuke Nakago, Motoki Abe

In contrast, our model is the first invertible model for the whole graph components: both of dequantized node attributes and adjacency tensor are converted into latent vectors through two novel invertible flows.

Exploring Partially Observed Networks with Nonparametric Bandits

1 code implementation19 Apr 2018 Kaushalya Madhawa, Tsuyoshi Murata

We formulate this problem as an exploration-exploitation problem and propose a novel nonparametric multi-arm bandit (MAB) algorithm for identifying which nodes to be queried.
