GraphTune: A Learning-based Graph Generative Model with Tunable Structural Features
share
Generative models for graphs have been actively studied for decades, and they have a wide range of applications. Recently, learning-based graph generation that reproduces real-world graphs has gradually attracted the attention of many researchers. Several generative models that utilize modern machine learning technologies have been proposed, though a conditional generation of general graphs is less explored in the field. In this paper, we propose a generative model that allows us to tune a value of a global-level structural feature as a condition. Our model called GraphTune enables to tune a value of any structural feature of generated graphs using Long Short Term Memory (LSTM) and Conditional Variational AutoEncoder (CVAE). We performed comparative evaluations of GraphTune and conventional models with a real graph dataset. The evaluations show that GraphTune enables to clearly tune a value of a global-level structural feature compared to the conventional models.
