Hierarchical recurrent neural networks for graph generation

Weba scalable framework for learning generative models of graphs. GraphRNN models a graph in an autoregressive (or recurrent) manner—as a sequence of additions of new nodes and edges—to capture the complex joint probability of all nodes and edges in the graph. In particular, GraphRNN can be viewed as a hierarchical model, where a graph-level WebHere we propose GraphRNN, a deep autoregressive model that addresses the above challenges and approximates any distribution of graphs with minimal assumptions about their structure.

WebGraphRNN has a node-level RNN and an edge-level RNN. The two RNNs are related as follows: Node-level RNN generates the initial state for edge-level RNN. Edge-level RNN generates edges for the new node, then updates node-level RNN state using generated results. This results in the following architecture. Notice that the model is auto-regressive ... WebDec 4, 2024 · Current leading autoregressive models fail to capture the permutation invariance nature of graphs for the reliance on generation ordering and have high time complexity.
