Graphs can be classified into …
Web3.2 Missing Data Problem as a Graph Prediction Task The key insight of this paper is to represent the feature matrix with missing values as a bipartite graph. Then the feature imputation problem and the label prediction problem can naturally be formulated as node prediction and edge prediction tasks (Figure 1). Feature matrix as a bipartite graph.
