- Abstract: The existing literature on knowledge graph completion mostly focuses on the
link prediction task. However, knowledge graphs have an additional
incompleteness problem: their nodes possess numerical attributes, whose values
are often missing. Our approach, denoted as MrAP, imputes the values of missing
attributes by propagating information across the multi-relational structure of
a knowledge graph. It employs regression functions for predicting one node
attribute from another depending on the relationship between the nodes and the
type of the attributes. The propagation mechanism operates iteratively in a
message passing scheme that collects the predictions at every iteration and
updates the value of the node attributes. Experiments over two benchmark
datasets show the effectiveness of our approach.

We consider the problem of modelling high-dimensional distributions and generating new examples of data with complex relational feature structure coherent with a graph skeleton.
The model we propose tackles the problem of generating the data features constrained by the specific graph structure of each data point by splitting the task into two phases.
In the first it models the distribution of features associated with the nodes of the given graph, in the second it complements the edge features conditionally on the node features.

The present work deals with uncovering anomalous edges in attributed graphs using two distinct formulations with complementary strengths.
The first relies on decomposing the graph data matrix into low rank plus sparse components to improve markedly performance.
The second broadens the scope of the first by performing robust recovery of the unperturbed graph, which enhances the anomaly identification performance.

Convolutional Network Approach [61.2786065744784]
In recommender systems, users and items are associated with attributes, and users show preferences to items.

We perform extensive experimentation on ten real-world datasets and show that the proposed feature map significantly improves the prediction accuracy as compared to baseline approaches on these datasets.
