Essentially, the goal is to learn vector representation for the nodes and edges of a knowledge graph taking time into account. representation dynamic Graph neural networks (GNNs) have emerged as a powerful tool for learning software engineering tasks including code completion, bug finding, and program repair. They benefit from leveraging program structure like control flow graphs, but they are not well-suited to tasks like program execution that require far more sequential reasoning steps than number of GNN Application: Contrastive Learning on Graphs • [1] Edge Prediction (GraphSAGE), NIPS’17: • Nearby nodes are positive, otherwise negative. • [2] Deep Graph Infomax (DGI), ICLR’19 / InfoGraph, NIPS’19 • Contrast local (node) and global (graph) representation. • Local and global pairs from the same/diﬀerent graphs … However, most contemporary representation learning methods only apply to static graphs while real-world graphs are often dynamic and change over time. Static representation learning methods are not able to update the vector representations when the graph changes; therefore, they must re-generate the vector representations on an updated static snapshot of the graph regardless of the extent of neural representation learning.

We present a survey that focuses on recent representation learning techniques for dynamic graphs. More precisely, we focus on reviewing techniques that either produce time-dependent embeddings that capture the essence of the nodes and edges of evolving graphs or use embed- In this survey, we review the recent advances in representation learning for dynamic graphs, including dynamic knowledge graphs. We describe existing models from an encoder-decoder perspective, categorize these encoders and decoders based on the techniques they employ, and analyze the approaches in each category.

Analyzing the rich information behind heterogeneous networks through network representation learning methods is signifcant for many application tasks such as link prediction, node classifcation and similarity research. As the networks evolve over times, the interactions among the nodes in networks make heterogeneous networks exhibit dynamic characteristics. However, almost all the existing

graphs by enabling each node to attend over its neighbors for representation learning in static graphs. As dynamic graphs usually have periodical patterns such as recurrent links or communities, atten-tion can focus on the most relevant historical snapshot(s), to facilitate future prediction. We present a novel Dynamic Self-Attention Network 2020-01-01 · Graph representation learning techniques can be broadly divided into two categories: (i) static graph embedding, which represents each node in the graph with a single vector; and (ii) dynamic graph embedding, which considers multiple snapshots of a graph and obtains a time series of vectors for each node. A Survey of Graph-Based Representations and Techniques for Scientiﬁc Visualization Chaoli Wang University of Notre Dame Abstract Graphs represent general node-link diagrams and have long been utilized in scientiﬁc visualization for data or-ganization and management. However, using graphs as a visual representation and interface for Research on graph representation learning has received a lot of attention in recent years since many data in real-world applications come in form of graphs.

Most graph representation learning methods use dimensionality reduction techniques to incorporate a node’s neighborhood information into a dense vector. They have been developed based on various approaches, including matrix factorization , , graph random walk , , edge modeling , and deep autoencoders , .

In this, the nodes are sensors installed on roads, the edges are measured by the distance between pairs of nodes, and each node has the average traffic speed within a window as dynamic input features. In this work, we study value function approximation in reinforcement learning (RL) problems with high dimensional state or action spaces via a generalized version of representation policy iteration (RPI). We consider the limitations of proto-value functions (PVFs) at accurately approximating the value function in low dimensions and we highlight the importance of features learning for an Research on graph representation learning has received a lot of attention in recent years since many data in real-world applications come in form of graphs. High-dimensional graph data are often in irregular form, which makes them more difficult to analyze than image/video/audio data defined on regular lattices.
