2018-12-14 · Learning graphs from data: A signal representation perspective Xiaowen Dong*, Dorina Thanou*, Michael Rabbat, and Pascal Frossard The construction of a meaningful graph topology plays a crucial role in the effective representation, processing, analysis and visualization of structured data. When a natural choice of the graph is not This network is a representation learning technique for dynamic graphs. Graph neural network also helps in traffic prediction by viewing the traffic network as a spatial-temporal graph. 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. 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 Acknowledging the dynamic nature of knowledge graphs, the problem of learning temporal knowledge graph embeddings has recently gained attention.

Representation Learning on Graphs: Methods and Applications 摘要： 1 introduction 1.1 符号和基本假设 2 Embedding nodes 2.1 方法概览：一个编码解码的视角 讨论方法之前先提出一个统一的编码解码框架，我们首先开发了一个统一的编译码框架，它明确地构建了这种方法的多样性，并将各种方法置于相同的标记和概念基 2020-08-23 · Combining graph representation learning with multi-view data (side information) for recommendation is a trend in industry. Most existing methods can be categorized as multi-view representation fusion; they first build one graph and then integrate multi-view data into a single compact representation for each node in the graph. We focus on graph representation theory, aiming to automatically learn low-dimensional vector features for the simplest graph motifs, such as nodes and edges, in a way that would enable efficiently solve machine learning problems on graphs including node classification, link prediction, node clustering, while also tackling approaches for graph similarity and classification, and general aspects Learning latent representations of nodes in graphs is an important and ubiquitous task with widespread applications such as link prediction, node classification, and graph visualization. Previous methods on graph representation learning mainly focus on static graphs, however, many real-world graphs are dynamic and evolve over time.

Existing dynamic graph representation learning methods mainly fall into categories: temporal regularizers that enforce smoothness of node representations from adjacent snapshots [39, 40], and recur- Incontrast,representation learning approaches treat this problem as machine learning task itself, using a data-driven approach to learn embeddings that encode graph structure. Here we provide an overview of recent advancements in representation learning on graphs, reviewing tech-niques for representing both nodes and entire subgraphs. The construction of a meaningful graph topology plays a crucial role in the effective representation, processing, analysis, and visualization of structured data.
We leverage the GGNN’s ability to capture the topology of a graph and couple it with the LSTM encoder-decoder archi-tecture to capture the dynamics of the graph in order to cre-ate a dynamic network representation learning framework.

We describe existing models from an encoder-decoder perspective, Relational Representation Learning for Dynamic (Knowledge) Graphs: A Survey. Graphs arise naturally in many real-world applications including social networks, recommender systems, ontologies, biology, and computational finance. Traditionally, machine learning models for graphs have been mostly designed for 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
