Representation Learning on Graphs: Methods and Applications
dimensional visualization of node embeddings generated from this graph using the DeepWalk method (Section 2.2.2) [46]. The distances between nodes in the embedding space reflect proximity in the original graph, and the node embeddings are spatially clustered according to the different color-coded communities.

Lagrangian Duality for Dummies - Stanford Computer Science
www-cs.stanford.eduDavid Knowles November 13, 2010 We want to solve the following optimisation problem: minf 0(x) (1) such that f i(x) 0 8i21;:::;m (2) For now we do not need to assume convexity. For simplicity we assume no equality constraints, but all these results extend straightforwardly in that case. An obvious (but foolish) approach would be to achieve this ...
ImageNet: A Large-Scale Hierarchical Image Database
www-cs.stanford.edushow that ImageNet is a large-scale, accurate and diverse image database (Section2). In Section4, we present a few simple application examples by exploiting the current Ima-geNet, mostly the mammal and vehicle subtrees. Our goal is to show that ImageNet can serve as a useful resource for visual recognition applications such as object recognition,

Structural Deep Network Embedding - SIGKDD
www.kdd.orgDeepWalk [21] combined random walk and skip-gram to learn network representations. Although empirically effective, it lacks a clear objective function to articulate how to preserve the network structure. It is prone to preserving only the second-order proximity. However, our method designs an explicit objective function, which

In some experiments, DeepWalk’s representations are able to outperform all baseline methods while using 60% less training data. DeepWalk is also scalable. It is an online learning algo-
Link Prediction Based on Graph Neural Networks
proceedings.neurips.cca number of network embedding techniques have been proposed, such as DeepWalk [19], LINE [21] and node2vec [20], which are also latent feature methods since they implicitly factorize some matrices too [22]. Explicit features are often available in the form of node attributes, describing all kinds of side information about individual nodes.

Subsequently, semantic-aware ap-proaches, e.д., metapath2vec [4], were proposed to address node

arxiv.org(SC) [5] and DeepWalk (DW) [6]. Both SC and DW provide node embeddings Z. We use Eq. 4 (left side) to calculate scores for elements of the reconstructed adjacency matrix. We omit recent variants of DW [7, 8] due to comparable performance. Both SC and DW do not support input features. For VGAE and GAE, we initialize weights as described in [9].
