NOT ON THE CURRENT EDITION
This blip is not on the current edition of the radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the radarUnderstand more

DeepWalk is an algorithm that helps apply machine learning on graphs. When working on data sets that are represented as graphs, one of the key problems is to extract features from the graph. This is where DeepWalk can help. It uses SkipGram to construct node embeddings by viewing the graph as a language where each node is a unique word in the language and random walks of finite length on the graph constitutes a sentence. These embeddings can then be used by various ML models. DeepWalk is one of the techniques we're trialling on some of our projects where we've needed to apply machine learning on graphs.
