Downstream ML tasks can exploit the low-dimensional node embeddings by using them as the inputs to traditional machine learning models. These node-level downstream tasks include node classification, node clustering, recommendation, link prediction, and visualization. In this chapter, we discuss node embedding techniques. These techniques are based on one of random walk, matrix factorization, or deep learning. Further, some algorithms learn representations in an unsupervised setting while others learn in a supervised setting. We finally present comparison of these algorithms according to their performance on downstream tasks.
