Node Classification (Supervised)

Often, nodes in a graph come with some labels or tags. Some labels are usually missing when dealing with a vast graph database. Our task is to find or predict the missing labels using the knowledge from the available nodes. Yes, that's right! This sounds like a problem machine learning can solve.

Node classification is a task in which we build a predictive model, such as a binary classification task (in the case of two different types of labels) or a multiclass classification task (greater than two labels), to identify the missing cases.
