In this challenge we have given a directed social graph, and we have to predict missing links to recommend users (Link Prediction in graph)
Generated training samples of good and bad links from given directed graph and for each link got some features like no of followers, is he followed back, page rank, katz score, adar index, some svd fetures of adj matrix, some weight features etc. and trained ml model based on these features to predict link.
No low-latency requirement. Probability of prediction is useful to recommend ighest probability links.
