NettetLink prediction is a key problem for network-structured data. Link prediction heuristics use some score functions, such as common neighbors and Katz index, to measure the likelihood of links. They have obtained wide practical uses due to their simplicity, interpretability, and for some of them, scalability. However, every Nettet11. jan. 2024 · I am doing a link prediction problem using the adamic_adar index. The dataset is a grid network (edgelist with 1000 links). I randomly selected 80% (800) of the edges from the observed dataset. I need to select the highest 200 predicted links from preds as below and also calculate the precision ratio. I dont know what to do next.

NettetLink prediction is a common machine learning task applied to graphs: training a model to learn, between pairs of nodes in a graph, where relationships should exist. More precisely, the input to the machine learning model are examples of node pairs. During training, the node pairs are labeled as adjacent or not adjacent.
