Clustering on graph dataset assignment

Webgraph (called Instance Pivot Subgraph or IPS) per in-put sample and reformulated clustering as a link pre-diction problem where a link exists between two nodes when their identity labels are identical. They train the model on a large dataset and use the trained model on a smaller scale dataset to find the cluster assignments. WebOct 18, 2024 · After computing the silhouette coefficient of each point in the dataset, plot it to get a visual representation of how well the dataset is clustered into k clusters. The silhouette plot displays a measure of how close each point in one cluster is to points in the neighboring clusters and thus provides a way to assess parameters like the number ...
