Shared nearest neighbor graph
Webb11 apr. 2024 · The nearest neighbor graph (NNG) analysis is a widely used data clustering method [ 1 ]. A NNG is a directed graph defined for a set E of points in metric space. Each point of this set is a vertex of the graph. The directed edge from point A to point B is drawn for point B of the set whose distance from point A is minimal.

If ‘auto’, then True is used for mode=’connectivity’ and False for mode=’distance’. n_jobs int, default=None. The number of parallel jobs to run for neighbors search. None means 1 unless in a joblib.parallel_backend context. -1 means using all processors.
WebbThe proposed method represents the feature set as a graph with the dissimilarity between features as the edge weights. In the first phase, the features selected in the densest subgraph are considered the initial feature subset. In the second phase, shared nearest-neighbor-based clustering is applied to the feature set. WebbIn recent times, the shared nearest neighbor method (SNN) (Sharma and Verma 2024)has also been used to cluster high-dimensional data. The method utilizes a sampled density-based approach...
