WebAbstract. Clustering based on Mutual K-nearest Neighbors (CMNN) is a classical method of grouping data into different clusters. However, it has two well-known limitations: (1) the clustering results are very much dependent on the parameter k; (2) CMNN assumes that noise points correspond to clusters of small sizes according to the Mutual K-nearest … chromatin fiber definition biologyWebSep 6, 2024 · K-nearest neighbor (KNN) is an algorithm that is used to classify a data point based on how its neighbors are classified.
