cmeans

the cmeans algorithm module

Fuzzy clustering (also referred to as soft clustering) is a form of clustering in which each data point can belong to more than one cluster.

Clustering Or cluster analysis involves assigning data points to clusters (also called buckets, bins, Or classes), Or homogeneous classes, such that items in the same class Or cluster are as similar as possible, while items belonging to different classes are as dissimilar as possible. Clusters are identified via similarity measures. These similarity measures include distance, connectivity, And intensity. Different similarity measures may be chosen based on the data Or the application. > https://en.wikipedia.org/wiki/Fuzzy_clustering

knn

k-Nearest Neighbour Classification k-nearest neighbour classification for test set from training set. For each row of the test set, the k nearest (in Euclidean distance) training set vectors are found, and the classification is decided by majority vote, with ties broken at random. If there are ties for the kth nearest vector, all candidates are included in the vote.

K-NN Classifier in R Programming

K-Nearest Neighbor or K-NN is a Supervised Non-linear classification algorithm. K-NN is a Non-parametric algorithm i.e it doesn’t make any assumption about underlying data or its distribution. It is one of the simplest and widely used algorithm which depends on it’s k value (Neighbors) and finds it’s applications in many industries like finance industry, healthcare industry etc.
dbscan

DBSCAN density reachability and connectivity clustering

Generates a density based clustering of arbitrary shape as introduced in Ester et al. (1996). Clusters require a minimum no of points (MinPts) within a maximum distance (eps) around one of its members (the seed). Any point within eps around any point which satisfies the seed condition is a cluster member (recursively). Some points may not belong to any clusters (noise).
