clusternor (version 0.0-4)

A Parallel Clustering Non-Uniform Memory Access ('NUMA') Optimized Package

Description

The clustering 'NUMA' Optimized Routines package or 'clusternor' is a highly optimized package for performing clustering in parallel with accelerations specifically targeting multi-core Non-Uniform Memory Access ('NUMA') hardware architectures.

Functions in clusternor (0.0-4)

Kmeans

Perform k-means clustering on a data matrix.
Xmeans

Perform a parallel hierarchical clustering using the x-means algorithm
test_centroids

A small example of centroids of dim: (8,5) used as for micro-benchmarks of the clusternor package. The data are randomly generated.
MiniBatchKmeans

A randomized dataset sub-sample algorithm that approximates the k-means algorithm. See: https://www.eecs.tufts.edu/~dsculley/papers/fastkmeans.pdf
Skmeans

Perform spherical k-means clustering on a data matrix. Similar to the k-means algorithm differing only in that data features are min-max normalized the dissimilarity metric is Cosine distance.
test_data

A small dataset of dim: (50,5) used as for micro-benchmarks of the clusternor package. The data are randomly generated hence a clear number of clusters will be hard to find.
FuzzyCMeans

Perform Fuzzy C-means clustering on a data matrix. A soft variant of the kmeans algorithm where each data point are assigned a contribution weight to each cluster
Hmeans

Perform parallel hierarchical clustering on a data matrix.
KmeansPP

Perform the k-means++ clustering algorithm on a data matrix.
