Embed and Conquer: Scalable Embeddings for Kernel k-Means on MapReduce [PDF]

open access: yes, 2014
The kernel $k$-means is an effective method for data clustering which extends the commonly-used $k$-means algorithm to work on a similarity matrix over complex data structures.

Clustering with Spectral Norm and the k-means Algorithm [PDF]

open access: yes, 2010
There has been much progress on efficient algorithms for clustering data points generated by a mixture of $k$ probability distributions under the assumption that the means of the distributions are well-separated, i.e., the distance between the means of ...

Privacy-Preserving and Outsourced Multi-User k-Means Clustering [PDF]

open access: yes, 2014
Many techniques for privacy-preserving data mining (PPDM) have been investigated over the past decade. Often, the entities involved in the data mining process are end-users or organizations with limited computing and storage resources.

Assessing Cloud Segmentation in the Chromacity Diagram of All-Sky Images

open access: yesRemote Sensing, 2020
All-sky imaging systems are currently very popular. They are used in ground-based meteorological stations and as a crucial part of the weather monitors for autonomous robotic telescopes. Data from all-sky imaging cameras provide important information for

Semi-supervised k-means++

open access: yesJournal of Statistical Computation and Simulation, 2017
Traditionally, practitioners initialize the {\tt k-means} algorithm with centers chosen uniformly at random. Randomized initialization with uneven weights ({\tt k-means++}) has recently been used to improve the performance over this strategy in cost and run-time.

Faster K-Means Cluster Estimation

open access: yes, 2017
There has been considerable work on improving popular clustering algorithm `K-means' in terms of mean squared error (MSE) and speed, both. However, most of the k-means variants tend to compute distance of each data point to each cluster centroid for ...
