$k$-means clustering of extremes [PDF]

open access: yesElectronic Journal of Statistics, 2020
The $k$-means clustering algorithm and its variant, the spherical $k$-means clustering, are among the most important and popular methods in unsupervised learning and pattern detection. In this paper, we explore how the spherical $k$-means algorithm can be applied in the analysis of only the extremal observations from a data set.

Scalable k-means++

open access: yesProceedings of the VLDB Endowment, 2012
Over half a century old and showing no signs of aging, k -means remains one of the most popular data processing algorithms. As is well-known, a proper initialization of k -means is crucial for obtaining a good final solution.

Optimized K‐Means Algorithm [PDF]

open access: yesMathematical Problems in Engineering, 2014
The localization of the region of interest (ROI), which contains the face, is the first step in any automatic recognition system, which is a special case of the face detection. However, face localization from input image is a challenging task due to possible variations in location, scale, pose, occlusion, illumination, facial expressions, and clutter ...

Labouring in the Fields of the Past: Geographic Variation in New Deal Archaeology Across the Lower 48 United States

open access: yesBulletin of the History of Archaeology, 2015
New Deal archaeology survey and excavation projects across the lower 48 states exhibit considerable geographic variation in their nature and extent. Part of this variation can be linked to strong regional personalities, while other variation depended on ...
