Pseudo-Centroid Clustering replaces the traditional concept of a centroid expressed as a center of gravity with the notion of a pseudo-centroid (or a coordinate free centroid) which has the advantage of applying to clustering problems where points do not have numerical coordinates (or categorical coordinates that are translated into numerical form). Such problems, for which classical centroids ...

This work addresses the problem of detecting local centroid paths, paths within an area of interest on a spatial network that has the highest concentration of activities. The KMR algorithm [1] is used to do clustering on the spatial network, and a new measure of the density of activities on a path, Activity Coverage Rate (ACR), is introduced to locate each such path. We use experiment results t...

In recent years we have seen a tremendous growth in the volume of text documents available on the Internet, digital libraries, news sources, and company-wide intranets. Automatic text categorization, which is the task of assigning text documents to pre-specified classes (topics or themes) of documents, is an important task that can help both in organizing as well as in finding information on th...

The Gibbs Centroid Sampler is a software package designed for locating conserved elements in biopolymer sequences. The Gibbs Centroid Sampler reports a centroid alignment, i.e. an alignment that has the minimum total distance to the set of samples chosen from the a posteriori probability distribution of transcription factor binding-site alignments. In so doing, it garners information from the f...

The worldline of a spinning test body moving in curved spacetime can be provided by the Mathisson-Papapetrou-Dixon equations when its centroid, i.e., center mass, is fixed spin supplementary condition (SSC). In present study, we continue exploration shifts between different centroids started recently published work [Iason Timogiannis et al., Phys. Rev. D 104, 024042 (2021).], henceforth paper I...

This paper presents an overview of Feature Extraction techniques for off-line recognition of isolated Gurumukhi numerals/characters. Selection of Feature Extraction method is probably the single most important factor in achieving high performance in pattern recognition. Our paper presents Zone based hybrid approach which is the combination of image centroid zone and zone centroid zone of numera...

-In Wireless sensor network (WSN), estimating the exact position of sensor node is an important research problem and its location accuracy impacts the efficiency of localization algorithms. In this paper improved centroid range free localization method is proposed and comparison with conventional centroid is done by varying different parameters such as anchor nodes, communication range and node...
