Neighborhood restrictions in geographic IR

Steven Schockaert, Martine De Cock
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07

Fuzzy Core DBScan Clustering Algorithm [chapter]

Gloria Bordogna, Dino Ienco
2014 Communications in Computer and Information Science  
In this work we propose an extension of the DBSCAN algorithm to generate clusters with fuzzy density characteristics.  ...  In order to deal with this issue, we propose Approx Fuzzy Core DBSCAN that applies a soft constraint to model different densities, thus relaxing the rigid assumption used in the original algorithm.  ...  Having fuzzy clusters allows generating isolines footprints.

StreamSoNG: A Soft Streaming Classification Approach [article]

Wenlong Wu, James M. Keller, Jeffrey Dale, James C. Bezdek
2021 arXiv   pre-print
In this paper, we propose a new streaming classification algorithm that uses Neural Gas prototypes as footprints and produces a possibilistic label vector (of typicalities) for each incoming vector.  ...  Examining most streaming clustering algorithms leads to the understanding that they are actually incremental classification models.  ...  The footprints can additionally contain the structure of fuzzy rules [20] , [21] . In [22] , an evolving system was proposed that could add, remove, merge and split clusters.  ...
