Measures for clustering and anomaly detection in sets of higher dimensional ellipsoids
Sutharshan Rajasegarar,James C. Bezdek,Masud Moshtaghi,Christopher Leckie,Timothy C. Havens,Marimuthu Palaniswami +5 more
TL;DR: Two of the four measures, viz, Focal distance and Bhattacharyya distance, provide very similar and reliable bases for estimating cluster structures in sets of higher dimensional ellipsoids, that single linkage can successfully extract the indicated clusters, and that the model can find both first and second order anomalies in WSN data.
Proceedings ArticleDOI
On the extension of fuzzy k-means algorithms for detection of linear clusters
TL;DR: An extension of the fuzzy ISODATA (or fuzzy k-means) clustering algorithms, which attempt to recognize and compensate for their failure at detection of linear substructure in finite data sets, is discussed.
Proceedings ArticleDOI
Generation of prototypes from sets of linguistic summaries
TL;DR: This paper develops an approach to generate linguistic prototypes from a group of time blocks that represent a normal condition, then the set of summaries for new time blocks are compared to the prototypes to flag anomalous conditions, thereby reducing the burden on the human.

Edge detection using a fuzzy neural network
David Alan Kerr,James C. Bezdek +1 more
TL;DR: A method for training a standard feed forward, back propagation neural-like network using fuzzy label vectors whose performance goal is to produce edge images from standard imagery such as FLIR, video, and grey tone pictures is proposed.
