StreamSoNG: A Soft Streaming Classification Approach

no code implementations1 Oct 2020 Wenlong Wu, James M. Keller, Jeffrey Dale, James C. Bezdek

Incoming data is normally assigned a crisp label (into one of the structures) and that structure's footprint is incrementally updated.

ConiVAT: Cluster Tendency Assessment and Clustering with Partial Background Knowledge

no code implementations21 Aug 2020 Punit Rathore, James C. Bezdek, Paolo Santi, Carlo Ratti

We demonstrate ConiVAT approach to visual assessment and single linkage clustering on nine datasets to show that, it improves the quality of iVAT images for complex datasets, and it also overcomes the limitation of SL clustering with VAT/iVAT due to "noisy" bridges between clusters.

A Scalable Framework for Trajectory Prediction

no code implementations10 Jun 2018 Punit Rathore, Dheeraj Kumar, Sutharshan Rajasegarar, Marimuthu Palaniswami, James C. Bezdek

To address these limitations, we propose a scalable clustering and Markov chain based hybrid framework, called Traj-clusiVAT-based TP, for both short-term and long-term trajectory prediction, which can handle a large number of overlapping trajectories in a dense road network.

Online Cluster Validity Indices for Streaming Data

no code implementations8 Jan 2018 Masud Moshtaghi, James C. Bezdek, Sarah M. Erfani, Christopher Leckie, James Bailey

An important part of cluster analysis is validating the quality of computationally obtained clusters.

Ground Truth Bias in External Cluster Validity Indices

no code implementations17 Jun 2016 Yang Lei, James C. Bezdek, Simone Romano, Nguyen Xuan Vinh, Jeffrey Chan, James Bailey

For example, NCinc bias in the RI can be changed to NCdec bias by skewing the distribution of clusters in the ground truth partition.
