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.

Adjusting for Chance Clustering Comparison Measures

no code implementations3 Dec 2015 Simone Romano, Nguyen Xuan Vinh, James Bailey, Karin Verspoor

In particular, the Adjusted Rand Index (ARI) based on pair-counting, and the Adjusted Mutual Information (AMI) based on Shannon information theory are very popular in the clustering community.

A Framework to Adjust Dependency Measure Estimates for Chance

no code implementations27 Oct 2015 Simone Romano, Nguyen Xuan Vinh, James Bailey, Karin Verspoor

For example: non-linear dependencies between two continuous variables can be explored with the Maximal Information Coefficient (MIC); and categorical variables that are dependent to the target class are selected using Gini gain in random forests.
