Ranked differences Pearson correlation dissimilarity with an application to electricity users time series clustering
Chutiphan Charoensuk, Nathakhun Wiroonsri
Time series clustering is an unsupervised learning method for classifying time series data into groups with similar behavior. It is used in applications such as healthcare, finance…
A Bayesian cluster validity index
Nathakhun Wiroonsri, Onthada Preedasawakul
Selecting the appropriate number of clusters is a critical step in applying clustering algorithms. To assist in this process, various cluster validity indices (CVIs) have been deve…
A correlation-based fuzzy cluster validity index with secondary options detector
Nathakhun Wiroonsri, Onthada Preedasawakul
The optimal number of clusters is one of the main concerns when applying cluster analysis. Several cluster validity indexes have been introduced to address this problem. However, i…
Clustering performance analysis using a new correlation-based cluster validity index
Nathakhun Wiroonsri
There are various cluster validity indices used for evaluating clustering results. One of the main objectives of using these indices is to seek the optimal unknown number of cluste…
