A new cluster validity index using maximum cluster spread based compactness measure
M. Arif Wani,Romana Riyaz +1 more
TL;DR: A new compactness measure is introduced that depicts the typical behaviour of a cluster where more points are located around the centre and lesser points towards the outer edge of the cluster and a novel penalty function is proposed for determining the distinctness measure of clusters.
Journal ArticleDOI
A novel point density based validity index for clustering gene expression datasets
M. Arif Wani,Romana Riyaz +1 more
TL;DR: A new cluster validity index (ARPoints index) for the purpose of cluster validation is proposed and a new approach to determine the compactness measure and distinctness measure of clusters is presented.
Proceedings ArticleDOI
Local and Global Data Spread Based Index for Determining Number of Clusters in a Dataset
Romana Riyaz,M. Arif Wani +1 more
TL;DR: A new cluster validity index (ARSpread index) is proposed for the purpose of cluster validation and determining number of clusters present in a dataset and shows that the proposed new index performs better than the commonly known indices.
Proceedings ArticleDOI
Cluster based approach for mining patterns to predict wind speed
TL;DR: A cluster based approach for extracting patterns in meteorological data that aid in predicting wind speed patterns is proposed and extensive experimentation indicates that the proposed approach produces good results.
A comparative study of various approaches for dialogue management
TL;DR: In this paper, a comparison between various available approaches for dialogue management is presented, and three different approaches to the dialog management are presented, i.e., natural language understanding, language generation and dialogue management.
