Data mining techniques can be applied rapidly on existing software and hardware platforms to increase the value of existing information resources, and can be integrated with new products and systems. Previously data analysis process often involved manual work and during which interpretation of data was...

This book provides a practical guide to unsupervised machine learning or cluster analysis using R software. Additionally, we developped an R package namedfactoextrato create, easily, a ggplot2-based elegant plots of cluster analysis results.
The complete data-mining process involves multiple steps, from understanding the goals of a project and what data are available toimplementingprocess changes based on the final analysis. The three key computational steps are the model-learning process, model evaluation, and use of the model. This ...
We discuss topological aspects of cluster analysis and show that inferring the topological structure of a dataset before clustering it can considerably enh
Agood cluster analysisaccurately groups data in a way that is useful and actionable. It uncovers real patterns in the data, leading to insights that drive decisions. Abad cluster analysis, on the other hand, creates misleading or arbitrary groups that don’t help solve a problem or add value...

3.4 Cluster analysis Cluster analysis as a widely used method in data mining of TCM can directly extract useful information from raw data, and its-generated result can clearly reflect the compatibility law and combination rule of different TCM therapeutic methods [18]. Hence, the 30 core herbs ...
Cluster analysis has wide applicability, including in unsupervised machine learning, data mining, statistics, Graph Analytics, image processing, and numerous physical and social science applications.Why Cluster Analysis? Data scientists and others use clustering to gain important insights from data by ...
