Cluster Analysis :
Cluster analysis is a method of grouping data objects into similar clusters or groups based on the similarity of their characteristics. It is a common technique used in data mining and machine learning to identify patterns and trends in large datasets.
One example of cluster analysis is in customer segmentation. In this scenario, a company may have a large database of customer information including demographics, purchasing habits, and other relevant characteristics. By using cluster analysis, the company can group their customers into distinct clusters based on their similarities, such as age, income, and purchasing behavior. This allows the company to better understand their customer base and tailor their marketing and sales strategies to each cluster.
Another example is in the analysis of gene expression data. In this case, cluster analysis can be used to group genes based on their expression levels across different samples or conditions. This can help identify genes with similar patterns of expression and potentially uncover new biological insights and relationships.
Overall, cluster analysis is a useful tool for discovering patterns and trends in large and complex datasets. By grouping data objects into similar clusters, it allows for better understanding and analysis of the data, and can be applied to a wide range of fields and applications.
