In data mining literature, clustering plays an important role in bringing insights from a dataset that is actionable and provides important business directions. In simple language, clustering aims at bringing similar observations such as similar customers, similar patients, similar users, and so on. Clustering techniques are not limited to the domain of retail but can be extended to any domain. Segmentation is no more limited to the retail or e-commerce domain; it is also applicable to all domains and industries.
In this chapter, we are going to learn the following things:
In this chapter, you will know the basics of segmentation using various clustering methods. There are different methods used to perform clustering. The following examples clarify where and how clustering can be used to create segments that can be used to drive business value:
In standard data mining practice, customer segmentation is a way of dividing all customers into various subgroups relevant to the business and the business problem. That subgroup creation can be done either by using a subjective approach or by keeping the business objective in mind. In different industries, customer segmentation has different applications; for example, in retail, it is important to know the purchase behavior of customers, and different subgroups displaying unique purchase behavior is relevant to the business.
In the retail and e-commerce industry, offers, campaigns, loyalty programs, and discount strategies work based on the purchase behavior of the subgroup of customers. In other industries, sales, marketing strategy, and business plans run keeping in mind the customer's behavior, and the behavior drives the sales. That unique customer behavior one can be understood by performing segmentation on the data.
Having discussed various benefits of performing customer segmentation, it is important to know how to perform customer segmentation. There are two broad methods used to perform customer segmentation:
In this chapter, we will discuss the clustering-based approach to perform customer segmentation; the second method is not in the scope of this chapter.
