Aggregate Your Data to the grain you want to cluster. Because I want to segment Accounts, I will aggregate the Opportunity Sum of Amount by Account. Suppose I have opportunity data with Account Region and Product information, and suppose I want to group accounts by their buying patterns using that data to perform white space analysis, this is how I might do it in a simplified example:ġ. Of course, clustering is not only applicable to accounts and contacts we have built a generic capability that you can apply on any data of your choosing.īehind the scene, when you apply a clustering transform on your data as part of a Data Prep recipe, the backend data processing platform applies a k-means algorithm on your chosen columns to calculate characteristics for each row, and then classify them into “clusters”. Practically, that means you can apply clustering to segment customers based on their behaviors so that you can analyze white space, predict churn, etc. The clustering transform allows you to discover relationships across data rows using the existing data in text or numerical formats. What is Clustering Transform in Data Prep?

In this blog, I will focus on the clustering transform and demonstrate how to conduct white space analysis using clustering in data prep recipes. In Summer ’21 release, they will become generally available.
