Hello Everyone, I am learning data science from data science central. I am a beginner in this field and i want to know could anyone explain how to define the number of clusters in a clustering algorithm? As my research, The primary objective of clustering is to group together similar identities in such a way that while entities within a group are similar to each other, the groups remain different from one another.Can anyone know is it right information? I found this information here. Now i want to know more depth information about the Clustering Algorithm. Can anyone know about this query or about data science?
