    Clustering in Data Mining - Code

    It is a data mining technique used to place the data elements into their related groups. Clustering is the process of partitioning the data (or objects) into the same class, The data in one class is more similar to each other than to those in other cluster. The process of partitioning data objects into subclasses is called as cluster. A cluster consists of data object with high inter ...

    As for data mining, this methodology divides the data that is best suited to the desired analysis using a special join algorithm. This analysis allows an object not to be part or strictly part of a cluster, which is called the hard partitioning of this type. However, smooth partitions suggest that each object in the same degree belongs to a cluster. More specific divisions can be .
