The Balance Iterative Reducing and Clustering using Hierarchies (BIRCH) algorithm works better on large data sets than the k-means algorithm. It breaks the data into little summaries that are clustered instead of the original data points. The summaries hold as much distribution information about the data points as possible. flushing pizza https://cansysteme.com
