Birch clustering example
WebBirch clustering uses a clustering feature tree (also calleda a characteristic feature tree), which we'll just call a tree. A has 3 components: - the number of data points: linear sum of points: : squared sum of points: So we have, Here is a small example of calculating a single : WebBIRCH clustering is a widely known approach for clustering, that has in ... for example for k-means, data stream, and density-based clustering. Clustering features used by BIRCH are simple summary statistics that can easily be updated with new data: the number of points, the linear
