WebThe bisecting k-means clustering algorithm combines k-means clustering with divisive hierarchy clustering. With bisecting k-means, you get not only the clusters but also the hierarchical structure of the clusters of data points. This hierarchy is more informative than the unstructured set of flat clusters returned by k-means. WebAfter learning enough about the fundamentals of python, I am pleased to be able to showcase my first project, an iterative visualization of the k-means clustering algorithm. To be able to actually see each iteration of the algorithm, I had to implement it myself instead of using SKLearn or something similar, so it was a great experience to ...
