Web2 days ago · kmeans聚类算法是一种常用的无监督学习算法，可以将数据集分成k个不同的簇。在Python中，可以使用scikit-learn库中的KMeans类来实现鸢尾花数据集的聚类。鸢尾花数据集是一个经典的分类问题，包含了三个不同种类的鸢尾花，每个种类有50个样本。 WebFirst of all, k-means algorithm is able to find clusters in any n-dimensional data. If n is too big, it is better to use PCA but for n=3 that wouldn't necessarily add any value. The second thing that looks suspicious to me is that in the documentation for kmeans in scikit-learn, there is no compute_labels option, as seen here.
