WebTo run the Kmeans () function in python with multiple initial cluster assignments, we use the n_init argument (default: 10). If a value of n_init greater than one is used, then K-means clustering will be performed using multiple random assignments, and the Kmeans () function will report only the best results. Here we compare using n_init = 1:
