Elbow plot

In order to construct an elbow plot, we use the following code:

skplt.cluster.plot_elbow_curve(k_means, df, cluster_ranges=range(1, 20))plt.show()

This results in the following plot:

Elbow plot

The elbow plot is a plot between the number of clusters that the model takes into consideration along the x axis and the sum of the squared errors along the y axis.

In the preceding code, the following applies:

• We use the plot_elbow_curve() function with the k-means model, the data, and the number of clusters that we want to evaluate
• In this case, we define a range of 1 to 19 clusters

In the preceding plot, the following applies:

• It is ...
