A solution to the previous exercise has been pre-loaded for you, so a Pipeline pipeline chaining TruncatedSVD with KMeans is available.

  • Import pandas as pd.
  • Fit the pipeline to the word-frequency array articles.
  • Predict the cluster labels.
  • Align the cluster labels with the list titles of article titles by creating a DataFrame df with labels and titles as columns. This has been done for you.
  • Use the .sort_values() method of df to sort the DataFrame by the 'label' column, and print the result.
  • Hit 'Submit Answer' and take a moment to investigate your amazing clustering of Wikipedia pages!
