Exercise

Recommend musical artists part II

Suppose you were a big fan of Bruce Springsteen - which other musical artists might you like? Use your NMF features from the previous exercise and the cosine similarity to find similar musical artists. A solution to the previous exercise has been run, so norm_features is an array containing the normalized NMF features as rows. The names of the musical artists are available as the list artist_names.

Instructions

100 XP
  • Import pandas as pd.
  • Create a DataFrame df from norm_features, using artist_names as an index.
  • Use the .loc[] accessor of df to select the row of 'Bruce Springsteen'. Assign the result to artist.
  • Apply the .dot() method of df to artist to calculate the dot product of every row with artist. Save the result as similarities.
  • Print the result of the .nlargest() method of similarities to display the artists most similar to 'Bruce Springsteen'.
