Exercise

Log normalization in Python

Now that we know that the Proline column in our wine dataset has a large amount of variance, let's log normalize it.

numpy has been imported as np.

Instructions

  • Print out the variance of the Proline column for reference.
  • Use the np.log() function on the Proline column to create a new, log-normalized column named Proline_log.
  • Print out the variance of the Proline_log column to see the difference.
