Describe your change:

I added mean absolute percentage error to the loss function directory. I used matrix operations instead of for loops to enhance the performance of the algorithm. Looking forward to getting this pull request merged and also to acquire the hacktoberfest and hacktoberfest-accepted badge..

  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Documentation change?

Checklist:

  • I have read CONTRIBUTING.md.
  • This pull request is all my own work -- I have not plagiarized.
  • I know that pull requests will not be merged if they fail the automated tests.

All loss function files were consolidated into machine_learning/loss_functions.py in #10737. Could you move your new code into that file?

Could you move your function to the bottom of the file, right below mean_squared_logarithmic_error?
