Final thoughts

1. Final thoughts

Congratulations, you sure have come a long way! You've learned all about Unsupervised Learning, and applied the techniques to real-world datasets, and built your knowledge of Python along the way. In particular, you've become a whiz at using scikit-learn and scipy for unsupervised learning challenges. You have harnessed both clustering and dimension reduction techniques to tackle serious problems with real-world datasets, such as clustering Wikipedia documents by the words they contain, and recommending musical artists to consumers.

2. Congratulations!

You are now equipped to face a whole range of new challenges. Congratulations, once again, and keep coding!
