[MUSIC] Emily and I really hope you've enjoyed the course so far. We've really explored the foundations of machine learning on a wide range of domains with a range of different applications. And really touched many of the practical issues around deploying and building machine learning systems. And now in this closing module we're going to really summarize some of the concepts that we've learned. Talk about how to deploy these ideas, especially machine learning systems in production and then what's ahead in the specialization and in machine learning as a whole. Some really exciting stuff as we close off this first course. [MUSIC]
