Congratulations on completing the "Working with Machine Learning and AI Services on AWS" Learning Path. 

We hope you found this content both informative and engaging. Before we finish, we'll provide a quick recap of the concepts we've covered. We started with the course on Distributed Machine Learning, where we showed you how to build an ML cluster with Apache Spark installed. 

We trained a decision tree machine learning model using MLlib and Scala. Next, you were introduced to the Amazon Deep Learning AMI and TensorFlow with our hands-on lab. In this lab, you launched an instance of this AMI and used the TensorFlow framework. 

Following on from this, we introduced you to the first of Amazon's AI application services, Amazon Rekognition. This course showed you how to integrate computer version features onto your own applications. From here, you were able to use an Amazon Rekognition lab to perform automated image labeling. 

And finally, we covered Amazon Lex, another of Amazon's AI application services. This course showed you how you can build Chatbot style interfaces, and again integrate into your own applications.

Okay, so that brings this learning path to a close. We suggest that you perform the final assessment exam if you haven't done so already. This will give you an idea of which areas you might need to continue or review. Please feel free to contact us at support@cloudacademy.com if you have any questions and/or comments. 

Congratulations again on completing this learning path. You're well on your way to mastering machine learning on the AWS platform.
