Introducing the Recommender
You will start out the capstone project by taking a look at the features of a recommender engine. Then you will choose how to read in and organize user, ratings, and movie data in your program. The programming exercise will provide a check on your progress before moving on to the next step.

Simple Recommendations
Your second step in building a recommender will focus on making simple recommendations based on the average ratings that a movie receives. You'll also make sure that each recommended movie has a least a minimal number of user ratings before including it in your recommendations. Throughout this step you are encouraged you use your knowledge of the seven step process to design useful algorithms and successful programs to solve the challenges you will face.

Interfaces, Filters, Database
In your third step, you will be encouraged to use interfaces to rewrite your existing code, making it more flexible and more efficient. You will also add filters to select a desired subset of movies that you want to recommend, such as 'all movies under two hours long' or 'all movies made in 2012'. You'll also make your recommendation engine more efficient as you practice software design principles such as refactoring.

Weighted Averages
In your fourth step, you will complete your recommendation engine by finding users in the database that have similar ratings and weighting their input to provide a more personal recommendation for the users of your program. Once you complete this step, you could request ratings of movies from those you know, run your program, and give them recommendations tailored to their own interests and tastes!

JAVA PROGRAMMING: BUILD A RECOMMENDATION SYSTEM의 최상위 리뷰
SJ 제공2019년 10월 20일
Wonderful course learned a lot by making a recommendation system...but some assignments are bit hard to understand what they want from you but everything else is fine. Everyone must take this course
GW 제공2016년 2월 18일
I really like this approach to a final project. I learned a lot outside of the course by using a different, full-featured IDE and writing unit tests for my code. Pretty challenging!
JP 제공2020년 6월 2일
It’s a great project requiring good application of java. Some steps were hard to follow but understood them after some time. A good project to end a specialisation course. Cheers.
NT 제공2020년 11월 29일
This is a big challenge. If you decide to take the call, be prepared to learn a lot, struggle, have fun, and don't walk away once you get started. Great experience!
