À propos du cours

Ever wonder how Netflix decides what movies to recommend for you? Or how Amazon recommends books? We can get a feel for how it works by building a simplified recommender of our own! In this capstone, you will show off your problem solving and Java programming skills by creating recommender systems. You will work with data for movies, including ratings, but the principles involved can easily be adapted to books, restaurants, and more. You will write a program to answer questions about the data, including which items should be recommended to a user based on their ratings of several movies. Given input files on users ratings and movie titles, you will be able to: 1. Read in and parse data into lists and maps; 2. Calculate average ratings; 3. Calculate how similar a given rater is to another user based on ratings; and 4. Recommend movies to a given user based on ratings. 5. Display recommended movies for a given user on a webpage....

I really enjoyed this course, it was fantastic, the lecturers explained well.

Please come and enroll for this course, it was great and there was alot of interaction between other learners

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!

This is definitely a good and useful capstone but a 5-star rating is maybe too much. The main disadvantage of the course is that it has not enough support from students or mentors in the discussion rooms. The second disadvantage is that building continuously on the top of other classes adds complexity to the final project. For one who has finished all 4 previous courses, I definitely recommend that course as a must.

The course should be supported by the creators and further improved because this is one of the best specializations. The concept of it is to guide you from a non-programmer to a junior java developer by focusing on fundamental structures of programming.

This whole series really challenged me but I've learned more from this course than any of my other previous attempts to learn programming. I feel a lot more confident now taking on more challenges in software development. There were some homework problems near the end that could have been explained a little better (sometimes I was overthinking it). I also felt that perhaps instead of BlueJ, I would've liked to use something like Eclipse in order to better understand the main() function. All in all, I would definitely recommend this course for those interested in programming or wanting to learn Java.

It was a good summary of everything that was taught. However due to the long gap from the initial exposure to CSV parsing and html table to now, it was not easy accomplishing the tasks as a lot of external reference was required to solve the problems given. Some of the exercises were phrased sort of ambiguously which made it hard to comprehend

The capstone was helpful for learning core software development practices. One can learn interface, abstraction, recommender system implementation and many more from the course. But, some instructions were pretty unclear and specially the peer reviewed assignment submission instruction was vague.

Most everything was good in this course. There were a few things that they didn't explain how to do ever throughout this 5 course program which was frustrating, but other students helped to fill the gaps on that part. Otherwise it was a great course that helped me put all of my knowledge to use.

Great conclusion to the courses in this Specialization. I would not recommend it for those already (very) familiar with Java but for those starting out with Java this Capstone is just difficult enough to be challenging yet not too easy.

Not enough submissions to review at the end. So not very friendly to self pace learning. Had to wait to review other people's submissions before complete the course, which may waste some time since it's paid by month.

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

We can view this project only using Duke's Platform. It would have been much better had this capstone guided us in deploying our project in the form of a web-app.

Course was good, great programming assignments.

But you can forget the discussion forums. No Mentors or Staff really present.

It's a great course. Students build a simple search engine step by step in the course.

The project is a little bit easy yet tedious, a good practice of using Java though.

Nice introduction to Java and programing principles in general
