Acerca del Curso

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 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!

Challenging, but I feel that I learned a lot about programming. I'm looking forward to the UCSD intermediate programming course.

i have taken the whole specialization . so this review is for the whole specialization in general and for the capastone in particular.

the first and the second course is very easy . but the three remaining course are a little bit tough

so you will need to struggle and persist to complete the whole specialization especially the great project .

indeed the project is extremely great . you will use all the concept you have learned through this specialization to implement this great project .... but NOTE this specialization in general and the project in particular is NOT for a BEGINNER Programmer. it is for some one who has a background in programming . but overall you will learn a lot great stuff and concepts .. so have fun and enjoy programming .

I took the full Specialization, so I'm going write the same review for each of the 5 modules.

This is a great course, but it's not for beginners. They ask you to do a lot of coding, which is great since that's the only way to really gain proficiency. And the code they ask you to write is, in my opinion, pretty hard for someone new to coding. My hat's off to someone new to programming who makes it through the five modules.

So, thanks to Duke for putting together a great course. It was very good.

A great capstone for this specialization. One quibble is with the time estimates: all the reading assignments are marked as taking 10 minutes, which is probably true: just reading and understanding the reading will probably take that long. However, these assignments also task the student with writing code which is impossible to write in 10 minutes. Throughout the specialization, I often took between 1-7 hours to complete a reading/coding assignment. So the time commitment that they advertise is totally out of whack with reality.

That said, the material is mostly well-presented and interesting and the coding practice does give you good experience of what it is like working in Java.

Loved the project, but I am going to keep my review at 3 stars until there is a module to add capstone project to a web page. This would be super helpful for showing my work to a future employer!

I posted a question on the last week on the forum and never received an answer from a mentor. I had one response from another student which did not actually address the issue of my question and I had several views. And it wasn't as if there were a lot of questions posted. One course mentor could have easily answered all of them.

Great course. Somewhat easy relatively to other courses in this specialization.

Muy bueno, como introducción a la programación es muy completo y te abre las puertas para entender hasta otros lenguajes.

Highly recommended for anyone who wants to learn programming. I started from basically zero and learned a lot throughout the Specialization. The instructors do a great job of giving you enough information throughout the lectures without over loading you and making the assignments challenging enough that you feel like you are really getting the most out of your time.

Fantastic course! The instructors were very engaging, the lessons were varied and provided me with a wide variety of information in the field. After completely this course, I definitely feel much more confident working in this field.

The course design is really good. It is very hands-on. We get to build our own applications and test our applications in the quiz.

However I really hope if there can be more content. The course is rather short. The quality is good but the quantity is a bit insufficient.

I hope this course can be longer. Additional weeks can teach us how to convert BlueJ projects or Eclipse projects into EXE or host it in the cloud.

I also hope this course, in the future, teaches us to make graphical user interface, which would be a nice conclusion to whatever program that we make

I love the course. I really want to see more coming out of the Capstone project. I love the idea of the capstone building a recommender engine. However, to make it a complete package, I suggest a few things:

---Teach learners to use main() to create apps and convert to exe

---Teach learners, after the entire project codings, how to create an Applet out of the source codes

---Teach learners how to implement graphical user interface (make buttons, input field for movie queries)

---Teach learners how to, instead of getting data from a file in the folder, reads the data from a live-feed instead. That would enhance the learning experience of the course.

Thank you for all those. I'm a hungry guy so I suggest lots of things. However I'm very happy with the course designs. Very engaging and fruitful course series.

I like the exercises a lot and I suspect is a great thing that I leave the course with a lot of questions.
