Welcome to this 1-hour project-based course on Building Similarity Based Recommendation System. In this project, you will learn how similarity based collaborative filtering recommendation systems work, how you can collect data for building such systems. You will learn what are some different ways you to compute similarity between users and recommend items based on products interacted by other similar users. You will learn to create user item interactions matrix from the original dataset and also how to recommend items to a new user who does not have any historical interactions with the items. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Reviews summary

Collaborative filtering course with rhyme implementation concerns

Students had mixed feelings about this course called "Building Similarity Based Recommendation System." Of its 7 reviews, 3 were very positive (4-5 stars) while the other 4 were negative (1-3). Students who liked the course appreciated the content, especially the projects, and found it particularly valuable to build a basic recommendation system from scratch. Those who disliked the course mainly pointed to technical issues with the Rhyme implementation. Specifically, they noted that the user interface was difficult to use, with a small workspace and limitations on video playback, and that the code used was sometimes complex and difficult to follow. Some reviewers were also frustrated with the final quiz, indicating that the correct answers were not always clear and that some questions could not be answered without looking them up in the exercise materials.
Course projects were valuable.
"Very nice projects! It gave me new insights about how to solve other problems"
Code was sometimes complex.
"The author often uses single lines of advanced code which can be difficult to follow if you aren't proficient in Python."
"This can be a nuisance or a learning opportunity, so it is up to you."
Rhyme implementation had technical issues.
"OK course, but an absolutely hideous implementation."
"You must use a virtual Windows machine in Rhyme."
"Rhyme is super annoying to use, and your actual workspace ends up being about the size of a mobile phone screen."
"If I wasn't desperate, I would have quit"
