コースについて

Mathematical Matrix Methods lie at the root of most methods of machine learning and data analysis of tabular data. Learn the basics of Matrix Methods, including matrix-matrix multiplication, solving linear equations, orthogonality, and best least squares approximation. Discover the Singular Value Decomposition that plays a fundamental role in dimensionality reduction, Principal Component Analysis, and noise reduction. Optional examples using Python are used to illustrate the concepts and allow the learner to experiment with the algorithms....

This Course content is very good and has good real-time examples. However, the Instructor should add a few videos on SVD, Maximum dilation, and Shrinkage and Direction of Maximum Dilation.

Thank you so much for giving me this opportunity to learn about matrix methods. This is helpful for my career and it is useful to all the beginners.

I came from a statistics background and had little experience explicitly interpreting Matrix Algebra as vectors more from the viewpoint of physics. It was an excellent review for me and I buzzed through it in a few days. After retiring I walked away from math, but the course made me remember why I went down that road. I recommend this class.

Pros and cons.

Sometimes it's hard to find in this course needed information to solve Assignments.

But you have to dig deeper from outside sources.

All readings are well chosen , and actually helped me understand.

The video quality needs to be improved. Better explanations to some sections could help along with explanantions to why answers were right or wrong in Assignments

The lectures could be more engaging and more topics could certainly be covered. This course on matrix is too sparse!! Also, strangely, there were no lectures for the final week - only links were provided for reading materials.

The topics of the course are good, nevertheless, the videos need explain all the topics in detail because, sometimes is hard to understand just reading the pdf materials.

Great examples and a lot of reading material. More videos on SVD would have helped

I found the course very unbalanced and without much effort applied to it.

Some parts were easy to understand - the worked examples helped a lot, while others, with less videos and based on links, required a lot of work, namely because of the specific terminology used.

Some of the critical links, namely for those sections without videos, are not working anymore, which definitely was a cause of major waste of time looking for additional resources, that were not even using some of the key terminology as that used in the assignments.

As cited by many other people, tutor(s) were not seen in any of the Forum Q&A.

This is not a course I would have taken had I known otherwise.

The python content in this course is almost zero. The only thing I learn useful is the section about "singualr value decomposition" (the only reason why I still give it a 2-star review). However there's no lecture about the topic but two papers to read through. The instructor only contributes to easy matrix stuff in first three weeks and convinently skip the harder content in week 5. The video is not instructive enough. Compare to other courses from Coursera, this course is poor in quality and preparation.

I wouldn't take this course. I would give a 1 star review if I wasn't so desperate for courses on linear algebra. I'm happy with the methods covered, and I found the first 2 weeks useful practice. However, it seems like the professor spent about 2 hours making the course. There's only about 30 minutes of content, with most of the learning coming from self-study of linked content on other websites. And week 5 doesn't even have any videos, just links to someone else's tutorials.

I did learn some things, so I hate to review the course harshly, but there were numerous errors in the quizzes which have been there for a long time (based on forum comments) and have not been addressed. If completely redone and troubleshot the course has potential but as it stands it really isn't up to Coursera standards.

the course topics are interesting, unfortunately a video on week 5 would have been very important.

there are several errors in the test which made completing the test unnecessary difficult.

Fun course, but feels like they don't supply all the necessary information for the latter section of the course. Had to supplement with self found information to complete this course.

I thought this course was not very helpful, especially in the SVD section. Just giving a bunch of readings on SVD was not very useful. I expected more of an explanation.

T​his course is obviously home-made. Why the University of Minnesota permitted it to be uploaded to the Coursera platform is something I cannot fathom; it is by far the shabbiest course I have ever reviewed at Coursera. All topics presented are covered much more effectively in other courses. For example, SVD is covered by Nathan Kutz on his youtube AMATH channel, with applications. The economics of MOOCs is still a bit mysterious to me, but both Coursera and UMinn must financially benefit in at least some small way by having this content here, but why rely on Daniel Boley when we have Gilbert Strang, Nathan Kutz, Grant Sanderson, and many more teachers who actually care about imparting knowledge. If you look at his CV, Boley is research-oriented and obviously no longer cares a whit for teaching at this level. What we get is a review and a rather spotty one, at that, aimed at on-campus students in some other area at UMinn itself who have already mastered the topic.

This course is really bad. There are a lot of mistakes in reading material and exercises. Videos are poor and not clear. Teaching stuff doesn't respond. The first two weeks were fine, but others are not. The last week doesn't have any videos at all. The reading material is from different sites and books and has no structure.
