Now i feel confident about pursuing machine learning courses in the future as I have learned most of the mathematics which will be helpful in building the base for machine learning, data science.

This is one hell of an inspiring course that demystified the difficult concepts and math behind PCA. Excellent instructors in imparting the these knowledge with easy-to-understand illustrations.

Poor programming assignments, lots of error. Also, the teaching staff has to pull their socks up. No intuition behind anything, only throwing formulas one after the other. I must say if this is the stuff Coursera has to offer then it's not far that other online platforms will take over. No offense but I sincerely request the instructor to improve his teaching skills, as this kind will take him nowhere. It might sound harsh but it's the reality. Nevertheless, I learned something new which will hopefully help in my future, and for that, I will like to thanks the whole teaching staff. I hope you all continue this great initiative, provide quality content, and make learning as easy and affordable as possible. I Will be looking forward to more courses from your side but this time, please come up with new and exciting ways to explain mathematical stuff. Once again Kudos to the teachers and all the students who completed the course!!

This was a very disappointing module compared to the first two modules; I've taken many online courses over the years but this is by far the worst one. The third instructor who leads this module was boring and would work through his examples without explaining how he gets from one step to another. Programming assignments came with very few instructions and would be very difficult for someone with little Python experience (luckily the solutions are out there). The forums are mostly full of months-old posts from people asking for help and getting absolutely no responses from the teachers or moderators. The most active thread was actually just a bunch of people complaining about this course and the instructor. I started a thread because I wanted to know how to solve a problem (I wasn't asking for the answer!) and it was deleted with no explanation.

The first two courses in this series are excellent. However, this third course is taught by a new teacher and this introduces a remarkable drop in quality.
There are of cause different styles of teaching. However, as a minimum a teacher should strive towards conveing to students the importance of the subject at hand and the intuition behind it. However, this teacher settles for monotonously writing out formulas and definitions that can simply be read in the course formula PDF. Thus, watching the videos becomes a waste of time. In turn, this makes it harder to complete quizzes and assignments since one first has to go searching the internet for web pages that actually explain rather than simply state formulas that one needs to combine and apply in order to solve the assignments.

I struggle to understand the thought process behind the course structure in this specialization. The first two courses are very surface level when it comes to the mathematics, which I do not think is a bad thing. However, it seems this last course tries to jam fundamental, and challenging, mathematics into the simplified format of the other two courses. From the comments section, I do not believe I am the only one who thinks this way. Wouldn't it be better to just extend the duration of this last course and make it a challenging, but thorough, introduction to the topics? The former without the latter is just painful.

I found this course to be rather lacking in what it lists as pre-requisites. I found the need to take a course on numpy while I took this course. Also, I'm just confused as to why this is part 3 of the specialization. Why not do a section on probability/stats to prepare for machine learning? I like all the professors, but there's only so much you're going to learn. I found I needed to constantly use the resources, and they are good, but the resources were better than the assignments and instruction, so... I would suggest saving your money.

The intermediate level of this course is accurate, but mainly because of the course's structure. In my opinion this course should not be a part of the specialization as the PCA is already covered in the first two courses. Although this third class is more (and almost only) about the maths I found it confusing in relation with the previous course and their explanation of PCA. Programming assignments are difficult and help the student to think by itself, however they are buggy which may take away the struggling student motivation.

The weakest of the series of 3 in the Mathematics for Machine Learning Specialization. The course videos did not explain the material well enough and referenced significant amount of external reading sources. The videos are full of jargons without taking the time to properly explain them or help the learner develop intuitions. I walked away with a very muddled understanding of PCA even though I was able to complete all quiz and exercises. I recommend a revision to this course so this important topic can be taught better.

Although the topics and lecturer's delivery were nice, but as compared to the two previous courses of the specialization, this one doesn't fare well. The content in the video lessons and that in the notebook were not really planned well in terms of scope. A participant who isn't already familiar with these concepts, would struggle a lot. Only if the reading material, video content and notebook assignments were designed keeping that in mind, it would have been better. Apart from that it was a good course.

Slow notebooks, bad explanations, unclear what to do in the notebooks.
I don't know why i spent so much time to finish the course- maybe because of my perfectionism didn't let me stop trying.
I guess the matter itself is good, but:
1. you probably got to re-record all the videos a little more bit by bit with more examples
2. fix the slow notebooks
3. more assertions for each function instead of for the whole thing in the notebooks
4. more detailed explanations what we are even doing there

If you like traditional lectures, which you go into a math class then feel puzzled, then go for it. Otherwise, the contents of this course are simply going through the mathematics equations and definitions, which can easily be found in textbooks. Ironically, the previous two courses in this specialization used lots of graphics and animations to help you understand the maths (either in terms of equation-wise or intuitively), this course completely lacks this element.

Only on week 1 but this is already a disappointment compared to the first two classes in the Math for ML series which were excellent. Some content is presented too fast. Quiz questions are ambiguous. I already paid for the class so I will finish the content but not worry about passing quizzes and assignments. Had I known it would be like this I wouldn't have paid for it. Check out the other reviews and forum discussions to see what others think.

Pretty bad all around.
The teacher keeps throwing formulas without taking the time to explain why they are useful, and what they represent.
The first two courses were really good, and this one is a bummer.
Most of what I learned was learned elsewhere, the course acted as a detailed syllabus with some practice quiz (of relatively poor quality).
It's still worth taking if you completed the first two courses and want the specialization certification.

Course is inconsiderate to new learners in that new concepts were very sloppily introduced. Like the first two courses of the specialization, this course is shallow, shouldn't be anyone's introduction to the subject and is a refresher at best. Unlike the other two courses, it assumes python knowledge, doesn't explain relevant syntax in the assignments; which made me take a lot of long unnecessary detours to get the python implementation right.

After the other two awesome courses of the specialization this one stays far behind my expectations. Weakest course of the specialization. Instructor is obviously knowledgeable but does not provide much intuition. Programming assignments are really difficult and at many points frustrating. 2 more weeks and therefore comprehensive instructions would be desirable. Couldn't appreciate that course as much as I wanted to.

After having done the first two parts of the specialization, I am afraid this one didn't stand up to the high quality bar the previous two had set. The programming assignments are unnecessarily long and complex and the overall material is not as engaging, connected and concise. I might give it a good rating as a standalone but now I can't avoid comparing it to the other two parts of the specialization.

This course is a great departure from the premise of bringing Mathematics and ML together. The instructor basically throws dozens of calculations, Math for the sake of Math. No intuition is gained, either. The instructor is only preoccupied with writing down the calculations. You either "swallow" all the Algebra or not. I'd suggest the complete reformulation of the videos.

Compared to the first modules in this series, the instructor explains almost none of the intuitions behind the maths and will skip over large essential pieces required to complete assignments and quizzes. It assumes a wide knowledge of programming and broader maths that was handled significantly better in the earlier courses.

The explanation of the course is hard to understand. Some misunderstanding. I have to study on youtube or somewhere to pass this course. The videos in the course are lack information. 2 stars because of the PCA assignment helping 1 plus star for the course. The two courses previous in this specialization are good.

I think there's a big gap between the material in the video and the assignment even though the professor explains great details of the topic, but lack of explanation to strenghten the material he just covered. moreover, the assignments have no clear instruction and sometimes there're some mistakes

This is the least effective course among the three courses in this specialization. The reading materials have no context. People who have not been around those math symbols have no idea what the reading materials mean. They are not intuitive at all. The design of the assignments are poor as well.

This course has been a nightmare. Dense and obscure lectures, "challenging" assignments asking for things that haven't been properly taught in the lectures and often unclear instructions.
Yes, some useful concepts are taught but overall it's rather a waste of time.

Programming assignments seemed to be written from a completely different direction, and instructions are vague and misleading. (The math assignments were not so bad.) There was no staff or mrntor engagement in the forums during the period of the course.

Unlike the prior courses in the series, topics not clearly explained and brought too sudden. Also none of calculations shown completely, instructor just wrote results in the end. Due to all these reason I was not able to finish the course.

The course assignments could be improved dramatically, though the course itself has very good content if you want to have a taste of how linear algebra (predominantly) can be implemented to solve machine learning problems.

First two courses in this series are great but not this one. Lectures and exercises are not related. I do not feel like I have totally understood PCA. Was able to complete the final assignment thanks to the internet.
