I'm extremely excited with what I have learnt so far. As a newbie in Machine Learning, the exposure gained will serve as the much needed foundation to delve into its application to real life problems.

The course was highly informative and very well presented. It was very easier to follow. Many complicated concepts were clearly explained. It improved my confidence with respect to programming skills.

Very frustrating - students are required to use IBM proprietary products which are inconsistent in their results and even running - the exact same code will run in one notebook but not another. The instructions for the final test are incredibly unclear in what is expected. Their sample code they give to grade the final test DOES NOT run. IF you can finally get it to run it doesn't produce the same results as they require to pass the test. The peer grading is awful - I got both a 0 and a 100 which netted a 50 (fail) twice. The zero was even though I had all requirements met (which even if the results were wrong should have yielded partial credit) and the student gave no feedback yet there is no way to ask for a new grader. I've done several courses via this certificate. 1 - the IBM Watson studio requirement needs to go. It's awful in every way and has turned me off to using Python. How can I use a product in my job that every time I run the same code it gives me different results or just won't run? 2 - the peer grading needs a way to have a request to have it re-reviewed by someone else (I resubmitted with a full summary of my results at the bottom and the same person gave me a zero again). I only stuck through and finished the course because it is required to get the certificate.

I'm finishing this certificate program because it would be easier than starting another one from scratch. I've been disappointed with most of the courses and this is no exception. There are mistakes, typos, and poor grammar throughout the course. They have a system to report mistakes, but I should be getting paid to fix your course - not paying to fix it, right? The quizzes are an unnecessary waste of time (they ask very minute, arbitrary questions about videos that are just meant to give you a brief overview).
The labs are the most / only useful aspect of the course because that's where you learn actual code - but they don't explain HOW the code WORKS. They just say what the code does and then they show it to you. There's a difference, as any good teacher knows. This course was clearly created by data scientists, not teachers (and certainly not masters of the English language). I would recommend this certificate program if you already know python and data science and you are just trying to earn a badge that will look good on your resume.

For me this has been very disappointing, I really wanted to give this course and all the other courses in the IBM Data Science catalog a chance.
However I have not been able to get the answers I need to continue to learn from this course, the only way to get any real answers to questions that one might have is to make a post on the course forum and responses can take a very long time sometimes 3 days or more and considering the thousands of posted questions on the forum many can often go unanswered!
The only other way to really find answers is to do an online search, which I have found gives very generic answers to very specific issues, neither alternative has been helpful!
To give credit to the course, it may not be an issue with the course itself but rather the platform.
Either way I am still left disappointed and stuck and don't think I can continue to learn so long as my problems go unresolved!

The course is very shallow. It never goes in depth with the algorythms, neither in a mathematical sense, nor in how they are implemented and best used. They don't even cover hyper-parameter optimization using cross-validationThis is not ok for a final course in the IDM Data Science Certificate, especially because Regression was already much better covered in the Data Analysis with Python Course. Moreoever, the Final Assignment features an unbalanced dataset, for which the course does not prepare students enough. If one tries to copy the methods used during the course without reasearching much about this on their own, they will train models that would be unacceptable in a real-world scenario. Worse still, the "model" answer provided does exactly that.

I learned a lot, but the final assignment is just a mess - on so many levels. My biggest takeway is that even well-rated courses with qualified instructors end up causing material issues. The quality of the final project implies that people will be trained here to create ML models that will have real world consequences and will not be properly understood or validated. And that's without looking at the huge number of typos, bad programming techniques, and more. Had to give up on the final project due to those difficulties after spending 10 hours of my very early mornings without any reasonable progress.

As am going along in this IBM certification, the quality of courses is getting depleted. This course has by far the worst standard in terms of quality of content and assignments. The worst part is that they encourage you to use IBM cloud services which are the worst and require improvement themselves. But the worst part was the peer guided assignment. With no clear instructions, peers that have no idea checking your assignments and long delay for waiting the grade for it, god help you! Don't waste money on this course. Hopefully, coursera takes actions against IBM if they don't update this course.

I am really disappointed, the course is basically a really introductory course aimed for someone who doesn't know any math or programming. Not a single comment on the maths, or the algorithms of Machine Learning, only a really superficial description of the existing algorithms (a description of what are they for, nothing about how they really work).
And Python is just an anecdotic theme, only examples of notebooks on how to do a specific thing (most of the times without explaining much) and the final project is simply copy and paste the notebooks together.

I felt like I learned the least amount from this course when I was hoping to learn the most from it. The final assignment was extremely bad. The instructions were very confusing (it said to find the best k for all even though that only applies to KNN). In addition it was littered with typos and incomplete sentences adding to the confusion. If I hadn’t spent so much time and money on the courses prior to this one I would of quit based on the lack of quality in this course.

Maybe Good for some people but this course was proper useless for me, you must know python to take it otherwise you will struggle , because it doesn't show you any coding. its based on theory you watch videos that are 100% focused on mathematics...... at the end there is a peers graded assignments where other students grade your work and that can be a headache. i was abou to give two stars but because it gave me a headache from the start it deserves one star.

Like others, I need a solution for the localhost error in the final project other than "download and install other tools." I cannot change the configuration of the machine I am using. I cannot be alone in this as many employers, and public systems do not allow users to install products,
Is there something wrong with my code or is it (as I suspect) in the lab environment? Please take this issue seriously and fix the issues,

Only one advice. Do not purchase this course. Instead of teaching data science, the course is designed to promote IBM cloud platform. There is minimal exercise questions. Complete course is designed in a random, unstructured manner. The explanations provided are not adequate enough. This course is a complete waste of time, money and energy.
Please stay away from these IBM promotion videos(Professional Data Science Course)

It has been locked for me telling that I have to wait until 22 July ( 7 weeks !!) until I can continue . What the hack !! I had to pause for a month but it was clearly stated that one can proceed after a pause at any time. No possibility to get the deadlines reset is given either and on top of it the the help center is not reachable by email so that I could resolve the issue. Very, very frustrating !!!

This course was more advertising IBM products and at the end to do the final project asks to make an account in IBM. The procedure for building account is not updated with the current IBM website. Trying to make a IBM cloud account, I needed to enter billing information eventhough it was a free service...
I think IBM should try to improve their website before teaching others how to use it

Finished the course, now have to wait 6 weeks to receive a certificate anyway.
This course makes you use their awful third party application, which was a massive pain to setup due to errors on the IBM website.
The content is lackluster and barely talks about the important details of the algorithms used. The coding portions are essentially copy-paste and you feel like you learn nothing.

The capstone project in wk6 has too much technical problem in NS Labs. Same code that work perfectly in IBM cloud does not work in NS Labs due to compatibility problem. I cannot finish the capstone project in IBM cloud because I have used up all me free hours in IBM cloud. However, the provide notebook has too much problem in NS Labs. Very disappointed!

The course final to use multiple methods to predict loan payoff. No matter what model used, predicting 100% loan payout was more accurate. If the point of the project was to "show how you can't machine learning everything", I would say it succeeded there, but not a very good way to kick start a better understanding of ML applications.

I hated that all the instruction was all math and none of it python. The instructor was completely uninspiring. You really should have instructors with some level of charisma. The course was littered with technical errors. This is the worst MOOC I've ever taken. It is a crime that people actually have to pay for this.

Absolute waste of time. Content is outdated, and clearly not properly maintained. Final projects are based on data that is littered with errors, to include errors in the code written by IBM as an example to the student. I literally can't submit the final project because of an error in the instructors code.

Simply the second worst course I took on coursera (the first on is the upcoming one in this porf certificate course, where the guy records the videos in his car with his potato cellphone).
No clear explanation, one bored instructor shows ppt pages with little to no explanation of math equations.

very poor quality. limited information and explanation. The staff makes us feel like they are not confident enough to answer questions. The only reason for going on is that I already invested a lot of money and time. definitely not recommended. It should be improved.
