Good course to give a basic understanding of predictive modelling and analytics. Good assignments and opportunity to review peer submissions help reinforce the learnings.
this course teach you about the technical of using tools for predictive modeling. very useful for you who want to learn the fundamental of analytics.

This is an important class in data science general and very important in the Data Science curriculum. The class was covering very important concepts and eventually was able to deliver.
However, There were two major issues in this class in particular. One, the instructor’s English was very hard to follow, even with Closed Capturing that sometimes could not convert. As someone that English is not his first language, I can empathize, however there should have been better editing to the videos.
Two, the XLMiner Software we had to use in this class was only available for 15 days trial. This is a 4 week class and by week 3, the trial has expired. I did not plan to buy a license, and they will not extend it by a couple of weeks ( I tried calling both Coursera and Solver.com). And even though any other free tool (Python, R, MS Studios, etc) could have been used they gave different results and was not good for this class. This was frustrating. I ended up signing up for another 15 day trial with another account but that should have never been an issue.

Compared to the first course I felt this one was hard to follow. Information came at a furious pace with little explanation. It reminded me of a business algebra class I took once that had a stand in teacher. The stand in usually taught theoretical match and ended up talking over all of the student's heads. We had to bring him back down to earth. Also the XLMiner tool is only good for two weeks. I verified this with the help desk for the tool. You need better directions and/or a better tool that can be used throughout the 4 week course. Even your translator had issues with some of the annunciations by the instructor. Due to that you need better visuals, explanations of concepts and how he comes around to some of the answers he gets. I really hope the other courses are more like the first and less like this one or I will drop this specialization and go for another. Also I will no longer consider CU Boulder for my Masters.

The professor is clearly an expert on the topic, but I don't believe this was an effective learning experience for me. Several reasons for this: (1) The professor was extremely difficult to understand, and this is exacerbated when trying to learn some more complex topics that involve equations and visualization. (2) Most of the lectures seemed to be rushed. For me, it seemed like we jumped from an introduction of the topic to expert level concepts without much transition or explanation.
Overall, I found that I didn't learn much in this course. I simply did the best I could to pass the quizzes and complete the assignments. This would have been fine for me 20 years ago, but these days I am taking courses to learn and better myself. I do not feel like this course helped me.

Not satisfied with the course structure. As you progress in the course, the course seems to be rushed with little detailing. For example the concept of calculating Gini Index. The calculations were not explained and the students are expected to figure it out basis the formula shared in the earlier slide. Had a hard time figuring out the calculation when a problem around Gini index calculation appeared in the Assignment. The accent of the instructor is also hard to understand. Had to refer to transcripts many a times to understand what was been said.

Really good content but the lecturer speaks really fast like reading script ,unnaturally and not communicative but I understand what he speaks, even if the subtitle sometimes goes wrong, however. Peer-Graded system is not productive. I found someone has copied my final assignment, at least should have reviewed my assignment back but did not, really shameless and uneducated. XL Miner on the cloud, for Mac, is free for 31 days with student license, however its interface and process is really time-consuming, perhaps lots of users.

I found the instructor did a very poor job of explaining the concepts he was trying to get across. He read the material as fast as he could and it was obvious. Also, it requires software that has a 2 week license unless you want to pay for it (and this is a 4 week class) or can find ways around it by having multiple email addresses and other ways to trick their system. I don't recommend this course if there are any other options.
Very Poor experience, the instructor was very bad, could not understand anything which he said , this can be seen by the number of [INAUDIBLE] present in the subtitles text. The number of application assignments and the questions were very good , with practice I understood all the concepts and I really think that was very helpful.If the instructor is changed and course content increased , this would be a very good course
All around a pretty horrible course. I am not sure who is giving it 4 or 5 stars. Yes the instructor is knowledgeable but he is not a teacher. Additionally he speaks very fast with an accent which makes it difficult to follow along. I would have preferred we spent more time learning about regressions and less time learning how to use an odd Excel Addon that you have to pay for.

I've been struggling horribly with this course. Quite difficult knowledge presented with too little explanation. Much more visual graphs, summaries are needed to explain these data while in the course it is mostly a speech. If pictures are presented, they are without proper description. Whats more the course focus on showing how to do the models, but not how to interpret them.

I really think the lecturer has so much knowledge and wisdom to share with us. But it all goes in vain when students can't understand properly what the lecturer says because of his accent.
I tried very much to understand, it was very hard for me, even with the transcript.
I hope to learn more.

Very difficult to understand, even with CC. The backbone of this course is a little bit of macro handy work from 1995. I am not the most experienced in the field, but i find it hard to believe that any F500 company would use let alone pay for use of that thing.

I would suggest this course to update its video by using text to speech. "The Data Scientist’s Toolbox" is a good example !
too many errors in the scripts, I have posted some on the course forum. some assignments questions not mentioned in the course.

This course requires advanced pre-existing knowledge of statistics to really be of any use. New concepts, formulas and techniques are barely explained but are presented as a 'given'. The course does give you good working knowledge of the Solver tool.

Interesting course however, it was very difficult to understand the instructor. I've had to use the lesson subtitles and slide pack to study the material; then just used to play video lesson to be able to open the next lesson.

Its really hard to understand the instructor even subtitles mentions inaudible on many places. There should either proper presentations available or Coursera can redraw this course with another instructor

i didn't understand the lecturer very well due to his course explanation way, adding to this i had so many problems with the included Xlminer license which forced me to Buy it on my own budget.

The instructor rushed through the videos, explanations were not very clear. The material was not very in depth and the coursework was not that helpful in understanding the concepts.

The instructor speak to fast and it's hard to understand what he said too many times. The material in the course in not well done. I believe that the course needs to be remake.
автор: Catalina S•
It assumes course takers have knowledge on statistics and probabilistic. Explains too fast, and at the end is not clear the use of each technique

Much below my expectation or the level and quality the other courses bring. There are so many areas within this course that could be improved.

The accent of instructor is too strong to understand, it's an unpleasant experience to have listen through the class.

its very difficult to understand the accent of the person otherwise content is very useful

Could not understand the instructor and the information was not useful
