学生对 加州大学圣地亚哥分校 提供的 大数据导论 的评价和反馈

Very interesting course. Explained concepts I'd heard of but didn't really know about. It is a foundation course for a specialization, it's not enough by itself but very good as a foundation course.

I think the course could be shorten by half. The instructors extended the course into 3 weeks, but I think the real meat can fit into just 2 weeks. They use too many examples and several similar case studies to make the same points about why big data is important and beneficial -- repeatedly.

I know why it is important, that's why I took the course! Just give a few mins intro and move on already.

They even have a session discussing why should learn basic tools and theory and have a quiz about that; A quiz about why should you learn how to add and subtract before using a calculator. They can just explain once and people would understand.

Anyhow, I feel like I learned quite a lot, but those I can do my reading just first chapter of big data book or watch 1-2 YouTube tutorials.

Should not waste so many hours watching the course.

The course provided almost no value , and there was almost nothing covered that you couldn't find online for free. The presentation was probably the worst part of the course: It was extremely boring and made it hard to get through the videos.

I didn't expect much practical parts in the course, but there was even less than what I expected: What was described as setting up a hadoop cluster consisted of downloading a preconfigured VM image and running it, and then typing in a couple of commands that were provided to you. Again, nothing of value was added, and quickly going over the FAQ page of any of the products mentioned would be more helpful, faster and a lot more interesting.

Good intro that also helped me understand some of my previous assumptions

This is a great introduction for Big Data. It helps me to revisit what I learned from the meetups and webinars, then put the fundamental knowledge and information in a solid foundation. Thank you.

Perfect for starters!

I have participated in better courses on Coursera. I think the power point presentations are very very ugly. The colors really don't match well. This could be a lot more visually appealing. Also, for self learners, a bit more text would be cool, even though I know that not having too much text, but rather pictures, is beneficial. The presenter could speak a bit more natural. At the moment, it is very obvious that she reads text aloud. Also, there need to be some more FAQs in the practical parts, because there can be quite a few problems when trying to run mapreduce. I was only able to do it using Google, because I also had to install another hadoop version (5.12.) because my Intel Chipset was not compatible with the version you wanted me to download. There, the file path to map reduce was different from the example you proviided. To be honest, I did not check the Discussion Forums because I was not aware there were any. Maybe I could have gotten help there.

The general concepts of big data (week 1 and week 2) seemed a bit drawn out, much of the same was repeated over and over again. This was not necessary. The peer-graded assignment needs more detailed instructions - like mentioning that it is ok to resize the fields, and that shapes need to be copy/pasted as much as needed.

The intro part is too long. You will not start with the practice till the end of next week and I find that the lectures and videos by then are a lot less complete even when the content is harder. I would have prefer is the theoretical part was shorter and there was more support when we start learning about hadoop

This was absolutely useless. Lots of definitions with no motivation. The one saving grace is that the slides are comprehensive.

This is an excellent course! The teachers are wonderful and the course design is very good! Highly recommended if you are new to Big Data!

course is well designed and structured.

The introduction content of Big Data is very good.

Very good course!

good

Great to get a general Idea on what Big Data means and what are the general uses of it.

this was a great short course for starters in big data analytics and hadoop. the teachers had an excellent in depth knowledge of their field and they communicated it a very learner and professional manner.

Everything was explained in brief manner with day to day examples . Thanks to Ilkay Altintas and Amarnath Gupta for their clear cut explanations and also my reviewers for my assignments . Such an awesome course for beginners. Ample amount of time was given to finish this course successfully

A must to start with course for beginners

the course is very good, thanks for your effort

Having just finished my first course on big data feels really great !

It was awsome.

This is a great course. The best part I liked about this course is connection to the real world scenarios. This helped in identifying the idea of big data. Thanks to the course organizers

Very good course with excellent lecture videos by the tutors.

Very good introduction course! Well rounded and well explained
