Got an amazing introduction to Graph Analytics in Big Data. Technical issues with Neo4J made this course a little more challenging than necessary. But the introduction to Spark GraphX was invaluable.

This course was excellent as an introduction to Graph Analytics and using Neo4j. Not only did I learn a lot, I've been given tasks related to what I've learned in this course after finishing it.

Week 5 seemed irrelevant

My problem with this course is the same that with the Machine learning course: it is too basic, and the big data aspects were more a demo than a real course. I know about graph theory and networks in general much more than it was covered in this course, and I was disappointed that all the big-data context was limited to the handson sessions of week 5. I have to mention that the theoretical parts (first 3 weeks) were high quality and nice, just did not cover anything new for me.
On the contrary, the graphx handsons were drafty and really lacked explanations of the steps. I suggest to rename this course to something like "Introduction to graph and network analysis with a big-data demo" not to mislead users.

There were a number of software configuration settings for which we were not forewarned, some settings that I saw now way of changing in the community edition of Neo4j, and the queries in week 5 were not adequately explained. Furthermore, some of the earlier lectures appeared to be "modified from the original lecture, cut down to create required material and optional material. The lectures were cut in crude fashion, and the instructor would go from one slide to the next, sometimes starting in mid sentence. This subject can be interesting and useful information, but the content needs to be reworked so that we better understand the software use, and what we are trying to achieve.

My personal opinion but we seem to be just breezing through at a very fast pace the details associated with the applications. We are presenting but not really conveying anything meaningful given the pace that they are covered. Seems more of a distraction than value to the overall objective of the course. It would make more sense just to provide a slower placed recorded session on the tools .. and I do mean slower with explanation. Perhaps and optional course where there could be a deeper drill down into to the apps. It also seems that some of the course material is not up to date with the current versions of the apps as well.

This course continues the style of the specilization. Wrong instructions, theoretical lecture and inconsiderate course structure. Maybe this course includes too much concepts and skills and students may not be able to command all of them within such a short period of time. I have to say it's a waste of time to download all these softwares in the course.

First week of 3 min video. Seriously we want to dive into the subject. And the last two weeks should have more content. Felt like much more copy and paste without understanding why you did that. Understand this should be introduction to Big Data... But the price you pay for the introduction is too expensive.

Full of errors, short of explanations and support, just trying to figure out what to introduce in the command line, not knowing what I am actually doing and why. There are issues reported in the forums eight months ago that have not been fixed. At least one can get a fair idea of what can be done.

Some items are interesting, but the lectures seem goal-less: not enough structure to help understand graph analytics. There's something there but I didn't have much of a takeaway. Introductory material should have more structure.

Most part of materials about Graphs analysis and parallel programming models left unclear despite I have tried to rewatch the lectures some number of times. Previous courses of the spec were clearer

Many tools... very high level approach.
Complex theory is also explained very quickly and disconnected from the hands-on exercises.

At least, in the previous courses, the instructors were explaining good. This course, for the first three weeks, the instructor is rushing, we would require to pause every minute and see it again. Also the Neo4j has removed the exe file for windows and providing only zip since and year. There is not updates of videos related to that on how to run Neo4j using zip files. Not only on this course, all the courses were still with oldest version of applications. I managed with those applications. But with Neo4j, I can't even proceed with the course. Worst course ever I took. Also I see user who has taken course has posted in Discussion Forum regarding this a month ago and there is no reply for the post from the instructor. My advice is not to take this course at any case.

I was unhappy with this. It was clear that this course was pulled together from a superset of other material, and that it was not checked for consistency or completeness. The students were tested on their ability to write down a specific phrase from a video rather than on application of the principles learned from utilization of the graph database tools. (Broccoli -- REALLY???)
Further, the lack of response to questions posted in the forum indicates a lack of engagement from instructors and / or facilitators.

Very interesting topic, but poor course. They totaly kill the oportunity to tech good things.
Tools you need to accomplish are not working all the time and you need to search for the solution in discussion without knowing what are you looking for. I would appreciate whet they give at least some hint what to look for. It could be valuable. Than you just copy paste solution and do not knot what are you doing.
I think deep knowledge what and why are you actually doing will be more valuable than cover every topic.

The material on graph analytics was of introductory level. A string of interesting ideas, with unclear explanations. The lesson on GraphX was basically a copy-paste introduction to it's abilities without actually teaching how to use it. The transcripts are full of mistakes. Someone not proficient in English or hard of hearing would be confused by them. It was somewhat difficult to understand the main lecturer. The best part was the explanation of Neo4j - and it was at an introductory level. A disappointment.

The worst couse I ever take!!
1) week 1-2 is completely useless
2) The whole Neoj4 part is a disaster. You really need to check whether your protocol can still work under the lastest version in windows
3) The GraphX is basically crap. The pipline get stuck from the filtering step as :
[Stage 4:=============================> (1 + 0) / 2]
No FAQ and No debug,
It is irresponsible!!!

This course is supposed to be the most interesting, and most challenged one of this specialization. However i am quite disappointed with the instructor and the contents he put together. He speaks too fast without much clarity, and worst of all, i can tell most of the time he reads from the scripts without really conveying much knowledge about the contents.

Module 4 was absolutely pointless and terrible. The software was not easy to install and crucial instructions were missing. Additionally, the assignments required working with a dataset of size that was beyond the capabilities of most personal computers.

The last week had exercises run on a Linux VM and, different from the other courses, there were no instructions on installing Virtual Box and the Cloudera VM. I had to get the instructions at the forum, but they should be at the first week readings.

Sorry but didnt see the point to this course as part of the overall specialization. Maybe as part of the "Load" in a ETL workflow but there would have been other options, better options. Felt it was just thrown in.

Terrible. Did not understand most of the course. Badly explained. Manuals to software were not working. Shame, because it is a nice subject.
