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.

All the complexity of the course is concentrated to the last week.

Only 3 stars because the course is in need of a serious update. Neo4J has changed quite a bit since the course was created. Also, there needs to be better instructions for getting the Cloudera VM to work.

I would have liked to put 5 stars. This topic is so important and relevant to big data. After week 4 hands on part, it became obvious we will not see how to implement or interpret the more abstract graph concepts presented in week 3. That was very disappointing.
Moreover, the structure of the course is not as good as the other module. I don't understand the lack of balance between theory and hands on (Not enough hands on to reflect the theory) part.
On a constructive note, I would replace some of the theoretical concepts of week 3 with additional information on how to link a graph database to machine learning OR I would add more hands on exercise to help using those more complex concepts and learn how to interpret them.

I like the content at a high level, and I have a better appreciation for the value of graph analytics. That being said, I struggled with the GraphX hands on exersizes, where many of the Scala commands simply hung.

The course theory was illustrated and demonstrated very well. Examples were shown and the lectures were short but concise. I appreciated this greatly. The professor also spoke very slowly and deliberately, so the viewers could understand and have time to let the information sink in. In contrast, although the guest lecturer for Neo4j was great, the material was not up-to-date and caused several issues in completing the assignment. Other students were able to lead the class in the right direction in order to even start the assignment. The GraphX on Cloudera virtual machine was almost impossible to replicate as well due to the material being so outdated. Week 5 of the course peaked my interest but lacked the resources to completely follow the instructions and understand the material that was being presented.

The last week was absolutely not fruitful at all, with no such introduction given to Scala. That took away all the sheen from the course.

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.

by far the most difficult and poor explained.

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.

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.

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.

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

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.

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

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.

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.

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.

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.
