  2. Courses on natural language processing

    Hello,
    Everything on cognitive class has really proven to be the best of all courses to me. I have a small suggestion, most of the courses are related to data science but there is not much on natural language processing. I request you to add some courses related to the subject.
    Thank you

    The Website was down/not accessible last night, when I am in the final exam of PY0101EN, please help me to reset my final exam result.
    Then I need to attend the final exam again and win the badge.
    The current result only shows that only 20% result was submitted and recorded.

  6. Retake Exams

    The point of this site is to learn and I find it ridiculous that you cannot retake a course if you fail it. That does not encourage users to learn it only teaches that you should get it right the first time or quit. I now understand what I did wrong and would like the chance to prove so and receive the badge.

  8. Correct the link to docker-entrypoint.sh for Mongo 3.4

    There's a link the the docker-entrypoint.sh script for the Mongo 3.4 docker container. Or rather that's what's supposed to be linked. The link is actually point to the script of Mongo 3.0, which is not on Github.

    Broken Link:
    https://github.com/docker-library/mongo/blob/master/3.0/docker-entrypoint.sh

    Correct Link:
    https://github.com/docker-library/mongo/blob/master/3.4/docker-entrypoint.sh

  9. Hadoop 101 course

    The course has good content, but the instructor is just reading the lines instead of trying to explain them meaningfully. It definitely needs improvement. Please look into it.

    Thanks.

  10. This service is simply Awesome.

    Although its in initial state but I love visiting this site for learning new technologies. What point I really like of this platform is:

    1.I can see my course details from mobile.
    2.They are self paced, need not worry for timelines (I am an Accenture employee, don't have much time :P)
    3.Hands on Lab

    Suggestion: While opening site from mobile as of now its very difficult, so tried downloading Android app, but its not getting me logged in using gmail.

    However I am happy to learn new things and get a badge to show what I have learnt.

    Kudos to…

  11. ST0101EN exam error

    There's a question in the ST0101EN exam, "If the standard deviation of a variable is larger than the mean, the variable depicts:" The correct answer given is "high variance," but this is not the case. In the general case, there is no meaning to the relationship between the standard deviation and the mean (in the specific case of count data, there may be meaning...)

  12. review the answers with the students to the final exams after submission

    Dear Whom-ever-is-responsible

    While I passed the map-reduce/YARN course, it would be really useful to get feedback on the answers I got wrong on the final. I understand that if there are a limited amount of potential questions, you don't want a free copy of all answer floating around the net. Unfortunately, at the moment I am unsure if I got a question incorrect because of actually not knowing the proper answer, or due to lack of clarity in the question (which was apparent for several)/misinterpretation.

    Just FYI

  13. Please improve presentation of Hadoop 101

    Pronunciation in Hadoop 101 course is not clear at all. It is very difficult to understand what the presenter is saying. Also the speed is too fast. The presenter is just reading out text. The presenter should understand that the initial level of course is taken by those who don't know anything about Hadoop. The course material and presentation should have been designed keeping this in mind.

  14. fix Scala kernel

    The Scala kernel isn't working, making it difficult to get some hands on experience on labs that use the Scala kernel, eg. all of the Spark labs.

    Thank you

  15. Relability of Website

    I encourage lot of people to go for this site and learn, trusting upon the reliability. I found them complaining regularly about the lack of reliability of the website, mostly slow or down, as from past 2 days not able to login to https://courses.cognitiveclass.ai/login. It affects the trust and user engagement. On top of that even after a day of not working,we have not found a single notification saying what is happening. Please build a monitoring system and assign a responsible person to make sure the website functions professionally, even in down time.

  17. BC0201EN - Most of the Quiz questions aren't from Video presentation

    This course doesnt not have a transcript. Lectures videos are good but a powerpoint PPT or the transcripts would definitely help to refer back. Mostly Quiz questions does not come from video presentations

    For example, genesis block was not discussed int the Module 3. But there is a questions on this in Quiz.
