  2. Some issues...

    1 - There is something wrong with the user's session management, when browsing pages the account name on top-right always change to "login register" links;
    2 - The "claim you offer" button is not working, there is an error in its loading;
    3 - The link to open the account options (top-right) is kind of small, I always click on the name thinking that is going to open a menu and the page is redirected to the Dashboard;

  3. Pronunciation of 'Data'

    Hi, this could be a feedback but please bear in mind it may be very opinionated. I checked with several colleagues and none of them are comfortable with the pronunciation of the word 'data'. For me it is a very distracting part of the videos and I decided to turn off the audio due to that...

    I did of course look it up and the pronunciation can be:
    1. 'Big day-tah'
    2. 'Big dad-ah'

    Both are correct. The second one is however very uncommon and can be experienced as very distracting (in my opinion). I am writing this feedback to…

  6. Continuous Video Playback

    It is quite annoying that I have to open links after links to play short video clips (1-5 mins) for each topic. Any way to play the videos continuously like other e-learning platform

  7. IOS app

    This is a great library for learning Data Science / Big Data.

    And the availability of the iOS app for learning will be really helpful to some of us working professionals, who want to make this change towards Data Analytics.

  8. Should allow to login using username

    I think, it'd be easier to maintain & use the account with multiple options available. it's good that you provide multiple email options, but it'd be great if your provide to login using username. What is the use of a unique username if it can't be used instead of your email id for login? I changed my email id & was unable to login after that as your database didn't receive my other id. So, that made me lose all my progress with the previous account. Thank you!

  15. update the link in DS0105EN>Mod 1> Creating an account page

    In DS0105EN>Mod 1> Creating an account, it asks us to go to datascientistworkbench.com and create an account. But if you try to do it, it redirects to the Cognitive class page. I spend a while going in circles-frustrated that I was following the steps in the video and yet not getting to the virtual Lab page...It was only when I got to the lab page that I saw that the link is now https://labs.cognitiveclass.ai/.... It might help putting a note in the "create an account" video page saying that the new link is https://labs.cognitiveclass.ai/.. This would make it…

  16. The review question in the Demo section is incorrect

    The review question posed in the Demo section is actually one of the answers. The question can be inferred from the other answers but needs to be corrected.

  19. Highlight items that you are clicking on in the videos.

    I just watched my first video and I just wanted make a suggestion (as I am a video developer also) to be more clear as to where you are clicking with your mouse. In this case it was the menu on the left hand side, but windows were popping up and I had no idea why. You can perhaps add cursor effects or callouts to draw viewers attention. thanks.
