  3. Comments related to big data

    I would like to commend the great presentation. Even though it focuses on data sciences, it looks like it covers more on the traditional approaches. It would be great if it also covers some big data related area such as in-motion data; not static data sets. Thanks.

  4. Navigation, Error and Product Version

    Navigation in the Final Exam/Info page needs improvements. when we are in information page there is no link option for Return to Exam home page except the link in the header.

    After finishing the quiz, at 0 minutes remaining clicking on the answer shows an error but it that's not the user friendly way.

    In videos, the product version and size of the data studio and db2 are older version and small size, but when attending the question which depends on version is a problem, also newer versions are large in size. So incorrect information makes downloading problem.

  5. Some images are not loading in the blog posts

    I see that some of the images are not loading on these blog posts consistently. The videos on Saeed's post load consistently, though.

    Is there something wrong with the images being hosted on www.bigdatauniversity.com?

    Hi,

    Ref: Deep Learning Fundamentals (ML0115EN)
