  2. I want to be able to "Auto Update" and also have "Update Notifications" on my preferences

    There are 2 scenarios:
    1) I don't want to wait for updating every time that an update is available. So, it would be nice to have an option for "Auto Update". So, my DSWB get updated automatically once there is a new update, so I don't have to click on "Update Workbench" every time.

    2) I don't want my DSWB to get updated automatically. I also want to skip the update message that is shown when I open my DSWB. But, I need an "Update Notification" somewhere to show me that there is an update available, so I can click…

  3. Equivalent of screen command in bash

    Maybe there is a way to do that and I didn't find it but an option that allows the user to detach and re attach to a running script would be welcome.
    I would love to be able to disconnect while a long script is running during he night and access it agin in the morning.

  4. Service status page

    Whenever there is an outage, there should be a status page that provides users with the status and estimated up time.

  6. I sould be able to access the cognitive class files from seahorse

    I just doing the Data Science Hands-On lab and it is not possible to the give data sample with is provided in the videos.
    Because the download over http does not work or the server does not allow the download.

    I was wondering why can I not just upload a own file to cognitive and us this file directly inside seahorse?

    I did something wrong or is the an enhancement?

  7. Question for the instructor

    My "ML0101EN-Reg-Polynomial-Regression-Co2-py-v1" exercise equation is:
    yy = clf3.intercept[0]+ clf3.coef[0][1]XX+ clf3.coef_[0][2]np.power(XX, 2)+ clf3.coef_[0][3]*np.power(XX, 3)

    The instructor's is:
    yy = clf3.intercept[0]+ clf3.coef[0][1]XX + clf3.coef_[0][2]np.power(XX, 2) + clf3.coef_[0][2]*np.power(XX, 3)

    Note especially "clf3.coef_[0][2]*np.power(XX, 3)" is this correct?

  8. Question for the instructor

    PloynomialFeature() function in Scikit-learn library, generates a new feature matrix consisting of all polynomial combinations of the features with degree less than or equal to the specified degree.

    Can you elaborate a little more on how the function works?

    N.B. I believe the spelling for the function is misspelled.

    Thank you.

  9. Free GPU

    Floydhub.com is giving GPU free for 100 hours and free 10 GB storage. I am training models easily here. But there are no tools like jupyter lab, bash terminal and jupyter notebook in floydhub. In floydhub, I can download the data direclty into workspace.

    In the lab the statment:

    "It looks like feature sets for multiple linear regression analysis, right?"

    How is this conclusion made?

  11. Elaborate on the Lab statement "parameters are the intercept [...] of hyperplane".

    How is this known? I think the example of Theta T and X differ from the lab.

  12. Correct question 1

    Question one asks for "engine-size" for independent variable but solutions use "highway-mpg" as independent variable.

  14. Correction in Lab-String operations

    In the lab of string operations the explanation of upper method in string operations "this method converts lower case characters to upper case characters" should be present instead of "this method converts upper case characters to lower case characters"

  15. availability of other video format asides HD

    there should be an option for selecting our prefferred video quality of the videos in the module.
    The only option that exists right now is HD, and for some course participants like me, watching in HD format may incur heavy data fees.

  17. topic wise videos..

    the thing is that the courses are good but you should group them acc to a particular topic... for example if need to study hadoop .. make all topics come under it in a particular manner so that we can study from easy to hard level.

  18. Cheat Sheet Tool

    Hello. I guess that would be nice to have a Cheat Sheet Tool embedded in the Data Scientist Workbench. One example of an online tool that I use is https://www.cheatography.com. There are many Cheat Sheet available, but it's always good to be able to create your own Cheat Sheet with things you believe is relevant for your study/research.

    Currently there are two ways to upload notebooks in BDU Labs:

    1. Open My Data in the sidebar. Use the “Upload Data” feature. There is a known limitation of only being able to upload within /resources/data, but Jupyter will still recognize any ipynb you upload as a notebook.

    2. Alternately, open Jupyter. After it opens, drag and drop your notebook from a file window (e.g Windows Explorer or Mac Finder) into your browser. It will upload the notebook and flash messages at the top of the screen while doing so.

    I appreciate that these options can be a little obscure. We’re always reviewing ways to make the user experience in BDU Labs simpler and more intuitive.

  20. Better UX

    The header#global-navigation could be hidden when scrolled down.
    The notebook column could be also larger and its header could also be hidden.

    The UX is really terrible in the current situation. Less than 40% of the screen is used to really display the notebook content. Please, think about changing!
