  1. Workbench resources display

    I don't find a clear access to the resources I'm using (no. cluster nodes, workers, amount of free storage, etc.)

    ... and it would be great if I could have the possibility for requesting more resources (for example making more clear how could it be scaled up to Bluemix)

  2. 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!

  3. Small typo

    There is a small typo in this notebook: "#### Let's fixes these problems." instead of "#### Let's fix these problems."

  4. 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.

  5. 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"

    So, please update current version of Seahorse.

    Thanks for your efforts in putting together such a wonderful environment.

  7. Correct question 1

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

  8. 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.

    In the lab the statment:

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

    How is this conclusion made?

  10. 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.

  11. 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?

  12. 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.

  15. Not always so clear on when I have a correct answer

    Your user interface doesn't always make it clear that I am correct. Also adding print(xxxxx) to the answer when you're asking for output shouldn't be counted as wrong.

  16. I suggest you require prerequisites before allowing anybody to enroll in this program

    Taking the data science classes by anybody unfamiliar with any of the basic programs used during this course makes no sense. It's monumentally frustrating trying to figure out the basics like this:
    Exercise 3: (Jupyter notebook)
    2. From the menu, click on "Insert", then "Insert Cell Above" or "Insert Cell Below".; While it's clear how to insure one or the cells, it's difficult to figure out how to enter the second now.
    3. Note you can use the keyboard shortcuts: [a] - Insert a Cell Above; [b] - Insert a Cell Below. Really? What am I suppose to click on??????

  20. Remove error in function r2_score

    r2_score first argument is the true value and the second one is the predicted value, so the code should be corrected.
    Thanks
