← IDEAS? What Should We Do Next?

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  8. 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??????

  9. 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.

  15. 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.

  16. 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?

  17. 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?

  18. 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.

  20. 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.
