← 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.

  1. Update Lab 1 Values

    Re: BD0211EN - Lab 1
    Currently the path to the working directory is written as
    /resources/jupyter/labs/BD0211EN
    the correct path is
    /resources/jupyterlab/labs/BD0211EN

    Also, the ReadMe.md file I extracted contains 98 lines and thus readme.count() returns 98. The notebook says it should be 103.

  2. 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?

  3. Wordpress Plugin

    I suggest you create a Wordpress plugin like DataCamp-Light plugin
    https://github.com/datacamp/datacamp-light

    or like DataQuest-Caravan plugin
    https://github.com/dataquestio/caravan_wordpress

    This idea will help an unlimited number of course creator and blogger around the world because it will make things easier
    I suggest this idea because people need to learn but not all people are developers or programmers and people need something smart an easy

  4. 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?

  5. 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.

  6. 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.

  9. 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.

  10. Include a platform program that transparently handles calculations with numbers with uncertainties

    Hi! I`m chemist!

    Can you include this package to Jupyter Notebook, Python?
    https://pythonhosted.org/uncertainties/index.html

    To calculate uncertainties in measurements, in chemistry we use symbolic algebra packages such as Matlab or Maple.

    However, I would like our students to be able to migrate to the cloud

  17. I believe the anser to the following question is wrong.

    Retrieve the elements stored at index 1,2, and 3 of 'a_list'

    I suggest the answer should be:

    A[1:4]

    ['hello', [1, 2, 3], True]

    The suggested answer int he docs is "a_list[1:3]" which only returns two elements.

  19. 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.
