    This is KarateClub a Python library for unsupervised machine learning on graph-structured data. It was built on top of NetworkX, has a Scikit-Learn like API, and installed by pip. The selected techniques include node embedding (e.g. DeepWalk, GraphWave, Grarep, BANE), graph embedding (e.g. Graph2Vec) and graph clustering (e.g. Label Propagation, Ego-Splitting, BigClam). In the future, I am going to keep it updated and add new algorithms.

    How relevant are groups, rings, and fields to computer science?

    Posted: 12 Jan 2020 06:04 AM PST

    At first I thought these were topics relevant only to pure math, but there's one thing that stands out: since linear algebra can operate over any field (e.g. real numbers or complex numbers), and linear algebra is hugely relevant to both theoretical and applied computer science, maybe representing a problem by choosing an appropriate field makes the problem much easier? Does this happen anywhere in computer science?

    And are there any other parts of compsci that rely on algebraic structures?

    Making a website

    Posted: 13 Jan 2020 04:28 AM PST

    Hi! You guys mind suggesting some ideas? We are supposed to make a website for our applied software engineering course... It should make good use of OOP concepts and some basic AI/ML (if possible)

    .apk to .rar/.zip error

    Posted: 13 Jan 2020 03:31 AM PST

    I don't know if this is the right sub-Reddit but here it goes

    I'm trying to convert an apk file to zip or rar using cmd, after that I want to use the unrar tool to open it but I found that cmd only changed the extension (not how it should be done "I mean change the signature and other stuff that makes a rar a rar"), so I get the 'this file is not archive' error.

    how to properly convert it (using cmd)? keep in mind that after I convert it I only get the error inside the cmd, but when clicking on the rar/zip file itself it opens with no issues.

    Projects that went closed source?

    Posted: 12 Jan 2020 04:10 PM PST

    What are some projects that had an open source license and moved to a closed source license?

    This is for a research article, so if you can share why they went close source and your opinions that would be great :)

    [Edit] thank you everyone for your responses!

    Is this plagiarism? I'm new to computer science and I'm not too sure.

    Posted: 12 Jan 2020 04:38 PM PST

    So essentially I needed to make a project and java, and so I looked around since it's definitely been done before, and there were some Youtube tutorials etc. One of them had some good class ideas (in terms of dividing them up into different objects) so I essentially copied that skeleton. I didn't go any further and none of the actual code was copied. I feel like it is plagiarism but I can't think of a way to divide up the objects any further.

    it was chess and the one I looked at had like,

    Piece class and a class for all the actual pieces that were a child of Piece. square. Board. Game. start menu. and an object for a checkmate. main method to run the game.

    Mine was the exact same except I don't have a class for a checkmate.

    How to make a password without knowing it, but being able to retrieve it later (only in desperate measures)

    Posted: 12 Jan 2020 04:54 PM PST

    So, as the title states, I'm looking to generate a password that I can't know and that I can later retrieve in desperate measures. I was thinking of creating a random password, RSA encrypting it with 2 random 10 digit primes, and then storing the encrypted passcode while deleting the unencrypted passcode as well as decryption key and the 2 randomly generated prime numbers as those were only needed to find the totient of their product. Then if I needed to, I could retrieve the password by iteratively testing random 10 digit primes to see if the totients matched up, meaning i could generate the original decryption key. Are there any better solutions to this problem? Thanks in advance

    Any past/present graduate students who specialized in Machine Learning/Computer Vision?

    Posted: 12 Jan 2020 09:31 AM PST

    I would really appreciate it if you have a look at my Statement of Purpose (SoP) for an MS program and give your feedback on it. If you're willing, just leave a comment. I'll DM you!
