    Modern day Metaprogramming?

    Posted: 28 Mar 2018 08:11 PM PDT

    I've a recent interest in "Metaprogramming" tasks such as code generation/replacement and Domain Specific Languages.

    • Are there any recent advances/research in this area? Maybe I am missing the recent lingo or something: it seems everything I find is from the 70's!
    • Have you used anything like this in your work?
    • Where can I learn more about this? Is there a "goto" textbook?

    Thanks!

    [Algorithm Question] Given a sorted list of values, find any number of values that add up to a target

    Posted: 28 Mar 2018 08:43 PM PDT

    I was recently asked a question like this. The best answer I could come up with was to take each item and add the items that follow until I either run out of values, or until my running count went over the target. If my running count went over the target, I repeated the process but starting 1 index forward in the list. If I analyzed this correctly, I think this has a O(n!). Are there better algorithms that I can be using instead?

    [Finite Automata] Help building a context free grammar where one element is a subset of the other?

    Posted: 28 Mar 2018 04:56 PM PDT

    The question

    build a CFG for {xR #y : x,y in {0,1}* and x is a substring of y}

    Thought process

    I understand that xR y where x = y is:

    S -> 0S0 | 1S1| null

    I'm having a tougher time with the substring portion. RIght now I have:

    S -> 0S0 | 1S1 | A | null

    A -> 1A | 0A | null

    THis essentially says that y ends in x, but I don't know how to append onto the S rule to add {0,1}* to the end without it ending up in the middle ( IE 0S0A could lead to 0A0A)

    Can I get pointed in the right direction?

    How to do a great review article on automated negotiator agents ?

    Posted: 28 Mar 2018 02:43 PM PDT

    Hi ! I'm doing my first review article. wanted to know if you had tips or time to peer-review what I tried to achieve. Thank you for your help in advance ! I have to sum-up and comment on 4 pages on an article asking When Will Negotiation Agents Be Able to Represent Us. I'm not new to multiple-agent systems but rather new in automated negotiator.

    The only things I had to respect but the template were :

    • to do a summary of the article (in particular I should highlight the answers to the following questions: why the problem is interesting and important, what are the contributions and why are they important, what is the place of this article in the literature? )
    • a personal critique of the article. In this review, I have to try to find the positives and negatives of the article (for example, did I understand the evidence, do they have enough detail, what would you have liked? find more in the article that is not there, what you found good in the article and who is there, etc ...) and to try to suggest ways to extend the work of the authors.

    As far as it was my first attempt I followed the wikihow guide to summarize a journal article I know I should have rather used the How to Write an Article Review ...

    Here is my attempt. You can clone it with git with the following link : https://git.overleaf.com/15169278xzdfgnjvfmrb

    I have to give it back to my teacher before Friday

    Thank you very much for you help !

    I Would Love Your Feedback

    Hi all!

    I recently developed a K-nearest neighbors algorithm that outperforms the Scikit-Learn K-NN algorithm in terms of both classification speed and accuracy on the MNIST data set (repo linked below). I am not in college yet, and I don't have anyone to talk to about this kind of stuff, and I am wondering if this small project is perhaps something I could use as a piece in my portfolio when applying for jobs/research positions in CS/ML areas?

    Thanks! https://github.com/samgrassi01/Cosine-Similarity-Classifier
