    Rank these universities for CS Undergrad

    Posted: 28 Jan 2021 03:59 AM PST

    UT Austin Georgia Tech UF UW Madison Purdue FSU UMiami

    Trying to figure out my options for undergrad, only heard back from Purdue so far. I was accepted but for actuarial science so if I did go I'd have to try my luck CODOing into CS, which isn't guaranteed. Since most other schools don't admit by major, this is my current backup option, but I'd like to know which CS undergrad programs are the best out of my other schools, so I'd appreciate a ranking.

    Sources on ASCII

    Posted: 28 Jan 2021 03:38 AM PST

    I'm wondering, if anyone knows of any good sources on ASCII, that I can use for my paper I need to make for school.

    Thanks.

    I SUCK AT DISCRETE MATH AND DONT KNOW WHAT TO DO

    Posted: 27 Jan 2021 11:26 PM PST

    So I took discrete math a year ago and due to me not paying attention and covid starting I didn't really learn much. I still got a b in the class though. Now I'm taking comp sci theory(which is just discrete math 2) and I don't think I'm gonna do well.

    I'm also taking a math department class which happens to be very similar to discrete math and I'm adamant on paying attention and understanding the concepts.

    Option 1: stick it out and see what happens

    Option 2: drop comp sci theory, do really well in my lower level discrete math class and take comp sci theory next semester. This would force me to lose track with my estimated graduation date unless I make one of my future semester a lot harder

    Any insight would be appreciated.

    How to know whether minimal cut problem has overlapping subproblems or optimal substructure?

    Posted: 27 Jan 2021 10:15 PM PST

    https://ibb.co/M8JJ0Dj

    Steps to solve a DP

    1. Identify if it is a DP problem(Overlapping subproblems or Optimal Substructure)
    2. Decide a state expression with least parameters
    3. Formulate state relationship(find a relation between previous states to reach the current state.)
    4. Do tabulation (or add memoization

    [N] ZeRO-Offload: Training Multi-Billion Parameter Models on a Single GPU

    Posted: 27 Jan 2021 03:18 PM PST

    Researchers from University of California, Merced and Microsoft have introduced ZeRO-Offload, a novel heterogeneous DL training technology that enables training of multi-billion parameter models on a single GPU without any model refactoring.

    Here is a quick read: ZeRO-Offload: Training Multi-Billion Parameter Models on a Single GPU

    The paper ZeRO-Offload: Democratizing Billion-Scale Model Training is on arXiv.

    Ideas for a final year project in Computer Science

    Posted: 27 Jan 2021 05:43 PM PST

    Hi,

    I am in my last year in Computer Science and I still haven't decided on a project and I am running out of time.( I should have started working on it months ago ) I have been thinking about researching different Privacy Preserving Machine Learning methods and implementing them, and then comparing them. Another idea I had was to make a COVID-19 app simillar to the NHS one.( local area alerts, venue checks-in, contact tracing ) I think that the app is a better idea as I was told that this type of project ( software development ) tends to get graded higher than the other one. (experimental research) I really don't know what to do. Would be great to hear someone else's opinions/suggestions

    About Comp sci transition,a question.

    Posted: 27 Jan 2021 09:08 PM PST

    Hi!I'm econ major who plans to transition to CS next year.I'm good at math but I have no backround in Physics.Is is possible for me to learn physics from the start in like 5-6 months and struggle less during University?Sorry if the question is vague.I just wanna know if it's actually possible.

    How come the graph of the execution times of a linear max sum subarray algorithm looks like a check mark instead of a line?

    Posted: 27 Jan 2021 11:56 AM PST

    The graph

    The code

    This is weird. Why does it look like this?

    The tests done weren't a ton, but it was this sort of structure: tested different input sizes (8000, 16000, 32000, 64000, 128000, 256000), did 20 tests for each input size, measured the execution time, averaged them for each input size, and plotted them.

    I would have expected, you know, a line for a linear algorithm, not what looks like a check mark. But I don't know what causes this

    Mobile client to Web socket server architecture. Will this work? any comments for production.

    Stuck in Boot pls Help

    Help understanding the math behind the execution time of an algorithm??

    Posted: 27 Jan 2021 09:55 AM PST

    Idk why my brain can't figure this out. But say you have an O(n2) algorithm. You've done some tests and can see the following average execution times for different values of n

    n=10 n=100 n=1,000 n=10,000
    0.0035ms 0.137ms 0.65ms 22.26ms

    I can't understand the math behind trying to use this data to predict the average execution time for when n is, say, 100,000.

    How do I do this?

    Where (online preferred) can I get the best value (or best price) to suffice CS course prerequisite at On-Campus Top CS Master's Admission?

    Posted: 27 Jan 2021 09:25 AM PST

    Hello everyone,

    I am an international student. I have an undergraduate in biotechnology. I plan to apply for the top 20 CS master's programs. First, I need to do the prerequisites because many of the top 20 universities RECOMMEND taking CS courses (Michigan and USC REQUIRE some CS courses though). I have compiled the list of courses that I need to take, such as DS&A, intro to CS, computer organization, Discrete Math, etc.

    Where do you recommend taking these courses?

    From post-bac/non-degree information I can find, people recommend OSU, but I notice that people who are going this route has the intention to switch career instead of going for on-campus master's degree

    From r/OMSCS , I found people are going to community college (Foothill, Oakton, etc.) or Extension school (Harvard, UC Berkleey, UCSD, etc.)

    Please advise and thank you very much for your attention :)

    (If you know that there is a more appropriate subreddit where I can post this question, please let me know)

    Best podcast/video resource for computer systems?

    Posted: 27 Jan 2021 07:45 AM PST

    I am new to computer science and I really need a good resource that I can listen to during the day that will help me to get a better understanding of computer systems (CPU systems, I/O, OS structure etc.) Something that can break down concepts into really simple steps that will help me to better follow more complicated stuff in class! If you know of any please let me know :)
