    Rotating an image recursively. One of my favorite algorithms!

    Posted: 25 Sep 2020 08:09 PM PDT

    I made some UX/performance improvements and added additional algorithms to my traveling salesman problem visualizer based on feedback I received here. This is a browser-based educational resource for learning common algorithms.

    Good sources to learn algorithmic decomposition vs object oriented decomposition.

    Posted: 26 Sep 2020 01:14 AM PDT

    Request-: Say I create a program for calculation (+ - * /). And I create separate functions for all of them, then I guess it is called algorithmic decomposition.

    But, how will OOD look here?

    Comp architecture a necessity?

    Posted: 26 Sep 2020 03:40 AM PDT

    Hello I am currently going for my comp sci Degree and was curious about one class that I have that I don't find completely interesting. The class is computer architecture with my comp sci degree I plan on pursuing a software focused career is it extremely important or even relevant to have hardware knowledge while mainly focusing on software. I may be wrong but I believe I saw a post explaining that it's not needed but could be helpful with expanding your opportunities.

    I'm just reaching out to see what the great minds r/compsci opinions are.

    Thanks in advance.

    Edit: I lied it's not that I don't find it interesting it's that it is very difficult to follow and be invested in with how terribly my text book explains everything.

    The First Appearance of a Real Computer in a Comic Book

    What is a simple problem that is yet to be solved where the solution will require you to develop a software system, hardware system, an algorithm or an ML algorithm?

    Posted: 26 Sep 2020 01:43 AM PDT

    This is for a class project, I would appreciate any suggestions.

    Data Science vs Data Visualization

    Posted: 25 Sep 2020 11:09 PM PDT

    I know that data science mean, take some data and understand the flow and structure of data by analyzing it and perform some market strategy, and Data visualization is the process of taking raw data and transforming it into the graphs, charts and image, or even into videos to gain more and more information from that.

    but what is the main difference between them? I m totally confused. :(

    3D A* with JumpPointSearch

    Posted: 25 Sep 2020 04:46 PM PDT

    I want to extend my current A* implementation with JPS for better performance in 3D Grid wtihout weights.

    Was wondering if it would make more sense to for example use a high level A* searching in clusters and then limiting the search space based of the granular A* based on that. Instead of using JPS, idk if its even possible/feasible to use A* with JPS inside a 3D space without weights.

    Can anyone help me out and give some input, would really appreciate it!

    How could I solve a Rubik’s cube using a variation of local search?

    Posted: 25 Sep 2020 04:21 PM PDT

    I've managed to create a rubiks cube program thanks to codetrain and codebullet - I've also got a working solver using the human algorithm. Now I'd like to implement local search or SAT constraint solver... just unsure where I'd begin.

    Book question has me really confused: What functions does the Assembler provide (list and explain each)? I thought it only converted assembly into machine language.

    Posted: 25 Sep 2020 05:56 PM PDT

    The wording implies that there are multiple functions of the assembler, but I thought its whole job is to translate assembly language into the hardware's machine language. Am I wrong?

    Mastering CSS can also save design time. You don't need to spend as much time in image/graphics programs if you learn how to manipulate images in CSS. You can apply filters to images, clip them, apply masks, and more just with standard CSS.

    [R] Facebook AI Wav2Vec 2.0: Automatic Speech Recognition From 10 Minute Sample

    Posted: 25 Sep 2020 11:38 AM PDT

    Current speech recognition systems require thousands of hours of transcribed speech to reach acceptable performance. However, a lack of transcribed audio data for the less widely spoken of the world's 7,000 languages and dialects makes it difficult to train robust speech recognition systems in this area. To help ASR development for such low-resource languages and dialects, Facebook AI researchers have open-sourced the new wav2vec 2.0 algorithm for self-supervised language learning.

    Here is a quick read: Facebook AI Wav2Vec 2.0: Automatic Speech Recognition From 10 Minute Sample

    The paper Wav2vec 2.0: A Framework for Self-Supervised Learning of Speech Representations is on arXiv.

    Search Pattern Algorithm in a binary list

    Posted: 25 Sep 2020 09:45 AM PDT

    I was wondering if there already exists Search Pattern Algorithms for binary sets.

     ls1 = [0,0,0,0,1,1,0,0,0,0,0,1,1,1,1,0,0] ls2 = [0,1,0,1,0,1,0,1,0,1,0,1] ls3 = [0,0,1,0,1,0,1,0,1,0,0,1,0,1,1,1,0] 

    like this where in ls1 there are chunks, in ls2 there are no chunks and in ls3 is somewhere in between.

    All i want to do is analyze this lists behavior, how do you handle this kinds of sets?

    Or if you know some articles, books, videos or something like that, that might help me it will be appreciated.
