Coding Challenge #92: XOR Problem

[ad_1]
In this coding challenge, I “solve” XOR with my simple JavaScript neural network library.

    can someone tell me whats wrong whit this code?

    void setup(){
      
      size(500,500);
    }
    void draw(){

      background(255,0,0);
     
     x = 0; {
    while( x < width)
     x = x +1;
    ellipse(x,250,50,50);
    }
    }

    Hi Dan, let's use Iris dataset.

    Oh, Dan. You don't know how much you brighten up my day after seeing 16:15.

    I don't know anything about neural networks but this was amazing! Keep the videos coming!

    "Imagine how you would build that with a circuit". Umm, do you mean using an XOR gate?

    Is it just me or are some other people getting this error?

    So glad I discovered your channel, I'm on the 2nd semester of computer science and I aspire to be as good as you one day 🙂

    awesome video, i really love you're work and your way to teach! but i don't really understand why would i use a neural network to solve XOR … it's a classy for SVM …. but maybe i'm overfitted 😀 … of cause if you don't know that your data isn't linear separable you can't know that SVM would be the better strategy right?

    Amazing Dan, thank you !!! 🙂

    you give me motivation

    Just realized that your matrix library is way more faster than numpy! Really!

    Awesome work Dan!

    Nice and simple I like it

    Hi! I see this video on about genetic alghoritm in processing https://m.youtube.com/watch?v=iV-hah6xs2A how can I replicate that? How did they do?

    Can i use p5.js library with react-native to make fun games???? Please respond.

    The other thing that may or may not have helped is training it on a fractional input… Especially if you want to control the shape, but I wonder if it would help Keep itfrom getting stuck

    Will you use relu?

    Why are there multiple correct solutions? Does it not really matter what's in the middle so long as the corners are the correct values?

    A 25min coding challenge on my Monday morning commute! Great way to brighten the start of the week.

    Excuse me but are you building a Skynet?

    a quick question, i am new to coding, background in accounting, have some high school experience in Java, and i have just started to learn the types of logic used in programming, how much time do you think it will take me to come at a level where i can understand and follow your projects, also any tips that'll help accelerate my learning, avoiding any common pitfalls will be appreciated. Right now i'm planning to put in 6hrs per week into learning this, will be focusing on Python and R.
