Project Neural Network #2
Difficulty: medium
Time: 1-2h
Languages: The one you picked
===========================
Program a single perceptron that can take a quantity of inputs (n) and has a single output.
Use the sigmoid function you programmed earlier to squash the outputs/inputs.

Project Neural Network #3
Difficulty: medium
Time: 2-3h
Languages: The one you picked
=======================
Use the perceptrons of the last Challenge and arrange them into layers.
The first layer is the input layer, the next layers are hidden layers and the last one is the output layer.
Every Perceptron gets as input the SUM of all the outputs of the last layer, each multiplied by some value (called "weights"). In later challenges, we will learn how to improve those weights in order to make out Neural Network be a more and more accurate mathematical model.

Project Neural Network #4
Difficulty: hard
Time: 7h
Languages: the one you picked
========================
With this basic Neural Network structure, improve the weights of each single perceptron. For this, use backpropagation. Intuitively it means: "how much does the error value change, when I change this weight?".

π What are your thoughts on pricy hardware (eg. apple)?
π€ Apple is meant for pros, if average users buy it and say it is overpriced is not its fault
π€ Apple is just best. Its for people with less free time like business or coders
π€ I don't have money and i'm sad... and nothing works...
π€ Apple is a luxury brand and people buy it as a status symbol of their whealth, just like expensive watches and jewlery
π€ It is overpriced for its quality, and works very well thanks to marketing
π€ It mostly gives you bad hardware, for high end prices where you would expect your device to atleast be properly serviced
π€ Apple is useless. Can't think of anything better done on their hardware then a same/lower price alternative.
π€ What's it use.. While a less priced hardware may serve the same purpose
π€ I am using the 15nmbp to answer the question
π€ Those are some sort of good but still depends on user
π€ Good if u have money but in general mostly useless
π€ I never used it but i can tell whoever i know has apple is using it worse or its useless itself
π€ For privacy Apple is best
π€ Nice
π€ Good
