This is Part 2 of A Neural Network in Python, which was a very simple neural network to learn the XOR function. This part builds on that example to demonstrate more activation functions, learning a simple math function, adding a bias, improvements to the initial random weights, stochastic gradient descent, mean square error loss function,…
In this article, I’ll show you a toy example to learn the XOR logical function. My objective is to make it as easy as possible for you to to see how the basic ideas work, and to provide a basis from which you can experiment further. In real applications, you would not write these programs from scratch…
This is a fun little program to generate ‘computer music’, specifically ‘bytebeats’ which sound like the chip music featured in the early computer games. As is well-known, sound can be digitised and stored in computers. Conversely, numbers can be converted to sound. But those numbers don’t have to come from a file, they can be generated on the…
