Neural Networks

Introduction

It is 2025 and time for me to spend more effort in understanding AI a bit more. So I will start, hopefully, at the beginning

What are Neural Networks

Watching the YouTube [here], it showed an example network which would be used to identify a digit in a 28 x 28 pixel picture. The video talks about about breaking the pixels up and passing them through layers. The layers determine a value for the thing you are looking for which comprises of a meaurement + weight + bias

For each neuron in one layer the result of the thing you are looking is calculated along with the weight and bias
This can be expressed as
