neural-net

This repository implements a neural network using 2d arrays and math in pure java. No other frameworks and libraries used.

You've come to the right place if :

• you're new to ML
• fed up with those heavily abstracted libraries like scikit learn, tensorflow, numpy (yes i'll consider numpy as abstracted!)
• want to understand how these math formulas are translated to code
• aaaand want to see it all in java (cause why not)

There are a series of medium blogs which take you through the implementation.

1. Defines the goals and the base object - Matrix
2. Explains how feedforward is implemented
3. Explains backpropogation
4. Tests the implementation on the MNIST dataset
