simple-ann

A barebones, simple-as-possible neural network module in Python.

This Project

There are 3 code files in this project:

• src/net.py, which contains the neural network code
• test/train_net.py, which is a simple script to test the neural network
• main.py, which runs the above test

Sample output:

Potential Improvements

There are a lot of libraries that have far more features implemented, and this module does not attempt to emulate them. However, some things that would be nice:

• Variable number of hidden layers
• Different training algorithms
• More error-catching
