NodeNet

"NodeNet" is a project aims to bulid neural network. It's oriention is to collect plenty of types of neural networks and provide manager to organize and test it, and the neural network libary can work without needs of manager isolatedly. It is a project belongs to NOOXY. There still lots of miles to complete it. Article about it might be established some day. Visit us www.nooxy.tk.

Requirement

  • C++
  • Python
  • Python package: NumPy
  • Python package: Matplotlib
  • Python package: CuPy(Optional)

to install Python packages

#!/bin/bash
sudo python3 -m pip install numpy matplotlib

to use Nvdia GPU (example: ArchLinux)

#!/bin/bash
sudo pacman -S cuda
# Install CUDA
sudo vim /etc/profile
# In vim add /opt/cuda/bin to your path
# finally
sudo python3 -m pip install cupy
# if something wrong try
source /etc/profile
# or
sudo reboot now

Directory

bin

node manager's executable files. They are compiled by C++ side source code in main directory, and it's build target is mainly macos(Darwin) now.

main

Source code file for node manager. There include two type of launguages C++ and python. They are completely seperated(work independently). However, it's functions act similarly.

For C++

there are source for matrix(mathematical lib for ann), ann(artificial neuron network library) and node manager(main program).

For python

We are contructing now. Not yet to be describe. For launching manager

python3 manage.py

If you need Nvidia GPU support(for really large size of neural network) simply change all

import numpy as np

to

import cupy as np

research

Test the nerual network for finding good models etc.

test

A directory to test some functions that not yet to be added to mainline.
