Open Source Neural Networks?

Sleexy asks: "Does anyone know of any open source neural network / Artificial Intelligence projects for any platform, or anyone doing open source work in this field?"

I have some code

[Rayban]

I have some code I whipped up a few years ago when I was playing with this stuff. I'll have to dig around for it, but if you email me, I can send it your way.

NODE is in pre-devel phase

[Kaufmann]

I'm coming up with a relatively AI-y database system that is intended to store and process information like a mind; it's called the Node-Oriented Database Engine (NODE). It'll be open source, and probably written in Scheme or Common Lisp. If you're interested, email me.

I have

[game]

It was written in C++ 2 years ago has an adaptive network engine and a fuzzy system to adaptive network translator. Documentation is only available in hungarian, but I can give you pointers to the papers which served as a basis for the program.

Drop me a line if you're interested and I'll send the source or provide access to it. On the other hand I have seen many similar things at CMU archive, so you may have luck there.

Some Neural Network Sources

[substrate]

• University of Toronto Neural Network Group has some software which fits the Open Source model.
  
• University of Stuttgart has a neural network simulator. Source is available, its GPL.
  
• Pacific Northwest National Laboratory has a slew of links to free/share ware. No idea if any of it is Open Source.
  
• Karsten Kutza maintains Neural Networks at Your Fingertips.
  

I got all of these off of Google. Try entering 'neural network' as a search term and seeing what hits you get.

I may have some old notes, papers and source code on them in that area of maximized entropy I call my apartment. If I can find anything I'll post them and GPL everything.

Article in LJ #63

[gavinhall]

Posted by Critical Mass:

The Linux Journal has an article on the Stuttgart Neural Network Simulator. Great article! You can get the SNNS at http://www.informatik.uni-stuttgart.de/ipvr/bv/pro jekte/snns/snns.html

AI/ALife Howto

[hypnotik]

There is a *great* Artificial Intelligence / Artificial Life HOWTO here geared towards Linux.

Open AI

[SEWilco]

Well, you asked about AI as well as NN:

ThoughtTreasure understands questions and gives answers. Uses assortment of methods to analyze text, understand problem, apply common sense, and find answer to problem.

CLIPS rule and object expert system tool.

Knowledge Server Toolkit is a Perl-based system for monitoring and acting on continuous information flows, such as alerting when telemetry indicates unusual conditions.

Bayesian Neural Network source code available

[marclee]

If you're interested in feedforward neural networks with Bayesian learning. Radford Neal at the University of Toronto has a lot of nice code that runs on Linux/UNIX. The URL is http://www.cs.utoronto.ca/~radford

Using higher level languages w/ NNs

[-alex-]

You can also check out Octave which may have somethings. This is a language similar to MATLAB. There is a toolbox that will work under MATLAB (and maybe Octave) from the Technical University of Denmark located here. By the structure of MATLAB and Octave, the source code is usually "open" (read: you can look at it) and it is in this case as well.

Xnn/Nn others and more

[LinuxBean]

There is a plethora of open source neural networks out there, I myself wrote one in Scheme. SNNS is good so is Xnn/Nn (also does outputting of neural network c code). There is a FreeProp out there some place i think.

AI/AL

[Lochinvar]

I have just finished a Java implementation of a petri-net model for npc's in a game. It's not open source yet, but I think I can release the model by mid July
lroome@gulf.uvic.ca

jess - The Jave Expert System Shell

[sohp]

I have poked around with jess. It's sort of based on CLIPS, and is programmable in lisp-like syntax. It also has hooks that allow you to extend it in Java or even call Java from within you Jess programs.

Speech Recognition Neural Net

[musique]

Here is a speech recognition toolkit with a neural net at the Oregon Graduate Institute:

http://cslu.cse.ogi.edu/

The license for this project is not exactly "Open Source", but it is free for educational institutions. The neural net takes as input 5 LPC constants and has as output biphones (hundreds of them.) It's written in C. You can download it, play with it, and learn stuff. The license for commercial use requires payment.

I actually tried to make modifications to it in a class, but due to time constraints and lack of documentation I was unable to finish my changes. I think I made an A anyway and I learned a good deal about AI.

Re:MBP -- "best" Backprop NN s/w IMO

[yzorderex]

This is really helpful
unlike the poster above who recommends Google.
I have a list of NN and AI links also. But too many are to long dead college projects last updated in 97 or otherwise inappropriate.
Have gone through the same frustration several times keeping updated in this area and your efforts are appreciated
