GNU Gneural Network


Gneural Network is the GNU package which implements a programmable neural network. The current version, 0.9.1, has the following features:

The network can now learn tasks defined by the user. An example of script defining a simple network which fits a curve is given. We plan to deliver more advanced features very soon. In particular, we are already spending efforts to implement recurrent networks. We also plan to implement learning reinforcement techniques and apply Gneural Network for deep learning applications. We will release the data along with the trained network.

The Ethical Motivations

Nowadays, companies such as Google and IBM are doing a great service to all of us by showing what can be achieved by using Artificial Intelligence (AI). For instance, the results achieved by AlphaGo and Watson are outstanding and truly inspiring (the least one can say). But the fact that only companies and labs have access to this technology can represent a threat. First of all, we cannot know how money driven companies are going to use this novel technology. Second, this monopoly slows down technology adoption. As a matter of fact, data and trained neural networks are rarely shared, and one should always remember that in practice without the training data it is almost impossible to duplicate results (even when the source code is available).

We should ask ourselves: Do we really want that only a few can use AI? Should not Progress and Knowledge be for everyone instead?

In spite of the plenty of AI codes available and released under some permissive license, it is time for a Free AI which gives complete freedom to the users and the community. Hopefully, this could reduce the duplication of efforts one observes today.

This is why the author, Jean Michel Sellier, decided to create Gneural Network and release it under a free license like GPL.
