What is Billnet?
Billnet is a modular neural network simulator platform. Its primary goal is to simulate as many as possible of the existing architectures and algorithms for neural networks in an effective and light weight manner so Billnet could be used simultaneously for research, educational and industrial solutions.
Where can I find Billnet?
Billnet is now hosted in savannah. You can download the latest CVS version from there. Older versions are currently not available.
Why to use Billnet?
Due to its modular nature we find Billnet very good for algorithm developing. Once the core platform remains the same it is very easy to compare different algorithms under the same conditions, and reliably decide which is better suited for the specified task. Billnet is also good for students who may want to take a closer look at the neural network technology or maybe implement an algorithm for training purposes. Billnet is small and fast, thus very effective for real world applications. It can be easily be part of an embedded or real time system. Finally Billnet has a proven track reckord.
