SNNS (Stuttgart Neural Network Simulator) is a software simulator for neural
|
|
|
|
networks on Unix workstations developed at the Institute for Parallel and
|
|
|
|
Distributed High Performance Systems (IPVR) at the University of Stuttgart.
|
|
|
|
The goal of the SNNS project is to create an efficient and flexible
|
|
|
|
simulation environment for research on and application of neural nets.
|
|
|
|
|
|
|
|
The SNNS simulator consists of two main components:

|
|
1) simulator kernel written in C

|
|
|
2) graphical user interface under X
|
|
|
|
|
|
|
|
The simulator kernel operates on the internal network data structures of the
|
|
|
|
neural nets and performs all operations of learning and recall. It can also
|
|
|
|
be used without the other parts as a C program embedded in custom
|
|
|
|
applications. It supports arbitrary network topologies and the concept of
|
|
|
|
sites. SNNS can be extended by the user with user defined activation
|
|
|
|
functions, output functions, site functions and learning procedures, which
|
|
|
|
are written as simple C programs and linked to the simulator kernel.
|
|
|
|
|
|
|
|
The graphical user interface XGUI (X Graphical User Interface), built on top
|
|
|
|
of the kernel, gives a 2D and a 3D graphical representation of the neural
|
|
|
|
networks and controls the kernel during the simulation run. In addition, the
|
|
|
|
2D user interface has an integrated network editor which can be used to
|
|
|
|
directly create, manipulate and visualize neural nets in various ways.
