A new (mostly error corrected) version of samt_fuzzy hase been released. Additionally this versions allows the installation in a central directory
(like /usr/local/SAMT_FUZZY) and the data in an separate directory under your home. This allows the multiple use of samt_fuzzy in a server environment.
Please adapt your .bashrc according to the "INSTALL.txt"

The new version 3.2 of SAMT is out. SAMT will be distributed only as source code and must be compiled on a Linux system (Debian 6.0, or Ubuntu 10.04 LTS are preferred). Older version, like the CD version, USB stick version or virtual box file version are obsolete. The file structure is still the same so your maps can be further used.
Additionally the SADATO comes in an error corrected version.

The first version of the Fuzzy Generator as part of the SAMT_Fuzzy development tool is out.


17.may 2010
The final version of SAMT 3.0 is out.
It runs in the virtual box as a virtual machine with zero installation under all common operationsystems like Linux, Mac-OS and Windows.


11.may 2010

The new version of SAMT 3.0 is out. This is a pre-release for the new version SAMT 3.0.
It is implemented as a virtual machine based on SUN: VirtualBox. This simplifies the usage of SAMT dramatically.

SAMT Data Tool (SADATO)
is an integrated development platform for neural networks (NN) and Support Vector Machines (SVM). It also combines a data base engine (sqlite3) with the statistical library apophenia. This allows the efficient storage of data sets and the statistical analysis of the data. All is wrapped by a graphical user interface written in QT and developed under the operating system Linux.

The new usb-stick based version of SAMT can be used directly from the stick without the need of installing additional software. All components are included. That means the compiled code of SAMT and toolboxes, the source code, same example maps and the development software like gcc and all the libraries. This allows an easy use of SAMT and provides a basis for an installation on the hard disk.
The installation on an usb-stick is not difficult for a Linux user. It based on an installation of a knoppix system on a stick and adds two files: the knoppix_data.img contains all the additionally installed software and the samt.tgz which contains the SAMT sources and binaries. After installing knoppix on the stick and adding the knoppix_data.img the stick has to be rebooted and the SAMT can be unpacked to the Linux (second) partitionon the stick. Please follow the hints or send me a email if there are some difficulties.

Kind regards

Error Correction Version 2.8.5
  • new kadane implementation with more than one maximum subarray
  • error correction in grid.cpp (memory leak)

02.April 2008

The final version 2.8 of SAMT/DESIRE is ready for download. This version is an error corrected version and contains a new tutorial
  • error correction
  • new wavelet functions (MSLA) i
  • ntegrated filter algorithm (based on Fourier)
  • new tutorial
  • in NNQT the regularization was improved

25.January 2008

The final version 2.6 of SAMT/DESIRE is ready for download.
This version was cleaned, some old code was removed. For example the complex model was not to have proved one's worth and the dynamic simulator for compiled models was removed.
Many new things were included.
The best is the muparser, a grid-calculator that is fast and easy to use. For the statistical analysis the static packet R is part of the CD-version on SAMT. This opens great possibilities to combine spatial simulation with statistical analysis.
Again many thanks to all the testers. Here are some highlights:
  • very fast grid calculator based on muparser
  • new maximum subarray algorithm kadane (named after the inventor of the linear subarray algorithm)
  • approved project management (models are linked to projects)
  • approved documentation
  • simplified menu structure
  • some error correction (for example in the flood fill algorithm) some batch programs for neural networks and support vector machines as test, will be replaced by a graphical user interface controlled toolbox in one of the next version of samt


25. May 2007
The new version (2.4) of SAMT is ready an can be downloaded
The highlights are:
  • new data type: complex model
  • <new menu structure/LI>
  • SVD as filtering function
  • new fractal decomposition algorithm
  • new filter algorithm using a Gaussian kernel with fft
  • new cluster algorithm based on hill climbing
  • some neural network tools as stand alone tools
  • error correction in SAMT
  • enhanced documentation

13. October 2006
The new version (2.2) of SAMT is ready.
The highlights are:
  • new spatial interpolation method based on counter prop network
  • counter prop as simple neural network
  • enhanced rbf function including speed up of kohonen feature map
  • test version for watershed algorithm
  • error correction in splatter and SAMTDESIRE
  • compatibility test for the new qwt5.

28.May.2006
SAMT was ported to qt4.1.x This port and a lot of new features and improvements legitimate the version jump to 2.0
Here are some highlights: new 2D view and improved control behavior; improved neural network (parameter plot, improved algorithm); training of fuzzy models; SAMTDESIRE can handle fuzzy models or neural networks from SAMT; better documentation and tutorial.
SAMT is available as iso image to burn a self booting knoppix CD or as source package to compile.
SAMT was splitted into a source + binary part (located on usr/local) and a working part located on your home directory.
Please adapt the .bashrc to work with this new structure.
13. February 2006:
Samtdesire was ported to the new version of QT (qt4.1). This library is free for Linux and windows so it was possible to build a free version for windows.
Samtdesire needs additionally the new version of qwt.
01.December 2005:
Fast, Easy Interactive Modeling and Simulation of Dynamic Systems, Neural Networks, and Fuzzy Logic DESIRE as separate system is available.
We have decided to offer DESIRE as a separate open source program. It can be used without installing SAMT.
For some users this opens a way to use DESIRE without all libraries that are necessary for SAMT. The only additional library (except qt, that should be installed on your Linux system) is the qwt-library. This library can be found in the Internet or on the download section.
To install DESIRE please download it and unpack it:

tar -zxvf samtdesire.tgz

Then goto in the new directory samtdesire/src and call qmake. Qmake generates a Makefile.
After make the new generated samtdesire is located in the directory samtdesire.
Remark: please install qt and then qwt before you install DESIRE.
26. September 2005:
The final version 1.0 of SAMT/DESIRE is ready for download. This version contains a lot of new possibilities including a new dynamic simulation toolbox. I hope that the software is almost usable (not too much errors). SAMT was tested in projects in the ZALF and together with other user (many thanks to all).
Here are some highlights:
  • DESIRE as dynamic simulation toolbox is now part of SAMT (many thanks to Prof. G.A. Korn)
  • The directory structure was changed to use SAMT in a network environment
  • An new project management system was introduced (A project combines data and models)
  • new documentation
  • little changes in menu structure
  • some error correction

13.May 2005:
Version 0.8 ready for download
  • sensitive analyses
  • fuzzy sensitive (change rules)
  • new 3D-library
  • new splatter
  • new elevation
  • edit and create point themes
  • variance analyses (experimental)
