science/libsvm-3.21 (Score: 0.006224396)
Library for Support Vector Machines
This slave port adds Python interface to LIBSVM.
science/libquantum-1.1.1 (Score: 0.006224396)
C library for quantum computing and quantum simulation
libquantum is a C library for the simulation of quantum mechanics, with a special focus laid to quantum computing. It started as a pure quantum computer simulator, but support for general quantum simulation has been recently added.
science/libsvm-3.21 (Score: 0.006224396)
Library for Support Vector Machines
LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM). It supports multi-class classification. Since version 2.8, it implements an SMO-type algorithm proposed in this paper: R.-E. Fan, P.-H. Chen, and C.-J. Lin. Working set selection using second order information for training SVM. Journal of Machine Learning Research 6, 1889-1918, 2005. You can also find a pseudo code there. Our goal is to help users from other fields to easily use SVM as a tool. LIBSVM provides a simple interface where users can easily link it with their own programs. Main features of LIBSVM include * Different SVM formulations * Efficient multi-class classification * Cross validation for model selection * Probability estimates * Weighted SVM for unbalanced data * Both C++ and Java sources * GUI demonstrating SVM classification and regression * Python, R (also Splus), MATLAB, Perl, Ruby, Weka, Common LISP and LabVIEW interfaces. C# .NET code is available. It's also included in some learning environments: YALE and PCP. * Automatic model selection which can generate contour of cross valiation accuracy.
science/mbdyn-1.4.3 (Score: 0.006224396)
MultiBody Dynamics analysis system
* What MBDyn is o a command-line, direct initial-value problem solver with a large, flexible multifield element library o a research tool o a community developed, research driven open-source software * What MBDyn is not o a complete out-of-the-box ``bells and whistles'' GUI for solid modeling o a commercial tool o a completely supported software
science/metaf2xml-2.0 (Score: 0.006224396)
Parse and Decode METAR, TAF, SYNOP, BUOY and AMDAR and Write as XML
metaf2xml can download, parse and decode aviation routine weather reports (METAR, SPECI, SAO), aerodrome forecasts (TAF), synoptic observations (SYNOP), observations from buoys (BUOY) and meteorological reports from aircrafts (AMDAR). Data can also be taken from decoded BUFR messages. The extracted data can be written as XML or passed to a user-defined function (all done in Perl). It also provides XSLT style sheets to convert the XML to plain language (text, HTML), or XML with different schemas. A web-based (CGI) user interface can be used to download and display up-to-date weather data from NOAA, Ogimet, and other sources.
science/minc-2.2.00 (Score: 0.006224396)
Medical Imaging NetCDF
MINC (Medical Imaging NetCDF) is a medical imaging data format and an associated set of tools and libraries.
science/mol2ps-0.4b (Score: 0.006224396)
Read molecular structure files and generate Postscript output
mol2ps is a freely available command-line utility program which reads molecular structure files in different formats and generates Postscript output for 2D display. The Postscript file can then be used e.g. for creating a bitmap file, using a Postscript interpreter like Ghostscript.

Massively Parallel Quantum Computing library and program
science/mpqc-2.3.1 (Score: 0.006224396)
Massively Parallel Quantum Computing library and program
MPQC is the Massively Parallel Quantum Chemistry Program. It computes properties of atoms and molecules from first principles using the time independent Schrodinger equation. It runs on a wide range of architectures ranging from individual workstations to symmetric multiprocessors to massively parallel computers. Its design is object oriented, using C++. Capabilities o Closed shell and general restricted open shell Hartree-Fock energies and gradients o Second order open shell perturbation theory (OPT2[2]) and Z-averaged perturbation theory (ZAPT2) energies. o Second order closed shell Moller-Plesset perturbation theory energies and gradients. o Robust internal coordinate geometry optimizer that efficiently optimizes molecules with many degrees of freedom. You can also validate your mpqc binaries when you employ other settings by: % make validate >& validate.log & (it may take few days, though) For details, please see file:///usr/local/share/doc/mpqc/hierarchy.html or http://www.mpqc.org/mpqc-html/mpqcval.html
science/paje-1.97 (Score: 0.006224396)
Generic visualization tool for GNUstep (Gantt chart and more)
Paje is a graphical tool that displays traces produced during the execution of multithreaded programs. Other programs can also generate traces for this tool. Key Features * Supports multi threaded programs - each thread of the analysed program can be individually displayed, or multiple threads can be combined, to reduce screen space usage. * Interactivity - each entity represented on the screen can be interrogated for more information, - related entities are highlighted as mouse cursor passes over some representation LICENSE: LGPL2 or later
