Erudite is an application for training and testing back propogation neural networks using the ANNeML (Artifical Neural Network Markup Language) XML format. It supports testing and training neural nets with CSV files and has support for randomized training sets, optional adapting learning rate, sigmoid or hyperbolic tangent transfer functions, optional bias and weight adjustment locking, and more.
Salad (short for Letter Salad) is an efficient and flexible implementation of the well-known anomaly detection method Anagram by Wang et al. (RAID 2006). Salad is based on n-gram models, that is, data is represented as all of its substrings of length n. During training these n-grams are stored in a Bloom filter. This enables the detector to represent a large number of n-grams in little memory and still being able to efficiently access the data. Salad extends Anagram by allowing various n-gram types, a 2-class version of the detector for classification, and various model analysis modes.
h5tools provides third-party tools for working with data where the underlying storage object is HDF5. The toolkit currently has two utilities in it: The HDF5 NeXus writer API is a set of functions which allows writing data in the NeXus data format, using only HDF5 function calls. H5merge will merge any two HDF5 or NetCDF4 files.
The rt-stepper project provides a USB CNC controller solution. Most CNC controllers are designed to be driven with a PC parallel port. The rt-stepper solution replaces the parallel port with USB. Users can convert their existing parallel port CNC controller into a USB CNC controller. Designers can integrate the hardware into there own CNC controller. The PC side software is based on the popular EMC2 software at www.linuxcnc.org. EMC2 provides 4-axis support, a complete gcode interpreter, a trajectory planner, a GUI front-end, backplotting, and more. The best part of the solution is since the rt-stepper hardware provides the real time step pulses, you can now run EMC2 on Linux, Mac OS, and Windows.
Z88 is a fast, powerful, and compact finite elements analysis program. Z88 features 20 finite element types; it covers plane stress, plate bending, axial symmetric structures, and spacial structures up to 20-node Serendipity hexahedrons. It comes with a user-friendly interface (the Z88 Commander), and has a powerful mesh generator. It features a DXF coverter and two plot programs. The FEA solver is included, featuring an in-situ Cholesky solver along with the Jennings storage method. COSMOS and NASTRAN files from Pro/ENGINEER can be imported. Z88 is a project of the University of Bayreuth, Germany.
TooN is a very efficient numerics library for C++. The main focus of the library is efficient and safe handling of large numbers of small vector matrices and providing as much compile time checking as is possible. The library also works with large vectors and matrices and integrates easily with existing code. In addition to elementary vector and matrix operations, the library also providers linear solvers, matrix decompositions, optimization, and wrappers around LAPACK.
Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. The API is deliberately similar to Matlab's. Integer, floating point, and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS numerics libraries. A delayed evaluation approach, based on template meta-programming, is used (during compile time) to combine several operations into one and reduce or eliminate the need for temporaries.
