dysii 1.4.0

A C++ library provides a collection of classes useful for machine learning applications.
dysii is a C++ library provides a collection of classes useful for machine learning applications.

Features are added to the library as needed, so that it does lack some completeness. What is included, however, is well documented and tested, and may be considered fairly sound for research purposes.

The library has been optimized for performance, while maintaining a modularity and generality that makes it suitable for a wide range of applications. Along with general code profiling and benchmarking, considerations have included:

- selection of efficient algorithms,
- use of efficient low-level matrix operations,
- conversion of calculations to matrix form where possible to facilitate this, and
- use of memory-efficient sparse matrices where appropriate.

Main features:

  • The Kalman filter and smoother.
  • The Rauch-Tung-Striebel (RTS) smoother.
  • The unscented Kalman filter and smoother, and the unscented transformation.
  • A particle filter and smoother, including a parallel implementation using MPI.
  • A Runge-Kutta numerical solver for ordinary differential equations.
  • Probability distributions and stochastic processes, such as the Gaussian distribution and Wiener process.
