Description:

The SSA Toolbox is an efficient, platform-independent, standalone implementation of the Stationary Subspace Analysis algorithm with a friendly graphical user interface, a command-line interface, and a bridge to Matlab.

Stationary Subspace Analysis (SSA) is a general purpose algorithm for the explorative analysis of non-stationary data, i.e. data whose statistical properties change over time. SSA helps to detect, characterize and visualize temporal changes in complex high-dimensional data sets.

Changes to previous version:
  • Added example data and Matlab script for generating synthetic data sets.

  • Improved API documentation and example for how to use the toolbox as a Java library.

  • Added a command-line interface.

  • Optimization of the non-stationary sources, in order to improve the result in the case where the correlations between s- and n-sources are not time-constant.

  • The objective function has been normalized to make its value interpretable.

  • Methodological appendices have been added to the manual.
