% ANDRDEMO demo on Generalized Anderson's task.%% ANDRDEMO demonstrates the algorithms which solve % the Generalized Anderson`s Task (GAT). %% The found solution (hyperplane, line in 2D) is vizualized % as well as the input Gaussians which describe input classes.%% Following algorithms can be tested:% % e-Optimal - Epsilon-solution of the GAT.% Original - Original Anderson-Bahadur's solution for two distributions.% Gradient - Algorithm using theorem of the generalized gradient methods.% General - Implementation of general algorithm framework by SH10.% General2 - Implementation of general algorithm framework, improved.%% Control:% Algorithm - select algorithm for testing.% Parameter input line - parameters for the selected algorithm% (see help 'given algorithm').% Iterations - number of iterations in one step.% Animation - enable/dissable animation.%% FIG2EPS - export screen to the PostScript file.% Load data - load input point sets from file.% Create data - call interactive program for creating sets of Gaussians.% Reset - set the tested algorithm to the initial state.% Play - run the tested algorithm.% Stop - stop the running algorithm.% Step - perform only one step.% Info - display the info box.% Close - close the program.%% See also EANDERS, OANDERS, GGANDERS, GANDERS, GANDERS2.%% Statistical Pattern Recognition Toolbox, Vojtech Franc, Vaclav Hlavac
