weka.gui.boundaryvisualizer.BoundaryVisualizer
BoundaryVisualizer. Allows the visualization of classifier decision boundaries in two dimensions. A supplied classifier is first trained on supplied training data, then a data generator (currently using kernels) is used to generate new instances at points fixed in the two visualization dimensions but random in the other dimensions. These instances are classified by the classifier and plotted as points with colour corresponding to the probability distribution predicted by the classifier. At present, 2 * 2^(# non-fixed dimensions) points are generated from each kernel per pixel in the display. In practice, fewer points than this are actually classified because kernels are weighted (on a per-pixel basis) according to the fixexd dimensions and kernels corresponding to the lowest 1% of the weight mass are discarded. Predicted probability distributions are weighted (acording to the fixed visualization dimensions) and averaged to produce an RGB value for the pixel. For more information, see
