%       A = GLASS

% Load the dataset in A. This is a 4-class version of the originally
% 7-class dataset describing the chemical components in several types of
% glasses. The original class 4 is not available and we combined the
% classes 5-7 as 'Other'.
% BuildingFloat:   -- building_windows_float_processed
% BuildingNonFloat:-- building_windows_non_float_processed
% Car:             -- vehicle_windows_float_processed
