Each center is randomly assigned a weight, a central point per attribute, and a standard deviation. To generate new instances, a center is chosen at random taking the weights of each center into consideration. Attribute values are randomly generated and offset from the center, where the overall vector has been scaled so that its length equals a value sampled randomly from the Gaussian distribution of the center. The particular center chosen determines the class of the instance.<br/> RandomRBF data contains only numeric attributes as it is non-trivial to include nominal values. <p/> <!-- globalinfo-end --> <!-- options-start --> Valid options are: <p/> <pre> -h Prints this help.</pre> <pre> -o <file> The name of the output file, otherwise the generated data is printed to stdout.</pre> <pre> -r <name> The name of the relation.</pre> <pre> -d Whether to print debug informations.</pre> <pre> -S The seed for random function (default 1)</pre> <pre> -n <num> The number of examples to generate (default 100)</pre> <pre> -a <num> The number of attributes (default 10).</pre> <pre> -c <num> The number of classes (default 2)</pre> <pre> -C <num> The number of centroids to use.
