The stand alone G-KSG method is implemented in "code/G_KSG.R" and can be called with its default parameters given X,Y (both matrices) and k (typically equal to 3). For an example on how to apply the method, see "code/run_example.R". To execute the code, it is assumed that you are in the "code" direktory.

The files for running experiments are in the folder code/experiments.

To execute the code, you must, however, be in the directory "code" (not in "code/experiments").

The experiments for increasing number of samples, which document the runtime are in file "evaluate_runtime_and_accuracy_per_sample.R" and all other experiments can be executed from "run_test.R" by setting the described parameters accordingly.
