Before revision:  We test the performance of our method on a variety of large and high-dimensional data sets .
After revision:  We test the performance of our method on data sets with up to 10 million nodes per layer as well as up to 104 dimensions resulting in graphs with up to 52 layers. While all presented numerical experiments can be run on an average laptop computer, the linear dependence per iteration step of the runtime on the network size makes the algorithm scalable to even larger and higher-dimensional problems .
