Our method can be used to train implicit probabilistic models (a common example being the generator in GANs). Unlike GANs, however, our method does not suffer from mode collapse/dropping and is stable to train. As a result, we are able to generate different predictions for the same input. Below are two applications that take advantage of this capability.
Below are the different high-resolution images generated by our method for the same low-resolution image:
