Researchers at NVIDIA, Aalto University, and MIT, have developed a deep-learning AI that can fix photos by just looking at examples of corrupted photos only, or in this case grainy images. Simply put, a neural network is shown example pairs of noisy and clean images, and then the AI learns how to make up the difference. Utilizing NVIDIA Tesla P100 GPUs with the cuDNN-accelerated TensorFlow deep learning framework, the team trained their system on 50,000 images in the ImageNet validation set.

[The neural network] is on par with state-of-the-art methods that make use of clean examples – using precisely the same training methodology, and often without appreciable drawbacks in training time or performance,” said the researchers in their paper.
