How the AI Behind Deep Fakes Could Improve Cancer Diagnoses

Not that that negates the damage deep fakes can do to medical science, interpersonal communications - and democracy. JL


Karen Hao reports in MIT Technology Review:

Deep-learning algorithms are excellent at pattern-matching in images; they can be trained to detect different types of cancer in a CT scan, differentiate diseases in MRIs, and identify abnormalities in an x-ray. But because of privacy concerns, researchers often don’t have enough training data. This is where GANs come in: they can synthesize more medical images that are indistinguishable from the real ones, effectively multiplying a data set to the necessary quantity.
Generative adversarial networks, the algorithms responsible for deepfakes, have developed a bit of a bad rap of late. But their ability to synthesize highly realistic images could also have important benefits for medical diagnosis.

But because of privacy concerns, researchers often don’t have enough training data. This is where GANs come in: they can synthesize more medical images that are indistinguishable from the real ones, effectively multiplying a data set to the necessary quantity.
There is another challenge, though. Deep-learning algorithms need to train on high-resolution images to produce the best predictions, yet synthesizing such high-res images, especially in 3D, takes a lot of computational power. That means it requires special and expensive hardware, making its large-scale use impractical in hospitals.
So researchers from the Institute of Medical Informatics at the University of Lübeck proposed a new approach to make the process much less intensive. They broke it up into stages: the GAN first generates the whole image in low-res, then generates the details at the right resolution one small section at a time. Through experiments, the researchers showed not only that their method generated realistic high-res 2D and 3D images with low computational resources, but that the expenditure also stayed constant regardless of image size.
