"Rather than being "taught" medical knowledge, the AI was asked to learn using unsupervised deep neural networks, known as autoencoders, without being given any medical knowledge. The researchers developed a method for translating the features found by the AI-only numbers initially-into high-resolution images that can be understood by humans."

""Deeply disturbing" research exposes how easy it is for children to encounter inappropriate content and interact unsupervised with adults on the gaming platform Roblox. It comes as parents shared their serious concerns about children experiencing addiction, seeing traumatising content and being approached by strangers on the hugely popular website and app. Roblox acknowledges that children using the platform may be exposed to harmful content and "bad actors". It says it is working hard to fix this, but that industry-wide collaboration and government intervention are needed."

"A robot, trained for the first time by watching videos of seasoned surgeons, executed the same surgical procedures as skillfully as the human doctors. The successful use of imitation learning to train surgical robots eliminates the need to program robots with each individual move required during a medical procedure and brings the field of robotic surgery closer to true autonomy, where robots could perform complex surgeries without human help."
