AI Definitions: Unsupervised training

Unsupervised training - Just as children mostly learn to explore their world on their own, without the need for too much instruction, in this type of AI training, the AI is turned loose on raw data without a human first labeling the data. Instead of the AI being told what to look for, it learns to recognize and cluster data possessing similar features. This can reveal hidden groups, links, and patterns within the data and is really helpful when the user cannot describe the thing they are looking for—such as a new type of cyberattack. Not as expensive as supervised learning, it can work in real-time but is also less accurate.
