Researchers at the University of Helsinki have developed a technique, using artificial intelligence, to analyse opinions, and draw conclusions using the brain activity of groups of people. This technique, which the researchers call "brainsourcing," can be used to classify images or recommend content, something that has not been demonstrated before. Crowdsourcing is a method to break up a more complex task into smaller tasks that can be distributed to large groups of people and solved individually. For example, people can be asked if an object can be seen in an image, and their responses are used as instructional data for an image recognition system. Even the most advanced image recognition systems based on artificial intelligence are not yet fully automated.
