Researchers used a machine-learning algorithm fed with Instagram streams to spot the correlations between depression and images. Depressed individuals prefer bluer, darker images and also received fewer likes than healthy people. Currently the detection rate is at 70 percent, which is a higher rate than GPs are able to identify.
Deep neural networks and machine-learning are key players of artificial intelligence. They are simulating basic information processing of the brain and are more and more used in many products.
