Using tweets from 2009-2021, researchers have developed a predictive model that can detect extremist users and content related to the militant group 'Islamic State' (ISIS). Their work could help social media companies identify and eventually restrict such accounts in a timelier manner and abate their impact on online communities, they said. The researchers from the Pennsylvania State University, US, identified potential propaganda messages and their characteristics and developed an image classifier to find the most…

An AI-driven system was found to be able to recognise facial expressions conveying emotions such as happiness and sadness, even fleeting ones, that researchers say could help support psychotherapy.The AI system that the researchers used for the study was a freely available artificial neural network trained to detect six basic emotions - happiness, surprise, anger, disgust, sadness and fear - using more than 30,000 facial photos. Artificial neural networks are a type of machine learning, a sub-field of AI, and are built…
