College students lead stressful lives. They've got assignments to complete and extracurriculars to attend, not to mention tests to prepare for and job applications to submit. Unfortunately for them, the negative health effects of stress are well-documented. If left untreated, it can cause cardiovascular diseases, affect memory and cognition, and even suppress the immune system. To help suss out the outsized contributors to social and academic pressure, researchers at the College of Computer Science at the University of Massachusetts turned to AI, which they used to predict stress levels -- below median, median, or above median -- from questionnaire and smartphone sensor data.
