How can humans and computers learn from data? To research this, scientists often use so-called Bayesian methods. Although these methods are widely used, they also have limitations and are not always easy to interpret. In her dissertation Rianne de Heide describes some of these problems and introduces…

Preventing or delaying disease often requires lifestyle changes, which turns out to be difficult. Valentijn Visch and Sandra van Dijk are researching how to help people change their behaviour.
