How do museum visitors interpret the authenticity of museum objects? How can we support visitors' meaningful interactions with real objects?

The League of European Research Universities (LERU) calls for greater appreciation of fundamental research that does not have an immediate application. A working group headed by Geert de Snoo, dean of the Leiden Faculty of Science, issued a memorandum on the subject on 29 August.

The active learning ambition is based on the idea that knowledge is more likely to ‘stick’ when students are actively engaged with their learning and research. This active student participation has implications for how we teach: less consumption of knowledge and more efficient use of contact hours.

The ambition to have flexible learning pathways is about creating possibilities to improve the content and form of students’ learning process, and to link learning to students’ needs. Students who have access to a flexible range of learning pathways can align their university career with their own personal…

Sewer pipes are an essential infrastructure in modern society and their proper operation is important for public health. To keep sewer pipes operational as much as possible, periodical inspections for defects are performed.

The Centre for Professional Learning (CPL) develops in-depth and challenging programmes for higher educated professionals.

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

LLInC supports innovative and high-quality education both within Leiden University and in partnership with academic and social organisations.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…
