Behavioral and neural mechanisms underlying risky decision-making in adolescents

The invention of neural networks marks a critical milestone in the pursuit of true artificial intelligence. Despite their impressive performance on various tasks, these networks face limitations in learning efficiently as they are often trained from scratch.

Research in the Natural Computing and Optimization cluster covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

The lecture series 'Humanity in the Automated State' examines how AI and automated systems are transforming government and public administration and what it means to be human within these digitised institutions.

Leiden University computer scientists Yu Liu, Yanming Guo and Michael Lew are a step closer to their ultimate goal: search engines with visual recognition. Their publication of a new algorithm for fusing multi-scale deep learning representations has been received with great enthusiasm. No other algorithm…

When can a patient be discharged from intensive care? Artificial intelligence can help answer this and other questions. But using such revolutionary technology in healthcare is not easy, as Anne de Hond has discovered.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

In this project, researchers from computer science, law, psychology, and public administration research in practice how artificial intelligence (AI) can be leveraged to make decision-making in the security domain more effective, while also keeping it safe and accountable.

Research in the natural computing group covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

Professor Ton Liefaard has worked to improve the position of children since his academic career began.

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…

Anne Meuwese and Francien Dechesne have received SSH Open Competition M funding from the Dutch Research Council for their joint project 'The Artificial Intelligence Act in action. Probing and improving the quality of legislation in the algorithmic era.'

In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.

We see computer programming as an essential skill. It enables you to be self-sufficient in building tools, processing data, visualizing research output, communicating research results, etc. Moreover, it empowers you to make beautiful things.

Marco Cinelli from Leiden University College (LUC) and the Institute of Environmental Sciences (CML) was awarded the 2024 EURO Award for the Best EJOR Paper at the European Conference on Operational Research in Copenhagen.

The car we buy is made out of thousands of components, which are produced using different types of materials. These materials need to be sourced from different places, sent to production facilities and assembled. Once the car is dismissed, the components need to be taken care of by either reusing, recycling…

This programme is aimed at students who have a strong interest in programming and computer science, as well as an interest in the cognitive psychology and artificial intelligence.

Tic tac toe, but with quantum effects. That makes learning the principles of quantum technology a piece of cake. This is the aim of a new start-up founded by researcher Evert van Nieuwenburg: QuantumPlayed. ‘Quantum is all around us and everyone should be able to learn about it.’

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Lecture

Explore the programme structure of the MSc The Politics of Artificial Intelligence at Leiden University: core courses, elective seminars, internship option, thesis research and real-world AI governance cases.

(1) What are the institutional factors that influence AI adoption and implementation? and (2) How does AI reshape the exercise of administrative discretion within public organisations, and how do adoption and implementation choices moderate these effects?

With the dramatic growth of the image data on the web, there is an increasing demand of the algorithms capable of understanding the visual information automatically.

The Master’s Open Day on 16 March was busy at all faculties in Leiden and The Hague. Thousands of visitors from the Netherlands and abroad came to Leiden University. ‘I want to find out more about the curriculum, and taste the atmosphere,’ said Sarah from Groningen.

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

This article investigates which factors most influence individuals’ decisions to engage in conversations about risk.

In these uncertain times when we all have to adapt to new circumstances, LUC is working hard to develop and implement changes in procedures and guidelines for staff and students. We would like to explain how this is organized, because staff and students are not always aware of the many steps that are…

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

Environmental organisation Greenpeace wants to see a drastic reduction in nitrogen deposition on the Netherlands’ most vulnerable nature conservation areas. This would extend beyond the nitrogen targets that the Dutch government is currently striving to meet. Rogier Kegge, Assistant Professor of Constitutional…
