Struinen in het historische centrum, de faculteit ontdekken en natuurlijk chillen aan het strand. Honderden eerstejaars leren in de HOP-week elkaar en hun nieuwe stad kennen. Voor veel studenten is de week een 'gamechanger'.

‘Vrijwel elke kritische reflectie op AI en de richting waarin AI zich op dit moment ontwikkelt, ontbreekt’, zegt Reijer Passchier, hoogleraar digitalisering en de democratische rechtsstaat aan de OU en universitair docent staatsrecht in Leiden, in een opiniestuk in de Volkskrant.

Waarom laaien er rellen op in het Verenigd Koninkrijk, aangespoord door de extreemrechtse British Defence League? Jorieke Manenschijn sprak met EenVandaag over hoe de beloftes van Brexit aan de woede hebben bijgedragen.

Het recente werkbelevingsonderzoek bood waardevolle inzichten in hoe medewerkers binnen FGGA hun werk en werkomgeving ervaren. Leidinggevenden gingen hierover in gesprek met hun teams. Wat leverde dat op?

Volgens Wim Voermans, hoogleraar staatsrecht, zullen losse erkenningen van landen niet zoveel betekenen. Erkenning is volgens de hoogleraar pas betekenisvol als ook grote spelers als de VS meedoen, zegt hij in NU.nl.

Top scientists of three Dutch universities are working on software and systems for quantum computers. Researchers of the Leiden Institute of Advanced Computer Science (LIACS) and the Leiden Institute of Physics (LION) are developing new algorithms to make those super computers work. The coming years,…

Today, everybody and everything produces data. People produce large amounts of data in social networks and in commercial transactions. Medical, corporate, and government databases continue to grow. Sensors continue to get cheaper and are increasingly connected, creating an Internet of Things, and generating…

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

Nationale Week Zonder Vlees is een landelijke campagne en wordt breed gedragen door diverse partners uit de voedselindustrie!⠀

In this dissertation, we study partition-based models that can be used both for interpretable predictive modeling and for understanding data via interpretable patterns.

Quantum annealing belongs to a family of quantum optimization algorithms designed to solve combinatorial optimization problems using programmable quantum hardware. In this thesis, various methods are developed and tested to understand how to formulate combinatorial optimization problems for quantum…

At Leiden University, researchers from all disciplines work together to find answers and design innovations in the field of artificial intelligence.

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

Dit proefschrift beschrijft een collectie aan alternatieve strategieën voor het begrijpen, ontwerpen en toepassen van lipide nanosystemen, waarin de rol van de bio-nano interacties centraal staan. In het bijzonder wordt gekeken naar de interactie van RNA-lipide nanosystemen, bekend van de toepassing…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

This thesis mainly focuses on multimodal understanding and Visual Question Answering (VQA) via deep learning methods. For technical contributions, this thesis first focuses on improving multimodal fusion schemes via multi-stage vision-language interactions.

Fighting for the faith, caring for the sick, and praying for the soul of their benefactors were the main tasks of the military orders, who since the time of the crusades were well represented in the Netherlands in the Middle Ages, including the Frisian lands. Especially the Hospitallers and the Teutonic…

We are living in an information era where the amount of image and video data increases exponentially.

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.

Reinforcement learning is a framework that enables agents to learn in a manner similar to humans, i.e. through trial and error. Ideally, we would like to train a generalist agent capable of performing multiple tasks and achieving various goals.

This year, the National Clean-up Day, in an adapted form, will take place. Join us and take a clean-up walk on Saturday, March 20.⠀

Do objectively correct solutions to ethical dilemmas exist? Or is ethics always a matter of your opinion against my opinion? How do you know what to do? What kind of thing is ethics anyway? Can you be an expert in ethics?

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.
