‘We hopen dat ons artikel de mogelijkheden en voordelen laat zien van het gebruik van kunstmatige intelligentie in de quantumfysica om nieuwe ontdekkingen te doen.’ Vedran Dunjko van het Leiden Institute of Advanced Computer Science droeg bij aan een artikel dat vorig jaar verscheen in PNAS. Het artikel…

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Als gevolg van de grote technologische vooruitgang in de gezondheidszorg worden in toenemende mate gegevens verzameld tijdens de uitvoering van klinische onderzoeken.

Transport inspectorates are looking for novel methods to identify dangerous behavior, ultimately to reduce risks associated to the movements of people and goods. We explore a data-driven approach to arrive at smart inspections of vehicles.

The research in this dissertation aims to optimise blood donation processes in the framework of the Dutch national blood bank Sanquin. The primary health risk for blood donors is iron deficiency, which is evaluated based on donors' hemoglobin and ferritin levels.

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

Leiden University and the Ministry of Infrastructure and Water Management are involved in a collaboration in the form of a research project titled 'Data-Driven Risk Assessment in Infrastructure Networks'

In this thesis, we examine various systems through the lens of several numerical methods.

In dit artikel onderzoeken Barrie Sander en zijn collega's of eerlijkheid in digitaal bestuur onbedoeld structurele ongelijkheden verankert.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

Uncertainty and noise are frequently-encountered obstacles in real-world applications of numerical optimization. The practice of optimization that deals with uncertainties and noise is commonly referred to as robust optimization.

Mining time series is a machine learning subfield that focuses on a particular data structure, where variables are measured over (short or long) periods of time.

In this work, we attempt to answer the question:

Software development is a complex process. It is important that software products become stable and maintainable assets.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

Een intelligente vertaalmachine gebaseerd op nieuwe ontwikkelingen in machine learning gaat de concurrentie aan met grote vertaalservices als die van Google. Maar ook Google maakt grote vorderingen sinds het is het is overgestapt op deep learning, aldus informatica-onderzoeker Suzan Verberne in de V…

More than 5,000 exoplanets have been found over the past couple of decades. These exoplanets show a tremendous diversity, ranging from scorching hot Jupiters, common super-Earths, to widely separated super-Jupiters on the planet/brown dwarf boundary.

NRC bespreekt met vier universiteiten de braindrain die zich in Nederland op het gebied van kunstmatige intelligentie (AI) afspeelt.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

Reinforcement learning, agents en classificatie: dit zijn slechts enkele van de onderwerpen die onderzoekers op de BNAIC/BeneLearn-conferentie 2020 hebben besproken. Het was de eerste keer dat de Universiteit Leiden als gastheer optrad voor de jaarlijkse Belgisch Nederlandse Kunstmatige Intelligentie…

Prof.dr. Peter Grünwald, hoogleraar Statistisch leren, heeft donderdag 8 april de Van Dantzigprijs uitgereikt gekregen, de hoogste Nederlandse prijs voor statistiek en besliskunde.

Europa ligt op het gebied van kunstmatige intelligentie achter op China en de Verenigde Staten, wat zorgt voor een brain drain van talentvolle studenten en wetenschappers. Een hoogstaand onderzoeksinstituut voor kunstmatige intelligentie kan het tij keren, aldus initiatiefnemer Holger Hoos, hoogleraar…

Industrial manufacturing processes, such as the production of steel or the stamping of car body parts, are complex semi-batch processes with many process steps, machine parameters and quality indicators.

Zeeschepen stoten nog te veel stikstofoxiden uit. Op volle zee is dat onmogelijk te meten, maar dat gaat veranderen. Solomiia Kurchaba combineerde (satelliet)data en ontwikkelde algoritmen om te kunnen aanwijzen welk schip te veel uitstoot. Kurchaba promoveerde 11 juni.
