Het Sport Data Center (SDC) bestaat uit de data science disciplines van de Universiteit Leiden en de TU Delft, in combinatie met sportwetenschappelijke takken van het Amsterdam Institute of Sport Science en het Sports Engineering Instituut van de TU Delft.

De beroepsperspectieven voor informatici op wetenschappelijk niveau zijn zeer gunstig, en de kennis over (bedrijfs)economie opgedaan bij Informatica & Economie komt goed van pas.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

Vandaag de dag liggen statistische methodes aan de grondslag van beslissingen in allerlei facetten van het leven, van de gezondheidszorg en agricultuur tot de financiële sector en marketing.

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

The ultimate goal of cosmologists is to find a cosmological model able to explain the current observational data.

Data theory research on the analysis on the multidimensional data

Het Leiden Institute of Advanced Computer Science (LIACS) verzorgt het bachelor- en masteronderwijs voor informatica aan de Universiteit Leiden.

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

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.

Medewerkers van de sectie Methodologie & Statistiek zijn lid van verschillende commissies.

De Computers, Privacy and Data Protection Conference (CPDP) is 's werelds toonaangevende multidisciplinaire evenement op het gebied van privacy en gegevensbescherming. CPDP brengt experts samen om de allernieuwste juridische, regelgevende, academische en technologische ontwikkelingen op dit gebied te…

The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

The overarching clinical aim of this thesis was to improve pharmacological pain management by characterizing the pharmacodynamics of analgesics. This promotion has been awarded the predicate cum laude.

Databases in het kader van het onderzoeksproject Zelfredzaamheid en sociale bescherming over de levenscyclus (aug 2017 – aug 2022).

Verantwoorde AI voor een sterke en veerkrachtige samenleving en wetenschap.

'Vertel me iets wat ik nog niet weet', zei schaatstrainer Jac Orie tegen de Leidse datawetenschapper Arno Knobbe. Dat lukte; inmiddels ondersteunen Knobbe en zijn collega's sporters op allerlei manieren met behulp van data mining.

Je kunt aan de Universiteit Leiden Kunstmatige Intelligentie studeren, maar ook binnen andere opleidingen speelt het een steeds grotere rol.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

In de opleidingsvideo over de bachelor Informatica krijg je een goed beel van de studie en hoe het programma eruit ziet. Ontdek het hier.

In this thesis I highlight the applications of Oxford Nanopore Technologies (ONT) sequencing. This technique is a relatively new approach in the sequencing field, where nanopores are embedded in a membrane, DNA molecules are pulled through nanopores and an electrical current serving as the sequencing…

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

This thesis investigates the contribution of quantum computers to machine learning, a field called Quantum Machine Learning. Quantum Machine Learning promises innovative perspectives and methods for solving complex problems in machine learning, leveraging the unique capabilities of quantum computers…

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.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…
