Optimality in plant properties and processing.

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

The programme will give you the opportunity to choose from a broad range of topics to study. You will be part of an international multidisciplinary research team at our institute.

Our programmes are known for our scientifically based education and for our open atmosphere.

This thesis probes under what conditions quantum computing presents an advantage over classical computing.

Existing work in probabilistic language modeling can be mostly divided into two categories:

Modern society is connected through electronic and mobile devices, which we call the Internet of Things (IoT).

With the emergence of online social networks (OSNs), the way people create and share information has changed, which becomes faster and broader than traditional social media.

Structural variants (SVs) are the hidden architecture of the human genome, and are critical for us to understand diseases, evolution, and so on.

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.

SAILS is a university wide initiative aimed at facilitating collaboration across disciplines on the use of Artificial Intelligence (AI).

The Leiden Institute of Advanced Computer Science (LIACS) aims on doing applied research with partners. You can be involved in our research, and in the knowledge transfer of our research results.

This interdisciplinary project applies data science techniques to qualitatively and quantitatively visualize the interaction between the University and the city of Leiden (Town&Gown) from 1575 onwards. One of the possible angles for follow-up research is diversity, especially from the international…
