CWI develops tool for creation of personal video stories

Researchers at CWI have developed software that can automatically create a personalized video story by re-mixing material captured by multiple people at an event. The project, called MyVideos, enables users to share stories from small-scale events with friends and relatives that might not have been there. Researcher Rodrigo Laiola Guimarães will defend his thesis ‘Socially-Aware Multimedia Authoring’ on 28 January 2014 at the VU University Amsterdam.

Bruno Loff defends thesis on computational complexity

CWI researcher Bruno Loff has developed new techniques for determining the complexity of problems that can be solved by a computer. Studying computational complexity provides insight in the inherent difficulty of different types of problems, and the amount of computing power necessary to solve them.

Editie.NL reportage "Emoties, zo 2014"

RTL4 maakte voor Editie.NL de reportage "Emoties, zo 2014",  over de emotieherkennings-demo die binnen het COMMIT/ onderzoeksprogramma SWEET is onwikkeld. Voor het SWEET project heeft de Database Architectures groep van CWI de database technologie geleverd. Alle data die door de verschillende sensors wordt gegenereerd, wordt verzameld in de door CWI ontwikkelde MonetDB database.

PhD research leads to innovation in digital forensics software

In forensics the analysis of digital data faces major challenges. The volume is growing exponentially and there is a wide variety of devices and formats. Jeroen van den Bos, PhD student at the Centrum Wiskunde & Informatica (CWI) in Amsterdam and software engineer at the Netherlands Forensic Institute (NFI), developed a new approach to develop flexible, automated digital forensics software.

New technique detects bugs in object-oriented languages

CWI researcher Stijn de Gouw has developed a new technique for the detection of bugs in software written in object-oriented languages like Java. In a first test case, the technique was able to determine the correctness of complex software of marketing software company SDL Fredhopper.

CWI joins Sino-European research network LIAMA

Centrum Wiskunde & Informatica (CWI) has officially joined research network LIAMA. The Sino-European Laboratory in Computer Science, Automation and Applied Mathematics (LIAMA) is a research lab consisting of European and Chinese research institutes in the field of mathematics and computer science. LIAMA conducts research, training and transfer projects in these fields. CWI will join the lab as one of the founding members.

Conditions for optimal solutions to semidefinite problems found

Most optimization problems in real-life are hard to solve optimally. However, for practical purposes it is usually sufficient to settle for near-optimal solutions that can be found quickly. Fast and more accurate approximations can be computed using semidefinite programming, a novel powerful optimization tool

Jop Briët awarded Andreas Bonn medal

Jop Briët, former researcher at the Centrum Wiskunde & Informatica (CWI) in Amsterdam, was awarded the Andreas Bonn medal for his thesis `Grothendieck Inequalities, nonlocal games and optimization’.

Giannicola Scarpa defends thesis on quantum entanglement

Quantum entanglement, a strong correlation between particles that can exist even over long distances, has far-reaching consequences. Researcher Giannicola Scarpa of Centrum Wiskunde & Informatica (CWI) has studied several of these consequences for information processing and communication.

CWI team wins recommendation challenge

Researchers Arjen de Vries, Alan Said and Alejandro Bellogin from Centrum Wiskunde & Informatica in Amsterdam, scored the highest ranking in the news recommendation challenge that is part of the ACM Recommender System Conference.

NAW publication on Mathematics and Planet Earth

Daan Crommelin (CWI) and Henk Schuttelaars (TU Delft) were guest editors of a special issue of Nieuw Archief voor Wiskunde (NAW) on Mathematics and Planet Earth that was recently published. Daan Crommelin also wrote a blog post for the Daily Blog of the 'Mathematics of Planet Earth 2013' (MPE) website on this special publication. A summary follows below.

Human Brain Project started

The Human Brain Project, the world’s most ambitious neuroscience project, is underway. Scientists from the 135 partner institutions, co-funded by the EU with an estimated budget of €1.2 billion, are meeting in Switzerland for the official launch. Centrum Wiskunde & Informatica (CWI) is one of the partners from the Netherlands and will work on management and analysis of big data streams.
