Top research

The research at the department combines theory with interaction with the application fields in a well-balanced whole. Both the department and Basic Research Unit in the Helsinki Institute for Information Technology were awarded the highest grade in the research review carried out in 2005. Algodan (Algorithmic Data Analysis) is a national Finnish Academy centre of excellence 2008-2013.

In research, the following key areas will be emphasized in the 2010-12 period:
 
- Data analysis. Method development and applications in modern data analysis: machine learning, data mining, information-theoretic modelling. The research into this topic has long traditions, and the research at the department is a world leader in this area.
 
- Networking and services. Research into networked systems and their premises: middleware (including service and application platforms, management of middleware, trust, and safety), mobility (independence of technology and location, wireless communications), information networks, service networks, context-awareness and ubiquitous computing. This area combines the department's traditional research into wireless and mobile computing with new emerging research themes such as middleware and ubiquitous computing. The focus of the research is moving from protocols towards the problems of the application level and their solutions.
 
-Software research. The research into this area will grow considerably during the next three-year period, both in applied and basic research. The focus of software research is on the global development and processes of software, systems of open source code and web technologies and their utilisation, parallel programming, sustainable software technologies and their applicability. During the strategy period, we will strive for world-class skills and networking in each key area.
 
It is possible that pioneering key areas will be considered during the strategy period. We have, among other opportunities, two vacant professorships that we can direct into new focal areas.

Inter-university research and training centre on information security

The University of Helsinki and Aalto University have set up a joint research centre focusing on information security. The new centre, HAIC (Helsinki-Aalto Centre for Information Security), will coordinate the Master’s-level security education between the university and Aalto, with links to research and doctoral education.

The idea is to build bridges to the industries and gain their support for the education, and e.g. grants for MSc students coming from outside the EU, the head of the Department of Computer Science, Sasu Tarkoma, says.

Computer science undergraduate Petteri Timonen awarded in US science competition

Petteri Timonen, 19, came second in his category of the Intel International Science and Engineering Fair (ISEF) in Phoenix, Arizona.

 

On Friday, 15 May, Timonen, who is studying computer science at the University of Helsinki, was awarded a grant worth 1500 USD, some 1330 euros, in the Systems Software category of the Intel ISEF science competition.
 
As his entry, Timonen submitted a software tool he developed for Finland’s Red Cross to make mobile blood runs around the country as cost-effective as possible. Timonen implemented his tool in cooperation with the Blood Service.

The tool has gained international attention, as no tool like it seems to have been developed anywhere else. Timonen has also negotiated with the American Red Cross by email.

Renewed Carat App Gives a Smart Boost to Battery

 
The Carat Project Team at the University of Helsinki, Department of Computer Science, has published a new version of the popular mobile energy-awareness application.

After launch in June 2012, Carat has helped over 850,000 users, of which 41 per cent have been Android and 59 per cent iOS users, respectively. The new user interface follows modern application design guidelines and presents battery information in a more intuitive and easy to use manner.

- In addition to the new user interface, we have increased the accuracy of the energy saving recommendations of Carat, says Professor Sasu Tarkoma, the leader of this research done at the university.

The user interface features the number of energy intensive applications (Hogs), energy anomalies (Bugs) and user recommendations (Actions) at a glance on the main screen as well as global energy statistics for the device community.

Cover Song Identification Using Compression-based Distance Measures

M.Sc. Teppo E. Ahonen will defend his doctoral thesis Cover Song Identification Using Compression-based Distance Measures on Friday the 1st of April 2016 at 12 o'clock in the University of Helsinki Exactum Building, Auditorium CK112 (Gustaf Hällströminkatu 2b).  His opponent is Academy Professor Petri Toiviainen (University of Jyväskylä) and custos Professor Esko Ukkonen (University of Helsinki). The defence will be held in Finnish.

Measuring similarity in music data is a problem with various potential applications. In recent years, the task known as cover song identification has gained widespread attention. In cover song identification, the purpose is to determine whether a piece of music is a different rendition of a previous version of the composition. The task is quite trivial for a human listener, but highly challenging for a computer.
