Aalto’s Mobile Cloud Computing group deepens understanding on the geometrical and operational meaning of sparsity and entropy
In the past hundred years, the measures to compute sparsity, traditionally in the form of entropy, have been characterized and qualified from the physical or operational, and information theoretic perspectives.
In this paper, instead, a classical mathematical approach using equivalence relations has enabled a minimal characterization of sparsity. [...]

Translation models made in Helsinki are now integrated in Hugging Face transformers
Huge contribution has been made to democratize natural language processing. Translation models made in Helsinki are now integrated in Hugging Face transformers, the world’s most popular library for working with deep neural NLP models.
In memoriam: Jorma Rissanen, inventor of arithmetic coding and celebrated information theorist
One of the most accomplished and celebrated Finnish scientists, Jorma Rissanen, passed away at age 87 after a long illness in Los Gatos, California, on 9 May 2020.
Jorma Rissanen’s career and discoveries have been a continuous source of inspiration for generations of researchers and students. He was perhaps best known for his Minimum Description Length (MDL) principle, a fundamental principle of inductive inference. [...]
Multidisciplinary pilot project explored smart textiles and virtual reality in rehabilitation of stroke patients
The mc² – Mobile Cloud Computing group at Aalto University is doing experimental systems research on Virtual Reality (VR) and wearable sensing technologies. In a recent project with Kuopio University Hospital and Savonia University of Applied Science, they explored physical therapy as a potential application area. The idea was to create VR exergames and accompanying […]
FCAI supports the Finnish Government’s new expert group on AI and digitalization
Sirpa Paatero, the Finnish Minister of Local Government, has set up a new expert group on artificial intelligence and digitalization. Several members of FCAI were appointed as the expert group members.
Professor Petri Myllymäki was appointed as a permanent member of the group, while Professor Sasu Tarkoma, who at FCAI leads its collaboration with the 6GFlagship, and Dr. Jaana Leikas, the chairperson […]
Siamese neural networks applied to algorithm selection in recommender systems
The performance of a recommendation algorithm varies in different scenarios, and intuitions about what algorithms are best suited to a given scenario can be elusive even to recommender system experts. Furthermore, choosing a single algorithm that performs well across all the scenarios often reduces the effectiveness of the system in specific scenarios. In the domain of scholarly article recommendation, for example, […]
Foundations of animal-computer interaction explored with monkeys of the Helsinki Zoo
Much like humans, animals have also been using computers for a long time. Historically animals have used computer technology in space, used lexigrams (symbol keyboards) to form language, and dolphins have used underwater keyboards. Drawing parallels to human-computer interaction (HCI) research, which studies how humans use computers, ACI aims to investigate how animals interact with technology and the design of […]
Momentum of the MyData movement continues
The conferences of MyData Global have established their position as the premier events for the rapidly growing community interested in human-centered personal data management. MyData 2019, organised on 25-27 September in Helsinki, brought together 975 participants from 46 countries. The programme was arranged in 9 thematic tracks with “Rebuilding trust – for human-centered […]
Nordita program on Solar Helicities brought together observers, modelers and theorists
Understanding the Sun to the extent that we can predict how its magnetic field drives space weather and climate is an extremely challenging but important problem for the present-day, increasingly hi-tech, society. Key variables in this process are solar helicities, broadly speaking meaning twist of velocity or magnetic field. Magnetic helicity, for example, can be linked to the eruptibility of […]
Automatic dialogue generation demonstrated in an international conference on games
How does natural language generation relate to games? These two concepts that are seemingly far away from each other are surprisingly related. In the 14th International Conference on the Foundations of Digital Games (FDG 2019), two doctoral students of the University of Helsinki, Khalid Alnajjar from computer science and Mika Hämäläinen […]
Thermal cameras hold promise for improved energy management in smart buildings
Improving energy management of buildings is among the most promising application areas of new technology for sustainable living. The Pervasive Data Science Group of the University of Helsinki is experimenting with thermal cameras to gather fine-grained information for use as actionable feedback to heating, cooling and ventilation (HVAC) devices in shared living spaces. The idea is […]
