Show me your Twitter feed and I’ll tell you what your problem is
Data scientist Marijn ten Thij studies human behaviour on the basis of messages posted on social media. For example, he mapped the changing mood during the corona pandemic using 3.5 million tweets. The analysis of this kind of data is not only socially relevant, it could also help individuals in psychological distress.

Putting the Human Back into the Algorithm
Putting the Human Back into the Algorithm
Is AI our only hope for the future of humankind? Professor Sami Kaski explores how this powerful tool could help meet the challenges facing our world. But how do we ensure that the human is present in the machine? Artificial Intelligence (AI) is all around us. From the smart watches we wear everyday collecting our personal biodata to helping medical professionals prescribe to patients, this technology has the potential to greatly advance global health services, to name just one area, in the future.

New attacks on computer systems: TU Graz publishes details of Æpic Leak and SQUIP
By Birgit Baustädter International IT security research teams headed by Daniel Gruss of TU Graz have released information on two new forms of cyberattack that exploit hardware. Reliable, bug-free computer hardware provides the foundation for secure software. Now, vulnerabilities on the hardware side are increasingly attracting the attention of hackers and developers alike, not least following the discovery of the Meltdown and Spectre side-channel attacks by TU Graz researchers in 2018.

Quantum Machine Learning enters the fray in CERN’s LHCb experiment
In a recent article in the Journal of High Energy Physics (JHEP), the LHCb collaboration reports the application of Quantum Machine Learning for identifying properties of so-called jets: streams of particles that result from particle collisions. It is the first paper to describe the application of quantum computing to the identification of jets originating from beauty quarks or anti-quarks, a type of particle of particular interest to the LHCb experiment.

New diabetes monitor can detect glucose levels using breath
A next-generation diabetes monitor that analyses breath might soon mean no more needle pricks to check blood sugar levels. The device uses gas sensors to measure breath instantly, then links via Bluetooth with a program on a mobile device to give a readout. Distinct biomarkers in exhaled breath carry a subtle signature that the device picks up before the app uses a deep learning algorithm to produce rapid individual results.

Video games: posing in 3D
An UdeM computer scientist and his PhD candidate have developed a tool for animators to use bitmap sketches to control how a character stands and moves in three dimensions. What's the best way to get 3D characters in videogames to look real and expressive? Two computer scientists at Université de Montréal have come up with answer: use simple bitmap sketches to make their poses more lifelike.

Hey Siri: How Much Does This Galaxy Cluster Weigh?
It's been nearly a century since astronomer Fritz Zwicky first calculated the mass of the Coma Cluster, a dense collection of almost 1,000 galaxies located in the nearby universe. But estimating the mass of something so huge and dense, not to mention 320 million light-years away, has its share of problems - then and now.

Curtin-developed machine learning 'phones home' for famous Martian rock
Curtin-developed machine learning ’phones home’ for famous Martian rock
New Curtin-led research has pinpointed the exact home of the oldest and most famous Martian meteorite for the first time ever, offering critical geological clues about the earliest origins of Mars. Using a multidisciplinary approach involving a machine learning algorithm, the new research – published today in Nature Communications – identified the particular crater on Mars that ejected the so-called 'Black Beauty' meteorite, weighing 320 grams, and paired stones, which were first reported as being found in northern Africa in 2011.
