UEFA EURO forecast: France will be European Champion
2021-06-07
(Press-News.org) On Friday, 11 June, Europe's men's football teams will start the European Championship a year later than planned. The favourite this time is France with a probability of winning of 14.8 per cent. This is what an international team of researchers consisting of Andreas Groll and Franziska Popp (both TU Dortmund, Germany), Gunther Schauberger (TU Munich, Germany), Christophe Ley and Hans Van Eetvelde (both Ghent University, Belgium), Achim Zeileis (University of Innsbruck, Austria) and Lars Hvattum (Molde University College, Norway) has shown with the help of machine learning. Their forecast combines several statistical models for the teams' strengths with information about the team structure (such as market value, number of Champions League players, club match performance of individual players) as well as socio-economic factors of the country of origin (population and gross domestic product).
100,000 simulations
With the predicted values from the researchers' model, the entire European Championship was simulated 100,000 times: match by match, following the tournament draw and all UEFA rules. This results in probabilities of all teams advancing to the different tournament rounds and ultimately winning the European Championship. The favourite this time is France with a probability of winning of 14.8 per cent, followed by England (13.5) and Spain (12.3). Of course, the tournament is not over - this is also shown by the relatively narrow gaps in the win probabilities at the top, plus of course the already low probability even of the top nations. "It is in the nature of forecasts that they can also be wrong - otherwise football tournaments would be very boring. We provide probabilities, not certainties, and a probability of winning of 15 per cent also means a probability of 85 per cent of the team not winning the tournament," says Achim Zeileis. So far, however, the predictions have been quite successful: Achim Zeileis' Innsbruck model, which is based on adjusted odds from the betting providers, was able to correctly predict the EURO final in 2008, as well as the World and European Champions Spain in 2010 and 2012, among others. This year, it will be used as part of a more comprehensive combined model developed by the teams led by Andreas Groll (TU Dortmund), Gunther Schauberger (TU Munich) and Christophe Ley (Ghent University), which surpassed the forecasting quality of the betting providers at the 2018 World Cup.
Germany in the tournament
It is no secret that the German national team has been drawn into a particularly challenging group this year: "There are three very strong teams in Group F, including the current world champion France and the European Champion Portugal, both also finalists at EURO 2016, plus Germany," explains Andreas Groll: "Compared to the top teams in the other groups, the probability of making it to knockout stage is lower in this group. But those who do make it have a very good chance of advancing further." The forecast sees a probability of 85.3 per cent for both Germany and Portugal to make it to the round of 16; for France, the probability is slightly higher at 89.7 per cent. Germany's probability of becoming European Champion is 10.1 per cent, well below that of the favourites and exactly on a par with Portugal.
Machine learning
The researchers' calculation is based on four sources of information: A statistical model for the strength of each team based on all international matches of the past eight years (Ghent University), another statistical model for the strength of the teams based on the betting odds of 19 international bookmakers (University of Innsbruck), further information about the teams, for example market value, and their countries of origin, such as population size (TU Dortmund and TU Munich), as well as detailed ratings of the individual players and their individual performances both in their home clubs and national teams (Molde University College). The fifth source or "partner" is a machine learning model that combines the other four sources and optimises them step by step. The researchers trained the model on historical data, as Andreas Groll explains: "We fed the model with the current data for the past four European Championships, i.e., between 2004 and 2016, and compared it with the actual outcomes of all matches in the respective tournaments - so the weighting of the individual sources of information for the current tournament will ideally be very precise." In any case, we will find out how well the model performed by the evening of 11 July at the latest.

For years, psychology researchers have treated peer rejection and social network isolation as being somewhat interchangeable when it comes to early adolescence; it was thought that if kids fell into one of those two groups, they fell into the other. A recent study finds there is actually little overlap between the groups - and socially isolated kids face different risks.
"Broadly speaking, there are two types of socially marginalized groups in early adolescence," says Kate Norwalk, lead author of the study and an assistant professor of psychology at North Carolina State University. "There are kids who face peer rejection, meaning they are disliked by other kids; and there are kids who are experiencing social network isolation, meaning they don't have a ...

Many contemporary political conflicts are between those who would prioritize the needs of local or national communities and those with a more universal outlook. According to a new study by IASS researcher Silvia Weko, this split between "communitarian" and "cosmopolitan" Europeans is also evident in their attitudes towards European climate policy. Achieving climate neutrality without exacerbating societal divisions within and between countries will require the EU to strike a careful balance.
In political philosophy cosmopolitans and communitarians are frequently characterized as "winners" and "losers" of globalization. ...

UPTON, NY--What happens when very short pulses of laser light strike a magnetic material? A large international collaboration led by the U.S. Department of Energy's (DOE) Brookhaven National Laboratory set out to answer this very question. As they just reported in the Proceedings of the National Academy of Sciences, the laser suppressed magnetic order across the entire material for several picoseconds, or trillionths of a second. Understanding how magnetic correlations change on ultrafast timescales is the first step in being able to control magnetism in application-oriented ways. For example, with such control, we may be able to more quickly write data to memory devices or enhance superconductivity ...

The lack of data is a major bottleneck for many kinds of research, and especially for the development of better medical treatments and drugs. This data is extremely sensitive and, understandably, people and companies alike are often unwilling to share their information with others.
Researchers at the Finnish Center for Artificial Intelligence have developed a machine learning-based method that produces synthetic data on the basis of original data sets, making it possible for researchers to share their data with one other. This could solve the ongoing problem of data scarcity in medical research and other fields where information is sensitive.
The generated data preserves privacy, remaining similar enough to the original data to be used for statistical ...

Researchers at Queen Mary University of London have tested an algorithm on 700,000 patient records in east London, to find out if the data routinely collected by GPs can reveal cases of Familial Hypercholesterolemia - a leading cause of heart attack in young people.
Familial Hypercholesterolemia (FH) is a condition passed down through families that causes extremely high levels of cholesterol in the blood. Without treatment, it can lead to a heart attack at a very young age. FH affects 320,000 people in the UK, the vast majority of whom are unaware they have it.
One method of detection is the 'FAMCAT' (Familial Hypercholesterolemia Case Assertation Tool) which analyses data in GP records - including ...

The ability of stem cells to fix impaired functions of host tissues after transplantation has been a lifesaving breakthrough in treating previously incurable conditions. Much like a coin toss, however, the fate of the transplanted stem cells is unpredictable. They may choose self-renewal, grow into a different kind of tissue, or die.
Spermatogonial stem cells follow the same stochastic fate of unpredictability in outcomes. But a group of fertility scientists led by Hiroshima University's Yoshiaki Nakamura discovered a new method that has favorably flipped the odds and successfully reversed male infertility in mice -- showing great promise for future applications in regenerating human sperm after cancer treatment ...

Normally, the ACE2 enzyme helps regulate our blood pressure. The enzyme sits on the surface of cells, including cells in the lungs, but in connection with COVID-19 it has been found that ACE2 also functions as a gateway for the virus.
"Different viruses have different ways of accessing our cells - as the virus must, of course, get into the cell to be able to replicate, and the coronavirus uses ACE2 to gain access. For this reason, we're investigating what the concentration of ACE2 means for the course of the disease, if you get COVID-19," explains MD and PhD Tue Wenzel Kragstrup from the Department of Biomedicine at Aarhus University. The preliminary results have just been published in the scientific journal PLOS ONE.
As mentioned, ACE2 is part of the surface of the cells, but ...

Jet packs, robot maids and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power sources.
"I think flying cars have the potential to eliminate a lot of time and increase productivity and open the sky corridors to transportation," said Chao-Yang Wang, holder of the William E. Diefender Chair of Mechanical Engineering and director of the Electrochemical Engine Center, Penn State. "But electric vertical takeoff and landing vehicles are very challenging technology for the batteries."
The researchers define the technical requirements ...

Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they're known for being tough, capable of surviving through drying, freezing, starvation, and low oxygen. Now, researchers reporting in the journal Current Biology on June 7 have found that not only can they withstand being frozen, but they can also persist for at least 24,000 years in the Siberian permafrost and survive.
"Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis, the state of almost completely arrested metabolism," says Stas Malavin ...
