New tool reveals ultimate owners of companies

Researchers from Skoltech, the European University at St. Petersburg, and Lomonosov Moscow State University have developed an algorithm that detects the ultimate controlling owners of companies. Applicable to datasets with ...

Image: Hubble spots squabbling galactic siblings

A dramatic triplet of galaxies takes center stage in this image from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational tug-of-war between interacting galaxies. This system—known as Arp 195—is ...

AI reveals unsuspected math underlying search for exoplanets

Artificial intelligence (AI) algorithms trained on real astronomical observations now outperform astronomers in sifting through massive amounts of data to find new exploding stars, identify new types of galaxies and detect ...

Maths brilliance in systems engineering

"I was trained as an applied mathematician with a strong emphasis on statistics as a student at Dhaka University, Bangladesh. It transpired that this is not a common combination and I then went on to do my PhD at Loughborough ...

Solving 'barren plateaus' is the key to quantum machine learning

Many machine learning algorithms on quantum computers suffer from the dreaded "barren plateau" of unsolvability, where they run into dead ends on optimization problems. This challenge had been relatively unstudied—until ...

Quantum algorithm could help AI think faster

One of the ways that computers think is by analysing relationships within large sets of data. An international team has shown that quantum computers can do one such analysis faster than classical computers for a wider array ...
