The deployment of robot teams could allow humans to complete various real-world tasks faster and more efficiently. For instance, multiple co-operating robots could help to quickly find and rescue survivors of natural disasters or monitor pollution across large geographical areas. Researchers at Université Libre de Bruxelles (ULB) have developed a new swarm architecture inspired by […]
Author: Ambuj Tewari, Professor of Statistics, University of Michigan Over 100 years ago, Alexander Graham Bell asked the readers of National Geographic to do something bold and fresh – “to found a new science.” He pointed out that sciences based on the measurements of sound and light already existed. But there was no science of […]
In probability theory and statistics, a collection of random variables is independent and identically distributed (iid) if each random variable has the same probability distribution as the others and all are mutually independent. Most supervised machine learning methods assume that training and testing or production samples are drawn iid from the same underlying distribution. But […]

At a time when the mass media are full of predictions about the apocalyptic effect that AI will have on humanity, it is comforting to read two essays that show that the reality, for the moment, points in the opposite direction. The first of these reveals the excellent results that the application of natural language […]
In the mid-1990s, there was research going on at Stanford University that would change the way we think about computers. The Media Equation experiments were simple: participants were asked to interact with a computer that acted socially for a few minutes after which, they were asked to give feedback about the interaction. Participants would provide […]
Imagine running on a cement footpath, and then suddenly through dry sand. Just to keep upright, you would have to slow down and change the way you run. In the same way, a walking robot would have to change its gait to handle different surfaces. Generally, we humans and most robots can only change how […]
Photo: Gary Bendig / Unsplash We have developed four-winged bird-like robots , called ornithopters, that can take off and fly with the agility of swifts, hummingbirds and insects. We did this by reverse engineering the aerodynamics and biomechanics of these creatures. Our ornithopters have the potential to outperform and outmanoeuvre existing drone configurations with static […]
Robots used to be restricted to heavy lifting or fine detail work in factories. Now Boston Dynamics’ nimble four-legged robot, Spot, is available for companies to lease to carry out various real-world jobs, a sign of just how common interactions between humans and machines have become in recent years. And while Spot is versatile and […]

One thing is designing an object in a computer, and another, quite different, is producing it as a real 3D object. All other things being equal, in general the more curves the designed object has, the more difficult it is to produce. Mathematics can be very helpful in this task. The geometric modeling of a […]
Several researchers in the field of artificial intelligence (AI) are warning about an AI winter, which means that scientists might lose the interest on the discipline, institutions reduce drastically the funding towards its research and lose presence in the public debate. It wouldn’t be the first AI winter though. The last two decades have been […]
