  • Online training helps preemies

    An international team of researchers has now found that computerized training can support preterm children’s academic success. In their randomized controlled study ‘Fit for School’, the researchers compared two learning apps. Every 11. baby is born too early in Germany, over 15 million globally each year. Although survival rates have increased, long-term development has not…

  • Deep learning can fool listeners by imitating any guitar amplifier

    A study demonstrates that digital simulations of guitar amplifiers can sound just like the real thing. The implications are that as the software models continue to improve, they can replace traditional analogue guitar amplifiers, which are bulky, fragile and expensive. Professor Vesa Valimaki explains that this is an exciting development in deep learning, ‘Deep neural…

  • Artificial intelligence as a co-driver

    Artificial intelligence (AI) is becoming more common in many branches of industry and online retailing. Traditional lines of work, such as transport logistics and driving, are developing in a similar direction. Scientists have now investigated how efficient the use of AI is in the commercial management of trucks. Their answer: the best option is an…

  • With deep learning algorithms, standard CT technology produces spectral images

    Engineers have demonstrated how a deep learning algorithm can be applied to a conventional computerized tomography (CT) scan in order to produce images that would typically require a higher level of imaging technology known as dual-energy CT. In research published today in Patterns, a team of engineers led by Wang demonstrated how a deep learning…

  • All-optical method sets record for ultrafast high-spatial-resolution imaging: 15 trillion frames per second

    Scientists have recently developed an all-optical ultrafast imaging system with high spatial and temporal resolutions, as well as a high frame rate. Because the method is all-optical, it’s free from the bottlenecks that arise from scanning with mechanical and electronic components. Among the various parameters in photography, the sequential imaging of microscopic ultrafast dynamic processes…

  • Deep learning techniques teach neural model to ‘play’ retrosynthesis

    Chemical engineers have trained a neural network model to plan synthetic routes to any target molecule, optimizing user-specified objectives such as cost, time, and sustainability. Organic chemists generally work backwards from the target molecule to the starting materials using a process called retrosynthetic analysis. During this process, the chemist faces a series of complex and…

  • Extending Wi-Fi range for smart-home devices

    A group of researchers has created a protocol that significantly extends the distance a Wi-Fi enabled device can send and receive signals. The engineering innovation requires no new hardware to enhance the signal range for ‘Internet of things’ devices, like a door sensor or motion detector, but can extend the distance these devices can be…

  • How social movements can use virtual worlds

    Online virtual worlds can help social movements raise awareness and create safe spaces for their members, according to a new study. The research examined how an LGBT group used a virtual world for their own cause, which was different to its intended design. The research examined how an LGBT group used a virtual world for…

  • Skat and poker: More luck than skill?

    Chess requires playing ability and strategic thinking; in roulette, chance determines victory or defeat, gain or loss. But what about skat and poker? Are they games of chance or games of skill in game theory? This classification also determines whether play may involve money. Economists have studied this question and developed a rating system similar…

  • Getting real with immersive sword fights

    Sword fights are often the weak link in virtual reality (VR) fighting games, with digital avatars engaging in battle using imprecise, pre-recorded movements that barely reflect the player’s actions or intentions. Now a team has found a solution to the challenges of creating realistic VR sword fights: Touche — a data-driven computer model based on…
