Here we derive from the underlying mathematical foundation and propose a new class of spectrometer, which harnesses the convolution theorem, one of the most fundamental principles in signal processing ...

The exponential growth of cloud computing and artificial intelligence (AI) applications has driven an urgent need for high-bandwidth, energy-efficient hardware architectures in data centers. With ...

ChatGPT kicked off the AI boom, but it was a landmark partnership between its developer OpenAI and software giant Microsoft Corp. that laid its financial foundations. This playbook has been repeated ...

Sam Altman, the chief executive of OpenAI, says that technological revolutions are driven by more than just technology. They are also driven, he argues, by new ways of paying for them. “There is ...

The AI boom has triggered a historic spending spree. By 2028, investment in chips, servers and data centers could reach nearly $3 trillion, according to Morgan Stanley. On this episode of Bold Names, ...

Skeptics of a recent investment spree involving OpenAI and others say deals raise questions about the robustness of the artificial intelligence boom. By Andrew Ross Sorkin Bernhard Warner Sarah ...

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process. When all the sawdust had ...

We extract more than 100 billion tonnes of raw materials from Earth each year, then throw most of them away. The “circular economy” offers a different approach: instead of the linear “take-make-waste” ...

Understanding how machines interpret visual information starts with two fundamental concepts in image processing: convolution and correlation. These techniques are often mentioned in textbooks, but ...

Having a circular rash can spark fears that you’ve picked up ringworm. After all, the fungal infection is notorious for causing a ring-shaped rash. But there are a lot of other circular rashes that ...

Rana Hajirasouli is a Ph.D. Researcher at the University of Cambridge and Founder of The Surpluss (Certified B Corp). The circular economy has long been heralded as an important pathway to sustainable ...

A windowed sinc function can implement a low-pass filter, and a two-dimensional convolutional filter can blur or sharpen images. In part 3 of this series, we introduced a low-pass filter based on the ...
