We present optimal parallel QR factorization algorithms with reduced communication overhead. QR factorization is widely applied to solve various problems in numerical linear algebra. Our focus is on ...

Abstract: This paper proposes a QR iteration decomposition-based time reversal multiple signal classification algorithm (QR-MUSIC). By replacing the traditional singular value decomposition (SVD) with ...

TikTok has reached a deal that will allow it to keep operating in the United States, with a majority American-owned joint venture, but the terms could change the algorithm for users in the U.S. The ...

The Federal Bureau of Investigation has issued a warning about a growing cyber threat that turns everyday QR codes into spying tools. According to the bureau, a North Korean government-sponsored ...

[Sketchiest Guy in the World Voice] Hey kid, wanna see the X algorithm? It’s right over here. No really, Elon Musk appears to be partly making good on his promise about a week ago to open up the X ...

In 2023, the website then known as Twitter partially open sourced its algorithm for the first time. In those days, Tesla billionaire Elon Musk had only recently acquired the platform, and he claimed ...
