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 ...

While the creation of this new entity marks a big step toward avoiding a U.S. ban, as well as easing trade and tech-related tensions between Washington and Beijing, there is still uncertainty ...

Back in July, Google widely introduced a redesign of the Android QR code scanner, but then rolled it back. The updated interface is now starting to reappear. This is the QR code scanner available from ...

A newly-discovered malicious package with layers of obfuscation is disguised as a utility library, with malware essentially hiding in plain sight in embedded QR codes. QR codes are ubiquitous these ...

Kelley Cotter has received funding from the National Science Foundation. Chinese tech giant ByteDance finalized its agreement to sell a majority stake in its video platform TikTok to a group of U.S.

Add the Householder algorithm, which is generally considered superior to Gram-Schmidt, especially for ill-conditioned matrices. I'm not sure if there is a big difference in arbitrary-precision ...

As previewed last year, Google Messages is beginning to roll out QR code-based key verification to confirm that you’re “communicating with the person you intend to.” Once available, open a ...

Sharat Potharaju is cofounder and CEO of Uniqode, whose vision is to enable digital connection with every physical object and place. QR codes drive 37% click-through rates, while email campaigns ...

Dozens of machine learning algorithms require computing the inverse of a matrix. Computing a matrix inverse is conceptually easy, but implementation is one of the most challenging tasks in numerical ...

LinkedIn's algorithm prioritizes ads & sponsored content, hurting organic reach for creators. To adapt: share niche expertise, use authentic images, craft strong hooks, write longer comments, engage ...
