Proposed is a theoretically exact formula for inversion of data obtained by a spiral computed tomography (CT) scan with a two-dimensional detector array. The detector array is supposed to be of ...

DeepMind breaks 50-year math record using AI; new record falls a week later AlphaTensor discovers better algorithms for matrix math, inspiring another improvement from afar.

In this way, researchers have discovered new algorithms that multiply n -by- n matrices using fewer than the standard n3 multiplication steps for many small matrix sizes. But algorithms that ...
