14 дек. 2023 г. · Matrix multiplication is a fundamental computation in modern statistics. It's at the heart of all concurrent serious AI applications.

2.2 Approximating matrix multiplication by random sampling. We will start by considering a very simple randomized algorithm to approximate the product of two.

Freivalds' algorithm (named after Rūsiņš Mārtiņš Freivalds) is a probabilistic randomized algorithm used to verify matrix multiplication.
