LOS ANGELES – Suddenly, they're popping up everywhere — those square, futuristic-looking matrixes that appear to be a cross between abstract art and Rorschach tests.
We achieve efficiency by updating the square-root information matrix, a factored version of the naturally sparse smoothing information matrix.
