On the other hand, carbon fixation rates may be stoichiometrically higher than expected, based on the elemental ratio of cells, if car- bon is used as ballast for vertical
But strong convexity is a more powerful property than convexity : If we know the value and gradient at a point x of a strongly convex function, we know a quadratic lower bound for

As a novelty, the sign gradient descent algorithm allows to converge in practice towards other minima than the closest minimum of the initial condition making these algorithms
On multiple datasets, we demonstrate that learning self symmetry maps with a deep functional map projects 3D shapes into a low dimensional canonical embed- ding that
Normally, the deterministic incremental gradient method requires a decreasing sequence of step sizes to achieve convergence, but Solodov shows that under condition (5) the
