Solving Random Systems of Quadratic Equations via Truncated Generalized Gradient Flow

The notation φ ( n) = O ( g (n)) means that there is a constant c > 0 such that | φ ( n) | c| g ( n)| . "plain vallina" spectral initialization, its performance still suffers when the number of measurements Stages s1) and s2) are delineated next in reverse order.
