WebbAhead geological prospecting, which can estimate adverse geology ahead of the tunnel face, is necessary in the process of tunnel construction. Due to its long detection range and good recognition effect on the interface, the seismic method is widely used in tunnel ahead prospecting. However, the observation space in tunnels is quite narrow compared to … Webbleast-squares method is used to solve the least-squares migration quadratic optimization problem. In other words, the Hessian operator for elastic LSRTM is implicitly inverted via a matrix-free algorithm that only requires the action of forward and adjoint operators on vectors. The diagonal of the pseudo-Hessian operator is used to design a WebbThe Least Squares estimate is defined as the w that min-imizes this expression. This minimization forms a con-tinuously differentiable unconstrained convex optimization problem. Differentiating (3) with respect to w (and dividing by 2) we obtain: XT (Xw ¡y) (4) Since we will need it later, we see that the Hessian of (3) is simply: XT X (5) can mice fit through small spaces
