Witryna11 gru 2024 · The parametric method called curvature-controlled stacking-line method (CCSLM) is performed by changing the magnitude of the sweep or lean. A fourth Bezier spline is adopted to define the curvature of spanwise stacking line directly ensuring surface smoothness. Witryna1 lis 2015 · 3.1. Optimization problem. The first illustration of the method is a very simple optimization problem consisting in minimizing the compliance (maximizing the stiffness) of a square plate presented in Fig. 3. The left side of the plate is clamped and a point force is applied downwards at the lower right corner.
WitrynaIn this post, we have seen 3 methods to build upon gradient descent to combat the problem of pathological curvature, and speed up search at the same time. These methods are often called "Adaptive Methods" since the learning step is adapted according to the topology of the contour. WitrynaStandard first-order stochastic optimization algorithms base their updates solely on the average mini-batch gradient, and it has been shown that tracking additional quan-tities such as the curvature can help de-sensitize common hyperparameters. Based on this intuition, we explore the use of exact per-sample Hessian-vector products
