adaptive convergence

In this paper, the smoothness of image is ( locally) controlled by an adaptive weight matrix included in the regularization item, and the convergence is improved by conjugate gradient method.

该方法对正则项进行空间自适应加权从而局部地控制图像的平滑性，并用共轭梯度运算来改善算法的收敛性。

To guarantee the fast convergence of the proposed neural network model, the optimal adaptive learning rates are derived in the sense of discrete-type Lyapunov stability.

在离散型Lyapunov稳定性的意义下，导出了权值自适应学习速率的取值范围，保证控制系统的快速收敛。

On the one hand, to improve the convergence accuracy and speed, an adaptive pressure was added to the external force of the generalized GVF Snake. On the other hand, the edge map was obtained by the proposed edge detection method. 3.

该算法一方面在广义的GVF Snake外力场部分增加了自适应梯度变化的压力，以提高算法的收敛精度及速度；另一方面采用上文提出的边缘检测算子计算边缘图。
