双闭环

说明：  计算离散变量x的熵。 输入整数向量和输出z：熵 有益于学习(Compute entropy of a discrete variable x. with Input of a integer vectors and Output of z: entropy good for learning)

说明：  1. 定义了刀具和工件结点的接触，并定义为默认“硬接触” 2. 工件上表面定义了自接触，防止切屑穿透工件上表面 3. 有些情况下可能产生工件右边界的部分结点卷曲后进入上表面，可以额外定义工件上表面与右边界部分结点（在右边界上，但是被切下来的部分结点）的接触算法这样就不会穿透了。(1. Defined the contact between tool and workpiece node, and defined as the default "hard contact". 2. Self-contact is defined on the upper surface of the workpiece to prevent the chip from penetrating the upper surface of the workpiece 3. In some cases, part nodes of the right boundary of the workpiece may curl into the upper surface, and the contact algorithm between the upper surface of the workpiece and the right boundary part node (the part node on the right boundary, but the part node cut off) can be defined in addition, so as not to penetrate.)

说明：  利用卷积神经网络对遥感图像进行分类，能够有效提高分类效率(Classification of Remote Sensing Images by Convolutional Neural Network)
