非平衡数据集的分类问题经常出现在许多实际应用中.支持向量机在处理这一类问题时,整体分类性能比较低.为此,Veropoulos提出的采用不同惩罚系数的改进算法可以较好的解决此类问题.此外,可以利用序列最小优化算法简单快速的解决上述优化问题.(Non-equilibrium data sets classification problems often appear in many practical applications. Support Vector Machine in dealing with this type of issue, the overall classification performance is relatively low. To this end, Veropoulos proposed punishment coefficient using different algorithms can improve the better solution such issues. In addition, can use the Sequential Minimal Optimization algorithm is simple and fast solution to the above optimization problem.)

RigidBody
关于演示旋转的一个应用程序,可以更好的理解体旋转的过程(The project is made by using GUIDE of Matlab 7.5.0 (R2007b) and user-defined classes.
The project may be used on the seminars on mechanics in the technical educational establishments. Rigid body section of a course of mechanics is considered as required in most technical colleges and
Universities.
Sometimes it s difficult to imagine a rotation of a rigid body in the three-dimensional space. Especially, when
an asymmetric top is in question. Rigid Body project may help students to see the rotations clearly as though they were in the real world.
