 English term or phrase: pushes up against In Figure 4(b), the hyperplane that classifies Attriters from Non-attriters and those data points that the margin pushes up against are called support vectors. Margin is the minimal distance between the data points and the hyperplane that divides Attriters and Non-attriters. http://www.javaworld.com/javaworld/jw-02-2007/jw-02-jdm.html...

 差量（差量线）上下极限上的（数据）点 Explanation:把两个句子连在一起就好理解了，这两就能把hyperplane, data point, support vector 和margin这几个感念区分开了。Hyperplane是support vector，因为它classifies Attriters from Non-attriters，并且没考虑margin,如原文中Fig4(a)；同样data point也是support vector，因为考虑了margin,如原文中Fig4(b)。为什么考虑margin？因为SVM考虑了或改进了Naive bay 对极小的数据有ingore的情况，而这一改进是通过引入hyperplane和max margin来实现。上面的翻译只是作为参考。我觉得你的问题不在push up against这个词组上，而是在这几感念的区分上。希望这些讲解有些帮助。如果你有更好的想法，一起来讨论讨论。
