你这么一改，我发现我原来的长句要表达的意思出错了，惭愧啊。
accuracy or minimazation of cost is not only oneindicator to evaluate the Performance of the classifier. Higher complexity usually leads to poor performance even no performance due to its long computation time. A single run of SVM normally takes up to 24 hours, without the guarantee of returning any results. In view of this, the support vector machine (SVM) method was abandoned 原句是这个

首先，如果我是你，我会拆成两个句子。其次，我不是很明白这两句话之间的关系：并列还是因果？我估计是因果吧。再次，第二句主语太长。另外，some一词在这里不够specific。
修改意见如下：
These variables were treated as irregular compositional data. The transformation method was adopted for the data processing becauses it is specially suited for treating rounded or trace zeros in compositional data. 我的原句是这样的
The first expression of these three learning results can be illustrated by box ...

没明白。你是说我改后不符合你的原意？

另外，你第一句要说的是不是这个：
Both accuracy and minimazation of cost should be taken into account when evaluating the performance of the classifier.
LZ你在表意精准上还要下功夫。 没明白。你是说我改后不符合你的原意？

不是，我自己原来表达的意思有错误。大体说就是complexity 和 performance 不是对立关系，performance 蕴含complexity，还蕴含了别的东西 如accuracy。但是complexity越高，computation time 也就越长，所以有些方法必须放弃。 本帖最后由 Ravenheart 于 2010-9-16 20:42 编辑
accurary 和 minimazation 不是并列关系。他们是衡量算法好坏的一个标准，但是另一方面，我们必须考虑算法的complexity，应为complexity过高，会导致运算时间过长，导致方法在整体上的失败表现。基于此我们放弃了SVM的应用。
我觉得这样就对意思。
Both accuracy(or minimazation of cost) and complexity should be taken into account when evaluating the performance of the classifier 我想表达的意思是: 算法的复杂性和优异性是互相排斥的，两者只能取其一，牺牲一方换取另一方。在这个原则下，向量机方法因为它24小时的运算得不出结果而被抛弃。
============================================
A trade-off between the complexity and the performance of classifiers must be made.Since the vector machine method can not get any results in 24 Hours, it was abandoned. 2, 3
