For most circumstances, redundant phenomenon is really a kind of negative one of language expression. 从大多数情况看,赘余现象确实是语言表达的一种消极现象。
Intron is a redundant expression for individual and attached to its algorithm tree, which makes the individual swelling but has no effect to the final output. 它们是冗余的表达式,附加在算法树上,使个体变得臃肿,但对实际的输出结果没有影响。
Aiming at the existence of redundant nodes, this paper put forward the minimization of path expression basing on the implication theories, which reduces the size of patterns tree and increases matching efficiency. 对于查询路径表达式存在的冗余结点问题,根据蕴含理论将其最小化,减小路径表达式所对应的模式树的规模,以提高匹配效率。
Under the premise of not influencing the accuracy of Text Categorization, it can cancel the redundant information, get obviously categorization rules, and reduce the knowledge expression space. 它在不影响分类精度的前提下通过信息约简,去掉冗余信息,得到显式的文本分类规则,简化信息的表达空间维度。
However, there are large number of redundant gene expression data, which constrains to obtain valuable classification information. 但是基因数据中往往有大量冗余的无关基因信息,这些制约了从基因数据中得到有价值的分类信息。
