relative reduction meaning in English
相对压下量
Examples
- Finally experimental analysis of this algorithm shows it can obtain meaningful and small relative reduction
实践表明该方法能够获取有实际意义而又较小的约简。 - To facilitate comparisons between the trials , the relative ( proportional ) reduction of postoperative opioid administration and the relative reduction of postoperative pain were calculated on defined pain scales
为了便于在各试验间进行比较，通过确定的疼痛尺度来计算相对的（成比例的）术后阿片类药物需要的减少量以及术后疼痛的相对减少量。 - From the mapping relationship between information vector matrix and relative vectors , rough approximation , attribute relative reductions and selecting optimal attribute reductions set algorithms based on binary vector matrix were proposed
摘要根据向量矩阵与向量之间的映射关系，研究了基于二元向量矩阵算法的粗糙近似、属性约简以及最优属性约简集的获取。 - In this paper , we discuss the relationship between the condition attributes in terms of information entropy , and prove a useful inequality about relative reduction of attributes . a new significance of attributes in decision table is defined and is taken as a criterion to get a relative reduction
本文从信息熵的角度讨论条件属性之间的关系，证明了相对属性约简中的一个有用的不等式，并对决策表中属性的重要性给出一种新的度量。 - Secondly , we get two new reduction algorithms . the heuristic reduction algorithm based on the relative significance in information system is more natural and easier in computation and improves the reduction algorithm in speed . the conversional algorithm of the decision table based on the lower approximation reduction theory translate the relative reduction of the decision table into the reduction of the information system and offer a new method to find relative reduction of the decision table
信息系统中一种基于属性相对重要度的启发式约简算法较以往的算法意义更加直观，计算也更加简单，提高了约简算法的速度；基于下近似约简理论的决策表转化算法通过定义一个信息系统的下近似约简，将对决策表求相对约简转化为对信息系统求约简，得到了一种求决策表相对约简的新方法。
