查询词典 birational invariant

Previous research has shown that smoking cessation enables better health as well lower medical care utilization. However, previous research usually treated smoking as a time invariant variable and hence can not determine the actual economic impact of smoking as time passes. In addition, previous research differs in research design and limited in duration of follow-up after smoking cessation. Hence it is necessary to conduct a study with longer period of follower-up.

虽然有研究证实戒菸可改善健康状况、减少医疗利用，然而上述研究有些系横断性，有些将吸菸状态设计为不随时间改变(time-invariant)的变项，无法呈现随时间改变的吸菸状态对医疗利用的影响；另外过去研究结果依研究设计、追踪年数不同而有所差异，若能追踪较长的时间，更可厘清戒菸时间与医疗利用间的关系。

This invariant relationship provides an exactly statistical interpretation forwhy the stochastic noise in gene expression should be measured by the normalizedvarianceσ

这个恒等式从统计上准确解释了，基因表达中要用标准化方差(σ2/ n 2，即方差除以期望的平方)作为基因表达随机噪声大小的测度而不是Fano factor的原因是，标准化方差揭示了基因表达中随机性和系统大小之间的本质联系。

As a result, it is convenient for the recognition system to use the simple linear classifier to segment the sample space, so that the accuracy and distortion invariant ability can be easily achieved. The classification structure of a bifurcating tree is utilized to decompose the classification problem of multi-classes to the multi-stage classification of two classes, which simplifies the design of the classifier, and improves the searching efficiency as well. A gray-scale analysis based method for extracting features from optical correlation result is proposed.

提出了二叉树鉴别分类方法，在使用同类图象的多个典型畸变样本训练识别系统的基础上，利用鉴别分析方法优化各类图象的特征向量在样本空间中的分布，不仅有利于同时提高系统的准确性和抗畸变能力，而且便于采用简单的线性分类器来划分样本空间；利用二叉树分类结构，将多类样本的分类问题分解为多级二类样本的分类问题，不仅简化了分类器的设计，而且提高了搜索效率。
