The aim of this paper is to suppress negative effect of noise on complex firing patterns of neurons and extract deterministic dynamical relationship underlying irregular interspike intervals. We first give a brief introduction to ISI data to be analyzed. Then a simple nonlinear noise reduction method based on chaos theory is presented. The method is finally used to analyze ISI data both from a theoretical model and experiments.

围绕如何来消除神经元峰峰间期序列中随机噪声影响从而提取出决定不规则性的确定性动力学关系这个问题，本文首先简要介绍峰峰间期序列样本的制备，然后着重讨论一个简单可行的混沌时间序列降噪方法的原理和算法实现，最终将该方法运用到神经元放电活动数值模拟和实验记录到的峰峰间期时间序列样本分析中。

The Mann-Whitney test is the nonparametric equivalent to the two-sample t-test and has little power with small sample sizes.

Mann-Whitney检验等同于参数检验中的两样本的t-检验，但对于同样的样本容量，检出力较小。

In the parameter estimation of the probability of default model,nonrandom sample selection will cause sample selec- tion bias and bring biased parameter estimation.

在贷款违约概率模型的参数估计过程中，样本选择的非随机性会产生样本选择性偏差，导致参数估计有偏。

In this algorithm, the variable vector corresponding to one arbitrary point in the pre-sampling set initializes the reduced basis space.

其基本做法就是，在参数空间预采样的基础上，从某个预采样样本点开始，把该点作为第一个样本点，把其对应的场变量向量作为第一个基向量对其他的预采样点进行减基近似。

In order to deal with the problem of face recognition with one sample per person, a method called sub-block Principal Component Analysis based on partitions of the sample is presented in this paper.

针对单样本人脸识别问题，本文提出了一种基于单样本切割的子模块主成分分析方法。

With this method, one-class classifier can be built when only the object of normal condition is available, and the abnormal condition can be distinguished from normal condition.

该方法在只有正常状态数据样本而无需故障样本的情况下可以建立起单值分类器，从而区分出机器的运行状态。

When outputting parameters were five grades,the correct rate (82.5%) in primitive sample of Ordered Logit model was higher than test sample of the Back-Propagation Network model one and model four (64.583% and 60.417%).

四、当输出变数为五个等级时，Ordered Logit模型原始样本分类正确率（82.5％）高於倒传递类神经网路模型一及模型四之测试样本（64.583％及60.417％）。

Essay 2: This paper examines the effect of obesity on earnings. It analyzes the 2001 National Health Interview Survey of Taiwan using the ordered probit model with sample selection in which earnings are defined as an ordered variable. We also transform the earnings from ordered variable to continuous variable and use the Heckman's two-stage model to estimate the effect.

第二篇：本文主要在探讨肥胖对收入的影响，并使用国家卫生研究院，民国90年国民健康访问调查资料(National Health Interview Survey， NHIS)来进行分析，并采两阶段的ordered probit with sample selection模型来进行估计，其中第一阶段为样本的就业选择问题，而第二阶段为样本在有就业的情况下，肥胖对劳动者收入的影响，而此收入为区间资料；另外，本文还将收入的区间资料转换为连续资料，以Heckman's two-stage的方法估计，并比较两估计结果。

Applying whitening process and Gram-Schimdt orthogonalization and orthogonal subspace projection, an optimal transformation matrix is designed to minimize the ratio of intra-class distance to inter-class distance while imposing the constraint that different class centers after transformation are along specifically directions that are orthogonal each other.

以线性变换后样本的类内距离与类间距离之比最小作为准则函数，同时加上约束条件使变换后的样本中心沿着特定的正交方向，通过白化变换、Gram-Schimdt正交化和正交子空间投影求解约束准则函数得到最优变换矩阵。
