TheCalculationandAnalysis
利用二维有限差分法对单脊波导TM模进行计算。通过调整网格数目观察计算结果的精度，可以设定出最优的网格数目，然后改变波导中脊的尺寸，观察最低两个TM模对应的截止频率的变化规律，最后给出对应的横截面电场、磁场分布图(The two-dimensional finite difference method to calculate the single-ridge waveguide TM mode. The optimal number of grid can be set by the accuracy of the adjustment of the calculation result of the grid number observed, and then change the size of the waveguide ridge observed the lowest two corresponding to the TM mode of the cutoff frequency of the variation, and finally to give the corresponding cross cross-section of the electric field, magnetic field maps)

gender-classification-experiments
这是用身高体重数据进行性别分类的实验。
用最小错误率贝叶斯分类器决策时，首先通过比较概率大小判断一个体重身高二维向量代表的人是男是女，然后再逐一与已知性别的数据比较，就可以得到错误率的统计。然后改变先验概率，重复上面的过程，观察数据结果的变化。
用最小风险贝叶斯分类器决策时，首先求出用最小错误率贝叶斯分类器得到的条件概率；然后根据人为给定的决策表，根据公式算出条件风险；然后逐一比较条件风险，找出使条件风险最小的决策（也就是分类）。最后用分类得到的结果逐一比较已经知道的原始数据，统计处错误率。
(This is the height and weight data for gender classification experiment.
With the minimum error rate Bayesian classifier decisions , first by comparing the probability of the size and weight to height to determine a person represented by two-dimensional vector is male or female , and then one by one with known gender data comparison, the statistical error rate can be . Then change the prior probability , repeat the above process , the results of the changes observed data .
Bayesian classifier with the minimum risk decision-making , first find the minimum error rate using Bayesian classifier to get the conditional probability then artificially given decision table , according to the formula to calculate conditional risk and then one by one more conditional risk , to find ambassador to the conditions of minimum risk decision making (ie classification) . Finally, the results obtained with the classification by-side comparison of the raw data have been aware of SD error rate .
