  • 清华大学模式识别第二次大作业
    1. 仍然使用第一次作业中收集的数据作为训练集(注意:不得超过20+20 例样本),采用身高和体重为特征进行性别分类,训练SVM 分类器,在测试数据dataset1.txt 上测试分类效果。SVM 中分别使用线性核和高斯核,参数自己确定。2. 使用一个较大的数据集(dataset2.txt)作训练样本,采用身高和体重为特征进行性别分类,在正态分布假设下估计概率密度,建立最小错误率贝叶斯分类器,写出得到的决策规则;把分类器应用到dataset1.txt 上,计算测试错误率。(自行决定采用什么先验概率。)3. 将样本和两次作业中得到的多个分类面画到由身高和体重组成的二维平面上,尝

  • 三维点云数据的预处理研究
    本文 重 点 研究点云数据编码压缩方法和邻域搜索算法。(1)、根据点云数据的特点,建立八叉树模型,对原始数据进行坐标变换,映射到正整数空间,在此基础上计算数据的Morton码。对Morton码排序、求差,统计码长,提出了一种改进Morton码的方法。该方法提高了Morton编码的连续性,降低了八叉树的深度,减少了数据存储量。并可应用三维行程编码等方法进一步压缩优化后的Morton码。试验结果证明了算法的有效性。(2)、把应用在四叉树模型的编码邻域算法推广到空间的八又树模型,并与栅格邻域搜索算法做定性比较。此外,还简单介绍了Delaunay三角划分方法及其优化准则,Hoppe的三角网格重构算法。

  • 微分方的平衡点及稳定性分析
    对于微分方程平衡点稳定性的分析,有助于对混沌系统微分方程组的平衡点的判断。保山学院学报2010第2期接法需要求出系统的解析解,对于一些简单方程阵为:/(0-2|,p=4,g=4,故P00是系统的可能很容易求出,而对于一些复杂的方程(比如例稳定的平衡点2),我们是借助了数学软件求出的方程的通解;而在点21,0)处,系统的线性近似方程的系数矩直接法不用求方程的解就可以讨论平衡点的稳定性。我们在数学建模的过程中,有些系统不用求解阵为(0-2|,p=4,q=4,故P21,0是系统的方程,只需要研究平衡点的稳定状态所以用直接稳定的平衡点;法分析平衡点的稳定性是非常有用的。在点P处,系统的线性近似方程的系数矩10阵为A302|10=19=2,故P(2,是系统参考文:[冯杰,黄力伟等.数学建模原理与案例M北京科学的不稳定的平衡点;出版社,2007,1[2]张锦炎,冯贝叶.常微分方程几何理论与分支问题M3.结论北京:北京大学出版社,2005,8从上面的分析和例子可以看出,平衡点的稳3]阳明盛.
