模式识别——基于ID3算法的三次改进
ID3算法是决策树的鼻祖，最早于1986年由Quinlan提出，全称是Iterative Dichotomiser 3 [1]。在这篇课程报告中，我将对经典的ID3做出三次改进：1.把 info gain 改进为 gain ratio；2. 把简单投票的过程改进为朴素贝叶斯的方法；3. 将许多颗ID3决策树打造成随机森林。本人将在Weka平台进行二次开发，并且用Weka-Experiment做大量实验，和其它著名的算法进行比较，最后做出综述。项目的源代码开源在本人的GitHub主页上。未来工作有以下几点:是那么容易就可以随机出来的1.在 Improvement Two中,3树的生长的深度限3.可以把这三种改进方法糅合在一起,看看三种制在多少,可以进行进一步的研究改进组合在一起,能不能产生性能更加的算法2.在 Improvement Three中,本人费劲心思写出来4.上述所有方法都是基于属性为 nominal的数据的“随机森林”,正确率反而比D3更差。虽然集,可以进一步研究属性为 numerical,甚至是很使我伤心,但是我在写代码、调试代码、还有两者混合的数据集。思考的过程中有了不少长进。看来随机森林不L己ta3et(1 caitao.I(2) caita (3 caita (4 caita (5) trees (6)treesca置,色va1 eatlon(100)B9.19|81.36*92.85V78.日9*94.43W93.40Vweather. symbolic100)79.00|56.507s.0079.57.506,50{v!/*)|(0/1/1)(1/1/0(011/1)(1/1/0)(1/1/0Re1)caia。,工3"-26936786470963225612) CaILE。 gainRatio.工D311-2693678647096322561(3 caitao naiveBayes.

基于MATLAB/Simulink的双闭环直流调速系统设计
根据设计多环控制系统的一般原则进行系统设计：从内环开始，一环一环地逐步向外扩展。先从电流环入手，首先设计好电流调节器，然后把整个电流环看做转速调节系统的一个环节，再设计转速调节器。稳态指标的要求：系统无静差。动态指标的要求：空载启动到额定转速时的转速超调量σn≤10%，电流超调量σi≤5%。
