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.

It is recommended that the vehicle manufacturer andsupplier choose the test method, the environmental temperature and vibration parameters dependingon the specific mounting locationFollowing the expressions in MIL-STD please noticeC ISO 2012-All rights reservedIso16750-3:2012EWhen applied properly, the environmental management and engineering processes described in this partof Iso 16750 can be of enormous value in generating confidence in the environmental worthiness andoverall durability. However, it is important to recognize that there are limitations inherent in laboratorytesting that make itimperative to use proper caution and engineering judgement when extrapolating theselaboratory results to results that may be obtained under actual service conditions. In many cases, realworld environmental stresses (singularly orin combination cannot be duplicated practically or reliably intestlaboratories. Therefore, users of this part of Iso 16750 should not assume that a system or componentthat passes laboratory tests of this part of Iso 16750 would also pass field/ fleet verification trialsThe specified values are the best estimation one can get up to the moment when results frommeasurements in the car are received - but they do not replace a car measurement!The specified values apply to direct mounting in defined mounting locations. Using a bracket formounting can resultin higher or lower loads. If the device under test ( DUT)is used in the vehicle with abracket then all vibration and mechanical shock test shall be done with this bracketCarry out the vibration with the dut suitably mounted on a vibration table. The mounting method (sused shall be noted in the test report. Carry out the frequency variation by logarithmic sweeping of 0,5octave/minute for sinusoidal tests and the sinusoidal part of sine on random tests. The scope of therecommended vibration tests is to avoid malfunctions and breakage mainly due to fatigue in the fieldTesting for wear has special requirements and is not covered in this part of ISo 16750Loads outside of the designated test frequency ranges are to be considered separatelNOTE Deviations from the load on the DUT can result, should vibration testing be carried out according tothis part of Iso 16750 on a heavy and bulky dut, as mounting rigidity and dynamic reaction on the vibrator tableexcitation are different compared to the situation in the vehicle. This deviation can be minimized by applying theaverage control method(see Annex A)Application of the weighted average control method according to IEC 60068-2, 64 is to be agreed uponSubject the dut during the vibration test to the temperature cycle according to iEC 60068-2, 14, withelectric operation according to diagram 1. Alternatively, a test at constant temperature may be agreed onOperate the dutelectrically as indicatedin Figure l at Tmin(Short functional testafterthe dUT completelyreached Tmin). This functional test shall be as short as possible- only long enough to check the properperformance of the dUt. This minimizes self-heating of the dUT. Additional electrical operation of theDUT between 210 min and 410 min of the cycle (see Figure 1)Additional drying of test chamber air is not permittedIn the vehicle, vibration stress can occur together with extremely low or high temperatures; for thisreason, this interaction between mechanical and temperature stress is simulated in the test, too. afailure mechanism is, for example, a plastic part of a system/component, which mellows due to the hightemperature and cannot withstand the acceleration under this condition2o ISO 2012-All rights reservedIso16750-3:2012[EYmax20aburditt0100200300400500600yY temperature[°C]x time [ minIa Operating mode 3.2 according to ISo 16750-1.b Operating mode 2. 1 according to ISo 16750-1One cycleFigure 1-Temperature profile for the vibration testTable 1- Temperature versus time for the vibration testTimeTemperaturemin°C0206040150-4021020300max41048020See Is016750-44.1.2 Tests4.1.2.1 Test I- Passenger car, engine4.1.2.1.1 PurposeThis test checks the dUt for malfunctions and breakage caused by vibrationThe vibrations of a piston engine can be split up into two kinds: Sinusoidal vibration which results from theunbalanced mass forces in the cylinders and random noise due to all other vibration-schemes of an engine,C ISO 2012-All rights reserved3Iso16750-3:2012Ee.g. closing of valves.
