训练错误率和交叉验证错误率相等，在样本比较大时，这个结果是可以预期的；训练错误率一般低于测试错误率，但是当样本数据比较少时，实验也出现了意外，样本多的那组测试错误率比样本少的训练错误率还要小；在本实验中，同组数据的交叉验证错误率比独立测试错误率高，这个反常现象是因为样本的原因所致，交叉验证的样本小，而独立测试时所用训练样本数目大，因而出现这种情况。分类线上，fisher准则是一条直线，而贝叶斯分类器实际上是一个类似椭圆的封闭曲线；很明显，贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)

The Matlab Code present the development of an intelligent PID controller using Cultural Artificial Bee Colony Algorithm CABCA. The Normative and situational Knowledge in cultural algorithm were first used to guide the evolution and direction of ABC. thereafter the develop controller was used in the position control of DC motor.

This is a program for extracting objects from an image. Written for vehicle number plate segmentation and extraction. Authors : Jeny Rajan, Chandrashekar P S. U can use attached test image for testing input - give the image file name as input. eg :- car3.jpg(This is a program for extracting objects from an image.

数字图像处理中matlab环境先的几个实用的滤波函数(With the aid of examples such as histogram equalization analysis and spatial filtering, this article explains the application of matlab in image processing.)

UWB-Run from editor debug(F5)-PPM(pulse position modulation) of UWB monocycle and doublet waveforms. This m file plots the time and frequency waveforms for PPM 1st and 2nd derivative equations used in UWB system analysis. Fudge factors are required to correct for inaccuracies in the 1st and 2nd derivative equations. Tail to tail on the time wave forms must be considered as the actual pulse width.
