The book consists of three sections. The first, foundations, provides a tutorial overview of the principles underlying data mining algorithms and their application. The presentation emphasizes intuition rather than rigor. The second section, data mining algorithms, shows how algorithms are constructed to solve specific problems in a principled manner. The algorithms covered include trees and rules for classification and regression, association rules, belief networks, classical statistical models, nonlinear models such as neural networks, and local memory-based models. The third section shows how all of the preceding analysis fits together when applied to real-world data mining problems. Topics include the role of metadata, how to handle missing data, and data preprocessing.

此题目是通过键盘来实现密码输入是否正确,正确的时候数码管亮,否则发出报警声。 判断是按键还是干扰是非常有用的,它体现了一个系统的抗干扰能力。高低电平在瞬间的变换是很正常的,如果没有这条语句,系统很容易出错。 其中2秒是由定时器0来完成的。 在程序的定时器中断中,用switch代替了if else结构,使得程序的可读性大大增强。 TH0 = (65536-50000) / 256 TL0 = (65536-50000) 256 使得TH0 = 3CH, TL0 = B0H,由于该单片机的晶振为12MHz 因此定时时间就为0.05ms.在定时器中断服务程序中用FLASH计数,当计数达到40时正好是2秒。
