针对SVM法线特征筛选算法仅考虑法线对特征筛选的贡献,而忽略了特征分布对特征筛选的贡献的不足,在对SVM法线算法进行分析的基础上,基于特征在正、负例中出现概率的不同提出了加权SVM法线算法,该算法考虑到了法线和特征的分布.通过试验可以看出,在使用较小的特征空间时,与SVM法线算法和信息增益算法相比,加权SVM法线算法具有更好的特征筛选性能.(Normal feature selection for SVM algorithm only considered normal for the contribution of feature selection, to the neglect of the characteristics of the distribution of feature selection have contributed to the lack of normal SVM algorithm based on the analysis, based on the characteristics of the positive and negative cases emergence of a different probability-weighted normal SVM algorithm, which takes into account the distribution and characteristics of normal. through the test can be seen in the use of smaller feature space, the normal and the SVM algorithm and information gain algorithm, normal weighted SVM algorithm has better performance of feature selection.)

ALOHA-protocol-simulation
ALOHA协议的思想很简单,只要用户有数据要发送,就尽管让他们发送。当然,这样会产生冲突从而造成帧的破坏。但是,由于广播信道具有反馈性,因此发送方可以在发送数据的过程中进行冲突检测,将接收到的数据与缓冲区的数据进行比较,就可以知道数据帧是否遭到破坏。(ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.)
