摘要:为提高密码的抗攻击性,利用超混沌系统随机性好!可确定再生,且密钥空间较大的特性,提出了一种基于四维连续超混沌系统和扩展映射的实时视频流加密算法"(Abstract: In order to improve the password anti-aggressive use of system randomness hyperchaos good! Regeneration can be identified, and key characteristics of the larger space, a row based on four-dimensional hyperchaotic system and expansion of mapping real-time video stream encryption algorithm )

CARS变量选择方法能够在一定程度上克服变量选择中的组合爆炸问题，筛选出优化的变量子集，提高模型的预测能力( Competitive Adaptive Reweighted Sampling method for variable selection.)

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

Adaboost是一种迭代算法,其核心思想是针对同一个训练集训练不同的分类器(弱分类器),然后把这些弱分类器集合起来,构成一个更强的最终分类器(强分类器)。(Adaboost is an iterative algorithm, the core idea is the same training set for different classifiers (weak classifiers), then these weak classifiers together to form a stronger final classifier (strong classifier).)
