This function describes the histogram distribution of unique values in an attribute, with respect to each class label of output attribute.

a good lecture for people who want to start working with embedded systems

引入了压缩因子，等改进优化算法的pso优化算法(An improved PSO algorithm is introduced, such as compressibility factor.)

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。(constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.)
