中文说明：包括最小二乘法、SVM、神经网络、1_k近邻法,cordic算法的matlab仿真，主要是基于mtlab的程序，是学习PCA特征提取的很好的学习资料，独立成分分析算法降低原始数据噪声，利用贝叶斯原理估计混合logit模型的参数。
English Description：
Including the least squares method, SVM, neural network, 1 K nearest neighbor method, CORDIC algorithm matlab simulation, mainly based on MTLAB procedures, is learning PCA feature extraction of very good learning materials, independent component analysis algorithm using Bayesian principle to estimate a mixed logit model parameter so as to reduce the raw data noise.
