黄教授的极限学习机代码，结合他的论文看，很有用，希望有帮组(Extreme Learning Machine Code, very useful)

广义交义验证的去噪程序包，能够对一维和二维的信号及图像进行处理(PiefLab is a library of Matlab algorithms for wavelet noise reduction PiefLab has several routines for: 1) Wavelet transforms: fast and undecimated, (bi)orthogonal, 1D, 2D. Special attention was paid to fast implementation through Matlab blass routines and polyphase implementation of filter banks. )

包含了14段代码，主要是金融领域。包含了显性有限差分-期权定价、蒙特卡洛定价、风险中性期权定价等(Contains 14 sections of the code, mainly in the financial sector. Contains explicit finite difference- pricing, Monte Carlo pricing, risk-neutral pricing options)

AdaBoost, Adaptive Boosting, is a well-known meta machine learning algorithm that was proposed by Yoav Freund and Robert Schapire. In this project there two main files 1. ADABOOST_tr.m 2. ADABOOST_te.m to traing and test a user-coded learning (classification) algorithm with AdaBoost. A demo file (demo.m) is provided that demonstrates how these two files can be used with a classifier (basic threshold classifier) for two class classification problem.(AdaBoost, Adaptive Boosting, is a well-known meta machine learning algorithm that was proposed by Yoav Freund and Robert Schapire.
