SHA-1(Secure Hash algorIthm)是美国国家标准局(National Institute of Standard and Technology NIST)为了配合数位签章演算法(Digital Signature algorIthm DSA)的使用所发布的联邦资讯处理标准-FIPS PUB 180-1(Federal Information Processing Standard Publication 180-1),而SHA-1 则是SHA-1 (FIPS180)的改良版,现今与MD5 皆广被使用拿来做密码验证功能.其设计的方法是根据MD4,来对输入的资料讯息(Message)产生出一个160 位元的讯息摘要(Digest) ,对於资料安全性提供了有效的保障.

k-meansy算法源代码。This directory contains code implementing the K-means algorIthm. Source code may be found in KMEANS.CPP. Sample data isfound in KM2.DAT. The KMEANS program accepts input consisting of vectors and calculates the given number of cluster centers using the K-means algorIthm. Output is directed to the screen.

In this demo, I use the EM algorIthm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorIthm After downloading the file, type "tar -xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.
