Hibernate: A Developer s Notebook shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don t even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file. If you ve needed to add a database backend to your application, don t put it off. It s much more fun than it used to be, and Hibernate: A Developer s Notebook shows you why.

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.

This program is a new way to estimate the coherence function. It s based on the MVDR and is much more reliable than the classical Welch s method implemented in MATLAB. There are 2 programs: the main program called coherence_MVDR.m and and an example, called illustrate.m, that calls the main function to show how it works. There also included 2 papers that we published on this algorithm.

一个理想的系统应是R,S尽量小，而P,A尽可能大。而在一个实际系统中，S,R是相互制约的，拒识率R的提高总伴随着误识率S的下降，与此同时识别率A和识别精度P的提高。因此，在评价手写数字识别系统系统时，我们必须综合考虑这几个指标。另外，由于手写数字的书写风格、工整程度可以有相当大的差别，因此必须弄清一个指标在怎样的样本集合下获得的。

This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table.

C语言是在 70年代初问世的。一九七八年由美国电话电报公司(AT&T)贝尔实验室正式 发表了C 语言。同时由B.W.Kernighan和 D.M.Ritchit合著了著名的“THE C PROGRAMMING LANGUAGE”一书。通常简称为《K&R》，也有人称之为《K&R》标准。但是，在《K&R》中并 没有定义一个完整的标准C语言，后来由美国国家标准学会在此基础上制定了一个C 语言 标准，于一九八三年发表。通常称之为ANSI C。 当代最优秀的程序设计语言
