ICA介紹課件。There has been a wide discussion about the application of Independence Component Analysis (ICA) in Signal Processing, Neural Computation and Finance, first introduced as a novel tool to separate blind sources in a mixed signal. The Basic idea of ICA is to reconstruct from observation sequences the hypothesized independent original sequences

This a naive implementation of BOOTP/TFTPBOOT, the protocols to use to bootstrap a computer through a TCP/IP network. The goal was to design a small footprint implementation to allow the code to be integrated into a monitor program stored in a ROM/FLASH, the footprint is about 7 KBytes for the test program. This code has not been yet tested in many environment. It should be seen at your starting point to integrate the network boot function to your board.

這是一個模擬第3類模式地震波的matlab腳本。 This a collection of Matlab scripts that solve the antiplane (mode III) earthquake dynamic problem with slip-weakening friction, on a 1D fault embedded in a 2D homogeneous elastic unbounded medium. The problem is formulated as a boundary integral equation and the elastodynamic kernels are analytically derived in the spectral domain (spatial wavenumber). The method is explained e.g. by Morrysey and Geubelle (1997), and has been improved and extensively used by Nadia Lapusta, Alain Cochard, etc.

FIST可堆疊文件系統(tǒng)，linux文件系統(tǒng)修改相關(guān)的開源軟件，使得對linux文件系統(tǒng)功能的改進(jìn)很簡單了 The FiST (File System Translator) system combines two methods to solve the above problems in a novel way: a set of stackable file system templates for each operating system, and a high-level language that can describe stackable file systems in a cross-platform portable fashion. Using FiST, stackable file systems need only be described once. FiST s code generation tool, fistgen, compiles a single file system description into loadable kernel modules for several operating systems (currently Solaris, Linux, and FreeBSD). The project demonstrates that with FiST, code size and development time are reduced significantly, while imposing a small performance overhead of only 1-2％. These benefits are achieved, as well as portability, without changing existing operating systems or file system.

Boosting is a meta-learning approach that aims at combining an ensemble of weak classifiers to form a strong classifier. Adaptive Boosting (Adaboost) implements this idea as a greedy search for a linear combination of classifiers by overweighting the examples that are misclassified by each classifier. icsiboost implements Adaboost over stumps (one-level decision trees) on discrete and continuous attributes (words and real values). See http://en.wikipedia.org/wiki/AdaBoost and the papers by Y. Freund and R. Schapire for more details [1]. This approach is one of most efficient and simple to combine continuous and nominal values. Our implementation is aimed at allowing training from millions of examples by hundreds of features in a reasonable time/memory.

A web crawler (also known as a web spider or web robot) is a program or automated script which browses the in a methodical, automated manner. Other less frequently used names for web crawlers are ants, automatic indexers, bots, and worms (Kobayashi and Takeda, 2000).來源。

古典密碼中，主要的思想為移位算法及置換算法。 1.移位密碼 密鑰K為整數(shù)，且取值空間為0到25；加密函數(shù)：x = x + k (mod 26)；解密函數(shù)：x = x - k (mod 26)。當(dāng)K=3時，為凱撒密碼。 2.仿射密碼 密鑰對由a、b組成，整數(shù)a滿足 gcd(a, 26) = 1，整數(shù)b的取值空間為0到25；加密函數(shù)：x = ax + b(mod 26)；解密函數(shù)：x = a*y - a*b (mod 26)。當(dāng)a=1,b=3時，為凱撒密碼。 3.維吉尼亞密碼 首先確定密鑰長度（本例中密鑰只采取個位數(shù)字，所以取決于輸入密鑰的長度），然后輸入滿足這個長度的向量；加密：取明文第一個字母并將之移k1位，這里k1=1,第二個字母移k2位，k2=2,一旦到了密鑰末尾，又從頭開始。 4.換位密碼 首先確定密鑰長度，輸入長度為5的0到4的整數(shù)序列，將明文分成每5個字母一組，每組字母按照密鑰進(jìn)行換位。

Thinking in C++ patiently and methodically explores the issues of when and how to use inlines, references, operator overloading, inheritance and dynamic objects, as well as advanced topics such as the proper use of templates, exceptions and multiple inheritance. The entire effort is woven in a fabric that includes Eckel’s own philosophy of object and program design. A must for every C++ developer’s bookshelf, Thinking in C++ is the one C++ book you must have if you’re doing serious development with C++.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa. For example, >> project.name = MyProject >> project.id = 1234 >> project.param.a = 3.1415 >> project.param.b = 42 becomes with str=xml_format(project, off ) "<project> <name>MyProject</name> <id>1234</id> <param> <a>3.1415</a> <b>42</b> </param> </project>" On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).
