DES( Data Encryption Standard)算法，于1977年得到美國政府的正式許可，是一種用56位密鑰來加密64位數(shù)據(jù)的方法。 idea是International Data Encryption Algorithm 的縮寫,是1990年由瑞士聯(lián)邦技術(shù)學(xué)院來學(xué)嘉X.J.Lai 和Massey提出的建議標準算法稱作PES( Proposed Encryption Standard) 。Lai 和Massey 在1992 年進行了改進強化了抗差分分析的能力改稱為idea 它也是對64bit大小的數(shù)據(jù)塊加密的分組加密算法密鑰長度為128位它基于“相異代數(shù)群上的混合運算”設(shè)計思想算法用硬件和軟件實現(xiàn)都很容易且比DES在實現(xiàn)上快的多。idea自問世以來，已經(jīng)經(jīng)歷了大量的詳細審查，對密碼分析具有很強的抵抗能力，在多種商業(yè)產(chǎn)品中被使用。

In 1960, R.E. Kalman published his famous paper describing a recursive solution to the discretedata linear filtering problem [Kalman60]. Since that time, due in large part to advances in digital computing, the Kalman filter has been the subject of extensive research and application, particularly in the area of autonomous or assisted navigation. A very “friendly” introduction to the general idea of the Kalman filter can be found in Chapter 1 of [Maybeck79], while a more complete introductory discussion can be found in [Sorenson70], which also contains some interesting historical narrative.

This document contains a general overview in the first few sections as well as a more detailed reference in later sections for SVMpython. If you re already familiar with SVMpython, it s possible to get a pretty good idea of how to use the package merely by browsing through svmstruct.py and multiclass.py. This document provides a more in depth view of how to use the package. Note that this is not a conversion of SVMstruct to Python. It is merely an embedding of Python in existing C code. All code other than the user implemented API functions is still in C, including optimization.

The need for accurate monitoring and analysis of sequential data arises in many scientic, industrial and nancial problems. Although the Kalman lter is effective in the linear-Gaussian case, new methods of dealing with sequential data are required with non-standard models. Recently, there has been renewed interest in simulation-based techniques. The basic idea behind these techniques is that the current state of knowledge is encapsulated in a representative sample from the appropriate posterior distribution. As time goes on, the sample evolves and adapts recursively in accordance with newly acquired data. We give a critical review of recent developments, by reference to oil well monitoring, ion channel monitoring and tracking problems, and propose some alternative algorithms that avoid the weaknesses of the current methods.

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
