Fifty Years of Shannon Theory
应用背景
Fifty Years of Shannon Theory:
A brief chronicle is given of the historical development
of the central problems in the theory of fundamental limits
of data compression and reliable communication.
关键技术Shannon’s A mathematical theory of communication”published in July and October of 1948 is
the Magna Carta of the information age. Shannon’s discoveryof the fundamental laws of data compression and transmission marks the birth of Information Theory. A unifying theory with profound intersections with Probability, Statistics, Computer Science, and other fields, Information Theory continues to set the stage for the development of communications, data storage
and processing, and other information technologies.

在数据库中发现频繁模式和关联规则是数据挖掘领域的最基本、最重要的问题。大多数早期的研究采用了类似Apriori算法的产生候选级并测试迭代的途径代价是昂贵的,尤其是挖掘富模式和长模式时,Jiawei Han提出了一种新颖的数据结构FP_tree,及基于其上的FP_growth算法,主要用于有效的进行长模式与富模式的挖掘.本文在讨论了FP_growth算法的基础上,提出了用Visual C++实现该算法的方法,并编写了算法的程序。-found in the database model and the frequent association rules is the area of data mining the most fundamental and important issues. Most of the early studies used a similar Apriori algorithm for the selection of candidates and test-iterative way was costly, particularly mining the rich patterns and long model, Jiawei Han proposed a novel data structure FP_tree and on the basis of their FP_growth algorithm used effectively the model for long and rich patterns of excavation. This paper discussed the FP_growth algorithm on the basis of the Visual C of the algorithm, and the preparation procedure of the algorithm.
