DBSCAN算法
% Function: [class,type]=dbscan(x,k,Eps)
% -------------------------------------------------------------------------
% Aim:
% Clustering the data with Density-Based Scan Algorithm with Noise (DBSCAN)
% -------------------------------------------------------------------------
% Input:
% x - data set (m,n); m-objects, n-variables
% k - number of objects in a neighborhood of an object
% (minimal number of objects considered as a cluster)
% Eps - neighborhood radius, if not known avoid this parameter or put []
% -------------------------------------------------------------------------
% Output:
% class - vector specifying assignment of the i-th object to certain
% cluster (m,1)
% type - vector specifying type of the i-th object
% (core: 1, border: 0, outlier: -1)

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.
