Character-Recognition(Lib-SVM)
支持向量机的研究现已成为机器学习领域中的研究热点,其理论基础是Vapnik[3]等提出的统计学习理论。统计学习理论采用结构风险最小化准则,在最小化样本点误差的同时,缩小模型泛化误差的上界,即最小化模型的结构风险,从而提高了模型的泛化能力,这一优点在小样本学习中更为突出。SVM理论正是在这一基础上发展而来的,经过十几年的研究和发展,已开始逐步应用于一些领域。在解决小样本、非线性及高维模式识别问题中表现出许多特有的优势,已经在模式识别、函数逼近和概率密度估计等方面取得了良好的效果。( Support Vector Machine (SVM) is a new machine learning technique in recent years developed based on statistical learning theory (SLT). It wins popularity due to many attractive features and emphatically performance in the fields of nonlinear and high dimensional pattern recognition. The theory and algorithm of SVC is studied at first, then, simulation is to recognize handwritten numeral with the Lib-SVM toolbox. At last, we study the result, which shows that the SVC can do the classification problem with good performance, shorter operation time and is more suitable for real-time implementation.)

Scale-free-network
Albert-László Barabási与Réka Albert在1999年的论文中提出了一个模型来解释复杂网络的无标度特性,称为BA模型。这个模型基于两个假设:
增长模式:不少现实网络是不断扩大不断增长而来的,例如互联网中新网页的诞生,人际网络中新朋友的加入,新的论文的发表,航空网络中新机场的建造等等。
优先连接模式:新的节点在加入时会倾向于与有更多连接的节点相连,例如新网页一般会有到知名的网络站点的连接,新加入社群的人会想与社群中的知名人士结识,新的论文倾向于引用已被广泛引用的著名文献,新机场会优先考虑建立与大机场之间的航线等等。
(Albert-László Barabási with Réka Albert in the 1999 paper proposed a model to explain the complex networks of scale-free property, known as the BA model. This model is based on two assumptions:
Growth pattern: a lot of real network is expanding growing from, for example, the birth of the Internet BEIJING, page, new friends to join the network of people, a new paper published aviation network in the new airport construction and so on.
Priority connection mode: a new node upon accession will tend to connect to the node connected to, for example, a new page will generally have a connection to the well-known networking sites, and the new Community will want with the community s well-known get to know the new paper preference is to use well-known literature has been widely cited, the new airport will give priority to create and airport routes.)
