朴素贝叶斯分类器一阶扩展的注记

众多研究者致力于将朴素贝叶斯方法与原有的ILP系统结合，形成各种各样的多关系朴素贝叶斯分类器(MRNBC)。该文提出形成朴素贝叶斯分类器的一阶扩展的一般方法。现实中关系数据库广泛存在，可以直接作用于数据库表，而无须转换表示形式的MRNBC则是研究的重点，该方法主要基于关系数据库理论，分析了进行一阶扩展的关键问题。

Notes on First-order Upgrading to Naïve Bayesian Classifier

Digital proxy multi-signature scheme and blind signature are very suitable for electronic commerce and payment. Based on the Schnorr signature and Chaum blind signature scheme, this paper presents an efficient proxy blind multi-signature scheme, which satisfies the security properties of both the blind signature scheme and the proxy multi-signature scheme. This scheme has advantages such as the low computation load, high efficiency and security, and the length of signature does not increase when the new original signers join in. It is very important in an electronic cash and electronic vote system.
