学习July博文总结——支持向量机(SVM)的深入理解(下)

接上篇博文《学习July博文总结——支持向量机(SVM)的深入理解(上) 》; 三、证明SVM 凡是涉及到要证明的内容和理论,一般都不是怎么好惹的东西。绝大部分时候,看懂一个东西不难,但证明一个东西则需要点数学功底;进一步,证明一个东西也不是特别难,难的是从零开始发明创造这个东西的时候,则显艰难。因为任何时代,大部分人的研究所得都不过是基于前人的研究成果,前人所做的是开创性工作,而这往往是最艰难最有价值的,他们被称为真正的先驱。牛顿也曾说过,他不过是站在巨人的肩上。你,我则更是如此。正如陈希孺院士在他的著作

矢量符号架构作为纳米级硬件的计算框架

Abstract—This article reviews recent progress in the develop- ment of the computing framework Vector Symbolic Architectures(also known as Hyperdimensional Computing). This framework is well suited for implementation in stochastic, nanoscale hard- ware and it naturally expresses the types of cognitive operations required for Artificial Intelligence (AI). We demonstrate in this article that the ring-like algebraic structure of Vector Symbolic Architectures offers simple but powerful operations on high- dimensional vectors that can support all data structures and manipulations relevant in modern computing. In addition, we illustrate the distinguishing feature of Vector Symbolic Archi- tectures, “computing in superposition,” which sets it apart from conventional computing. This latter property opens the door to efficient solutions to the difficult combinatorial search problems inherent in AI applications. Vector Symbolic Architectures are Turing complete, as we show, and we see them acting as a framework for computing with distributed representations in myriad AI settings. This paper serves as a reference for computer architects by illustrating techniques and philosophy of VSAs for distributed computing and relevance to emerging computing hardware, such as neuromorphic computing.
