今天看到一篇1988年的老文章谈到了训练一个简单网络是NPC问题[1].也就是下面的网络结构,在线性激活函数下,如果要找到参数使得输入数据的标签估计准确,这个问题是一个NPC问题.这个文章的意义在于宣判了找简单的神经网络来降低计算难度是行不通的,同时找多项式内求解的算法也不用再考虑了. 站在时代的背景上,这篇文章反应了算力不足时期神经网络的尴尬位置,告诉我们算力设备是搞神经网络不可缺少的资源. [1] A. Blum and R. L. Rivest, "Training a 3-Node Ne…

作者简介: 吴天龙  香侬科技researcher 公众号(suanfarensheng) 导言 图(graph)是一个非常常用的数据结构,现实世界中很多很多任务可以描述为图问题,比如社交网络,蛋白体结构,交通路网数据,以及很火的知识图谱等,甚至规则网格结构数据(如图像,视频等)也是图数据的一种特殊形式,因此图是一个很值得研究的领域. 针对graph的研究可以分为三类: 1.经典的graph算法,如生成树算法,最短路径算法,复杂一点的二分图匹配,费用流问题等等: 2.概率图模型,将条件概率表达为…
