This article introduces the networking part of Elasticsearch. We look at the network topology of an Elasticsearch cluster, which connections are established between which nodes and how the different Java clients works. Finally, we look a bit closer o…

目录 01 Introduction Bridging this gap between AI and humans is an important direction. FSL can also help relieve the burden of collecting large-scale supervised data. Driven by the academic goal for AI to approach humans and the industrial demand for…

一.PGM用来做什么 1.  医学诊断:从各种病症分析病人得了什么病,该用什么手段治疗 2.  图像分割:从一张百万像素级的图片中分析每个像素点对应的是什么东西 两个共同点:(1)有非常多不同的输入变量:(2)对于算法而言,结果都是不确定的 二.PGM各代表什么 1.  Models 2.  Probabilistic (1)概率:设计model即是为了分析一些不确定的东西(uncertainty) (2)Uncertainty的来源: (3)概率在模型表达上的优势 3.  Graphical…

一.什么是factors? 类似于function,将一个自变量空间投影到新空间.这个自变量空间叫做scope. 二.例子 如概率论中的联合分布,就是将不同变量值的组合映射到一个概率,概率和为1. 三.几种操作(factor operation)的介绍 1.乘积 2.边缘化 3.缩减 四.总结(为何引入factor?) 1.对于定义高维空间的分布具有关键意义: 2.包括了概率分布的基本操作.…

ElasticSearch 2 (11) - 节点调优(ElasticSearch性能) 摘要 一个ElasticSearch集群需要多少个节点很难用一种明确的方式回答,但是,我们可以将问题细化成一下几个,以便帮助我们更好的了解,如何去设计ElasticSearch节点的数目: 打算处理多少数据? 打算处理多少搜索请求? 请求的复杂度是怎样? 每个节点有多少资源数? 打算建立多少索引,支持多少应用? 版本 elasticsearch版本: elasticsearch-2.x 内容 一个集群解决所…
