物联网架构实例—解决Linux(Ubuntu)服务器最大TCP连接数限制

1.前言:在对物联网网关进行压测的时候,发现在腾讯云部署网关程序,设备接入数量只能达到4000多个长连接,之后就再也无法接入终端了。 之前在阿里云部署的时候明明可以到达2万左右,而且腾讯云的这个服务器比阿里云的硬件配置还要高上不少,不至于那么差,随后查阅大量资料终于完美解决。 2.解决步骤:2.1. ......

LightGCL Simple Yet Effective Graph Contrastive Learning For Recommendation论文阅读笔记

Abstract 目前的图对比学习方法都存在一些问题,它们要么对用户-项目交互图执行随机增强,要么依赖于基于启发式的增强技术(例如用户聚类)来生成对比视图。这些方法都不能很好的保留内在的语义结构,而且很容易受到噪声扰动的影响。所以我们提出了一个图对比学习范式LightGCL来减轻基于CL的推荐者的通 ......
