:star: what is an r project include in r studio?An R project in RStudio is a self-contained directory that contains all the files and resources associated with a specific R project. This includes the R code files, data files, output files, and any additional packages or libraries needed for the project. RStudio automatically creates a new R project for each project you start, and allows you to easily switch between different projects within the RStudio interface. R projects in RStudio also provi ...

本文站在第三方的角度审视我在2022年的团队科研经历，一来是自省，二来是帮助更多同学更好的开始自己的科研生活。 科研工作是围绕一个科学问题展开的探索，只要是探索就有成功，有失败。而人工智能的科研探索，永远是以失败为主旋律。再详尽的计划，再强大的开发能力，都无法保证实验不出现问题。和数学条理清晰的证明不一样，人工智能深度学习的黑盒性质，使科研工作的展开注定磕磕绊绊。 :star:对科研成果的要求不同会议或期刊的收录倾向不同，例如CVPR喜欢新应用，NeurlPS喜欢理论的突破，AAAI相对就比较杂食，但对于一篇好文章的要求无非如下： 研究点新颖，要做到读者听上去就想要复现一下。 背景资料详实，需要找老前辈讨论。 论证的严谨，参考文献充足且逻辑自洽。 实验完备且充分，多角度多任务多场景（多数据集、多网络适配、多应用） 文章的行文规范且流畅，体现一个团队的积累。 :star:研究的三个板块对于一个课题组，如何进行人员的组织是一定要考虑的问题。任何一个错误的分工，或者一个模糊不清的角色定位都会造成课题推进的困难。接下来我们从三个主要的板块，展开讨论，科研团队中的大家如何扮演好自己的角 ...

:star:为什么需要文献管理工具？作为一名热爱学术的研究生，每天要阅读许多篇论文，每篇论文要经历繁琐的检索、下载、阅读的过程；在读了许多文献之后，想去回顾一下以前读过的文章，却发现面对着电脑中各种文献的文件夹，怎么也找不到想要找的文章了。这时候就需要一个文献管理工具，管理你的成千上百的文献，让你在写论文时很顺手地找到想要的文献。 :star:为什么选用Mendeley？:star:Mendeley的下载Mendeley有两个版本，官方页面上的是Mendeley Manager，但是异常难用。这里建议使用Mendeley Desktop配置本地论文仓库，也可以通过设置云端同步实现跨平台。 :star:Mendeley的基本使用:stars:使用界面 :stars:【重点】配置本地仓库 :stars:配置云端同步注：不推荐使用云端同步，第一Mendeley的空间有限，第二没有必要。如有需要，可以尝试Mendeley的第三方云端仓库同步。 :stars:Mendeley汉化可以直接下载绿色网传中文版，暂时没找到汉化补丁。 :star:Mendeley常用功能:stars:【重点】查询&#x ...

经常有小伙伴和我抱怨说拿不到计算资源，于是这不就来了吗。这是一个后台GPU排队脚本，主要是为了解决实验室中的显卡使用/占用问题。 ✨阅前须知 Talk is cheap, show me the code. 废话少说，直接给我代码！脚本代码跳转链接：脚本在这里 说给小白白的一些话： 本文只针对Nvidia显卡，依赖nvidia-smi查看显卡状态的命令。 本文提出的方法使用的是python作为终端脚本的启动器，默认python即可。 本文的方法是多显卡的贪心脚本，一个空窗期内有几张显卡就会用几张，小心使用。 本文方法无法实现显卡累加的操作，如果你想要那种闲下一张卡就抢过来的脚本，可以试试在本文的基础上进行修改。 ✨预备知识对理解GPU多卡排队脚本有帮助的内容： 在服务器上训练人工智能模型的时候往往是启动一个后台任务，启动后台任务的方法如下： 12#!/bin/bashnohup 【命令】 & 对于使用GPU的后台任务，如果没有好好的退出，会一直占用GPU资源。所以需要执行如下命令退出： 123456# 执行以下命令在全部线程中寻找你的后台线程：ps -ef ...

论文和自己的笔记不一样，和我成天写的博客类似，都是要提供最多的相关信息，便于读者理解。 只要有给小白讲明白这个点的想法，就不愁没得写 而且大概率会超页数。超了删，好删；少了加，就难喽 至少比你低一两个年级的同学能看懂或者不是很了解天体物理的量子物理教授能看懂 水论文小技巧1：谷歌翻译，中英或者英法互译，来回译上几轮，字数就多了 水论文小技巧2：分析文章观点展开逻辑，力求每一个观点的逻辑展开流程一致。之后只要多一环逻辑，全文每一块都可以多这一环 水论文小技巧3：大量公式，表格，图片 水论文小技巧4：观点前置，最后重复观点，强调重点
