拿到一个uboot 后,我都想添加一个属于自己的board文件以及include/configs/*.h 文件. 如何添加这个些文件,今天来记录一下. 复制一份你所参考的板级文件,比如说board/vscom/baltos/ 复制为board/sbc7109 文件夹 修改board/sbc7109/Kconfig 里面的内容 if TARGET_AM335X_SBC7109 // 这个是等下make menuconfig 指定的一个宏 config SYS_BOARD //指定你的board 文

1.前言 Linux系统的启动需要一个bootloader程序,该bootloader程序会先初始化DDR等外设,然后将Linux内核从flash中拷贝到DDR中,最后启动Linux内核,uboot的全称为Universal Boot Loader,Linux系统中常用的bootloader就是uboot,接下来,将会进行简单的uboot启动流程分析,uboot的源码为uboot-imx-rel_imx_4.15_2.1.0. 2.uboot入口 在分析之前,需要对整个uboot工程进行编译,生

这篇文章有点深度,可能需要一些Lucene或者全文检索的背景.由于我也很久没有看过Lucene了,有些地方理解的不对还请多多指正. 更多内容还请参考整理的ELK教程 关于Term Vectors 额,对于这个专业词汇,暂且就叫做词条向量吧,因为实在想不出什么标准的翻译.说的土一点,也可以理解为关于词的一些统计信息.再说的通俗点,如果想进行全文检索,即从一个词搜索与它相关的文档,总得有个什么记录的信息吧!这就是Term Vectors. 为了不干扰正常的理解,后续就都直接称呼英文的名字吧!免得误导

I. 复习word2vec的核心思路 1. Skip-gram 模型示意图: 2.word vectors的随机梯度 假设语料库中有这样一行句子: I love deep learning and NLP 中心词为deep,那么在计算梯度的时候则可以得到如下的梯度向量. 可以很明显地看到该向量非常稀疏.常见的解决办法有两种:一是使用稀疏矩阵更新运算来更新矩阵\(U,V\)的特定的列向量.二是使用哈希来更新,即key为word string,value是对应的列向量. II. 近似 1. 负采样
