[机器学习]信息量、熵、交叉熵、KL散度，互信息

信息量I(x)=−logp(x) I(x) = - \log p(x)I(x)=−logp(x) 事件发生概率越低，信息量越大熵H(X)=−∑p(x)logp(x) H(X)=-\sum p(x) \log p(x)H(X)=−∑p(x)logp(x) 熵是在结果出来之前对可能产生的信息量求期望-考虑该随机变量的所有可能取值描述随机变量不确定程度，熵越大，信息量越大交叉熵H(p∣q)=−∑p(x)logq(x) H(p|q)=-\sum p(x) \log q(x)H(p∣q)=−∑p(x)logq(x) p为gt,q为预测分布 KL散度（相对熵）DKL(p∣∣q)=∑p(x)logp(x)q(x) D_{KL}(p||q)= \sum p(x) \log \frac {p(x)}{q(x)} DKL(p∣∣q)=∑p(x)logq(x)p(x) Kl散

[MySQL]MySQL备份与还原

备份单数据库mysqldump -u root -p dbname table1 table2 > backup.sql tabel1 table2 缺省则为备份整个数据库多数据库mysqldump -u root -p --databases dbname1 dbname2 > backup.sql全部数据库mysqldump -u root -p -all-databases > backup.sql还原mysql -u root -p dbname < backup.sql 当出现ERROR at line : Unknown command ‘\’’错误，是由字符集编码导致的，加上–default-character-set=utf8参数： mysql -u root -p --default-character-set=utf8 dbname < backup.sql

[JavaScript]Editor.md 图片复制粘贴拖拽js插件

IntroductionEditor.md富文本编辑器没有自带复制粘贴图片的功能，自己手写了个，支持复制粘贴、拖拽的方式插入编辑器中;并自动上传图片至博客后台的图床，省去了手动上传的麻烦。代码如下： function initPasteDragImg(Editor){ var doc = document.getElementById(Editor.id) doc.addEventListener('paste', function (event) { var items = (event.clipboardData || window.clipboardData).items; var file = null; if (items && items.length) { // 搜索剪切板items
