摘要:随着机器学习和深度学习的热潮,各种图书层出不穷。然而多数是基础理论知识介绍,缺乏实现的深入理解。本系列文章是作者结合视频学习和书籍基础的笔记所得。本系列文章将采用理论结合实践方式编写。首先介绍机器学习和深度学习的范畴,然后介绍关于训练集、测试集等介绍。接着分别介绍机器学习常用算法,分别是监督学习之分类(决策树、临近取样、支持向量机、神经网络算法)监督学习之回归(线性回归、非线性回归)非监督学习(K-means聚类、Hierarchical聚类)。本文采用各个算法理论知识介绍,然后结合python具体实现源码和案例分析的方式)
1 安装Anaconda集成环境,Anaconda下载,安装下一步一路安装结束。(无需环境变量配置),配置完成后,查看是否成功。
2 打开cmd进入dos命令下,输入conda list 查看集成的python包
3 如果想添加新的python包,打开Anaconda官网:https://anaconda.org/search进行查找,比如想找到机器学习工具包scikit-learn
4 可以将Anaconda集成到PyDev、Pycharm、Eclipse、VS等编译环境即可,本文介绍集成到sublime中,首先进入官网下载sublime
5 直接进行下一步安装,一路到底。成功后显示:
6 安装Package Control: https://packagecontrol.io/installation
7 复制6中标记红色的文本内容(如下),然后右击红色小框,选择Console,将代码如下所示的放入文本框中,按Enter即可。
import urllib.request,os,hashlib; h = 'df21e130d211cfc94d9b0905775a7c0f' + '1e3d39e33b79698005270310898eea76'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( 'http://packagecontrol.io/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)
8 完成7步骤后,按ctrl+shift+p打开如下窗口,并点击标红处,然后对应插件的下载和安装
9 下图输入框安装如下插件:
ConvertToUTF8 :解决中文问题
Colorsublime - Themes:Colorsublime 的主题集合
SublimeREPL:Python运行

Alignment:自动对齐,ctrl+alt+a
Anaconda:python插件集合,禁用PEP8提示:Sublime > Preferences > Package Settings > Anaconda > Settings – User: {"anaconda_linting": false}
SublimeLinter-pep8
根据需要自行添加插件
10 主题配置:打开 Preferences > Settings (若报错,注意下图红色标记内容color_scheme整行替换)

"command": "run_existing_window_command",
"args": {
"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"
}
}, {
"keys": ["f6"],
"caption": "SublimeREPL: Python",
"command": "run_existing_window_command",
"args": {
"id": "repl_python",
"file": "config/Python/Main.sublime-menu"
}
},{
"keys": ["ctrl+d"],
"command":"run_macro_file",
"args": {"file":"res://Packages/Default/Delete Line.sublime-macro"}
}
]
12 分屏:ctrl+shift+1单屏,ctrl+shift+2左右分屏,ctrl+shift+8上下分屏,
13 如果没有自动提示,可以如下配置,打开Preferences >Package Settings >Anaconda >Setting Default输入:Administrator改为你计算机的名字
"python_interpreter": "C:/Users/Administrator/Anaconda3/python.exe"
打开Preferences >Package Settings >Anaconda >Setting Users输入:Administrator改为你计算机的名字
{
"python_interpreter":"C:/Users/Administrator/Anaconda3/python.exe",
"suppress_word_completions":true,
"suppress_explicit_completions":true,
"complete_parameter":true,
}
到此,完成全部配置工作

sublime配置php
1 下载并安装WampServer集成环境
2 按win+R输入sysdm.cpl打开系统属性,配置环境变量C:\wamp\bin\php\php5.5.12
3 cmd命令窗体,输入命令php -h查看是否会提示php的命令使用方法
4 创建php编译系统,运行Sublime Text,选择Tool——>Build System——>New Build System,在新弹出的窗体中,
把默认内容
({ "shell_cmd": "make"}替换成
{ "cmd": ["php", "$file"], "file_regex": "php$", "selector": "source.php" }
保存在默认的目录下即可,注意修改文件名为 php.sublime-build 。
重启sublime text,就可以用Ctrl+B来编译.php文件了;
