一.机器学习算法分类: 监督学习:提供数据和数据分类标签.--分类.回归 非监督学习:只提供数据,不提供标签. 半监督学习 强化学习:尝试各种手段,自己去适应环境和规则.总结经验利用反馈,不断提高算法质量 遗传算法:淘汰弱者,留下强者,进行繁衍和变异穿产生更好的算法. 二.选择机器学习算法和数据集 sklearn中有很多真实的数据集可以引入,也可以根据自己的需求自动生成多种数据集.对于数据集可以对其进行归一化处理. sklearn中的有着多种多样的算法,每一种算法都有其适用的场合.不同的属性和功…

原文:thinkphp学习笔记9-自动加载 1.命名空间自动加载 在3.2版本中不需要手动加载类库文件,可以很方便的完成自动加载. 系统可以根据类的命名空间自动定位到类库文件,例如定义了一个类Org\Util\Auth类: namespace Org\Util; class Auth { } 保存到ThinkPHP/Library/Org/Util/Auth.class.php 这样我们就可以直接实例化了, new \Org\Util\Auth(); 实例化之后系统会自动加载 ThinkPHP/…
