Voting classifier 多种分类器分别训练,然后分别对输入(新数据)预测/分类,各个分类器的结果视为投票,投出最终结果: 训练: 投票: 为什么三个臭皮匠顶一个诸葛亮.通过大数定律直观地解释: 一个硬币P(H)=0.51.大数定律保证抛硬币很多次之后,平均得到的正面频数接近\(0.51 \times N\),并且N越大,越接近.那么换个角度,N表示同时掷硬币的人数,即为这边的N个臭皮匠,他们的结果合到一起就得到的是接近真实结果的值. 进一步根据中心极限定理,即二项分布以正态分布为其极…

之前摸爬滚打总是各种坑,今天参考这篇文章终于解决了,甚是鸡冻\(≧▽≦)/,电脑不知道怎么的,安装不了16.04,就安装15.10再升级到16.04 requirements: Ubuntu 16.04 python 2.7 Flask tensorflow GPU 版本 安装nvidia driver 经过不断踩坑的安装,终于google到了靠谱的方法,首先检查你的NVIDIA VGA card model sudo lshw -numeric -C display 可以看到你的显卡信息,比如…
