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…

一.MPI为何物? 初步了解:MPI集群环境搭建 二.重新认识Spark 链接:https://www.zhihu.com/question/48743915/answer/115738668 马铁大神的phd thesis 总结里面说了一句话 大概意思是说 单纯的如果使用mpi 来实现一个算法 比spark 快五六倍是很正常的 但是spark 是一个 general 的 data flow 处理框架 就是可以在数据的生命周期里面 可以使用spark 之上的具体实现来处理数据 ml 只是一部分而…

Machine Learning for Developers Most developers these days have heard of machine learning, but when trying to find an 'easy' way into this technique, most people find themselves getting scared off by the abstractness of the concept of Machine Learnin…

About me In my spare time, I love learning new technologies and going to hackathons. Our hackathon project Pantrylogs using Artificial Intelligence was selected as one of the 10 Microsoft Imagine Cup UK finalists. I’m interested in learning more abou…

the main steps: 1. look at the big picture 2. get the data 3. discover and visualize the data to gain insights 4. prepare the data for machine learning algorithms 5. select a model and train it 6. fine-tune your model 7. present your solution 8. laun…

A Gentle Guide to Machine Learning Machine Learning is a subfield within Artificial Intelligence that builds algorithms that allow computers to learn to perform tasks from data instead of being explicitly programmed. Got it? We can make machines lear…
