We are now going to consider a rather different approach to machine learning, starting with one of the most common and powerful data structures in the whole of computer science: the binary tree. The computational cost of making the tree is fairly low…

Seven Python Tools All Data Scientists Should Know How to Use If you’re an aspiring data scientist, you’re inquisitive – always exploring, learning, and asking questions. Online tutorials and videos can help you prepare you for your first role, but t…

Machine Learning Methods: Decision trees and forests This post contains our crib notes on the basics of decision trees and forests. We first discuss the construction of individual trees, and then introduce random and boosted forests. We also discuss…

决策树在商品购买能力预测案例中的算法实现 作者:白宁超 2016年12月24日22:05:42 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(…

昨天总结了深度学习的资料,今天把机器学习的资料也总结一下(友情提示:有些网站需要"科学上网"^_^) 推荐几本好书: 1.Pattern Recognition and Machine Learning (by Hastie, Tibshirani, and Friedman's ) 2.Elements of Statistical Learning(by Bishop's) 这两本是英文的,但是非常全,第一本需要有一定的数学基础,第可以先看第二本.如果看英文觉得吃力,推荐看一下下面…

1 什么是随机森林? 作为新兴起的.高度灵活的一种机器学习算法,随机森林(Random Forest,简称RF)拥有广泛的应用前景,从市场营销到医疗保健保险,既可以用来做市场营销模拟的建模,统计客户来源,保留和流失,也可用来预测疾病的风险和病患者的易感性.最初,我是在参加校外竞赛时接触到随机森林算法的.最近几年的国内外大赛,包括2013年百度校园电影推荐系统大赛.2014年阿里巴巴天池大数据竞赛以及Kaggle数据科学竞赛,参赛者对随机森林的使用占有相当高的比例.此外,据我的个人了解来看,一大部…

Abstract - Undersampling is a popular method in dealing with class-imbalance problems, which uses only a subset of the majority class and thus is very efficient. The main deficiency is that many majority class examples are ignored. We propose two alg…
