I find myself coming back to the same few pictures when explaining basic machine learning concepts. Below is a list I find most illuminating. 1. Test and training error: Why lower training error is not always a good thing: ESL Figure 2.11. Test and t…
原文出处: 不会停的蜗牛    通过本篇文章可以对ML的常用算法有个常识性的认识,没有代码,没有复杂的理论推导,就是图解一下,知道这些算法是什么,它们是怎么应用的,例子主要是分类问题. 每个算法都看了好几个视频,挑出讲的最清晰明了有趣的,便于科普.以后有时间再对单个算法做深入地解析. 今天的算法如下: 决策树 随机森林算法 逻辑回归 SVM 朴素贝叶斯 K最近邻算法 K均值算法 Adaboost 算法 神经网络 马尔可夫 1. 决策树 根据一些 feature 进行分类,每个节点提一个问题,通过…
