Random Decision Forest

鉴于目前已经在两篇文章里面看到了 random forest 概念:
1)Real Time Action Recognition Using Histograms of Depth Gradients and Random Decision Forests
2)Efficient human pose estimation from single depth images (kinect 工作原理)
决定认真的学习一下Random Forest的概念,并知道如何使用
一个比较好的有关random forest 形象的解释见下链接:
https://www.youtube.com/watch?v=loNcrMjYh64
Step1: suppose we have a matrix of training samples
Step 2: Create several random subsets and generate several random decision trees, and then we will get a random forest!
Step 3: Use each random decision tree to predict the label of the test sample, and finally choose the most reliable one
更理论性的知识以及实际使用以后再补
