Friendly Reminder FIRST PROJECT DEADLINE: 10.27 11:30pm!!! Tree based packages rpart party randomForest ranger We will use the famous Dataset iris as example, first take a look at dataset iris. We want to predict the Species based on each observation’s covarates head(iris) ## Sepal.Length Sepal.Width Petal.Length Petal.Width Species ## 1 5.1 3.5 1.4 0.2 setosa ## 2 4.9 3.0 1.4 0.2 setosa ## 3 4.7 3.2 1.
My name is Peigen Zhou (周培根). This is my personal website for blogging and some information.
In my name, “培根” the direct translation of 培根 is Bacon. But “培” in Chinese means “cultivate”, “根” means “root”. My grandpa gives me the name, hope I can be a man who has the solid base like a tree.
- GUIDE is a multi-purpose machine learning algorithm for constructing classification and regression trees.
- Emacs is my favoriate editor, which has over 2,000 built-in commands and allows the user to combine these commands into macros to automate work.
- Stan is my everyday research tools is a probabilistic programming language featuring fast, highly optimized inference algorithms. It supports a large class of models, with a user base of roughly 10,000.
Last time I want to install the latest emacs on our linux server, cause Emacs can do a lot of things, write code, run R Ess, sending email, and tutorial It is easy to use sudo to handle the problem sudo apt-get install build-essential sudo apt-get build-dep emacs24 Unfortunately, it is always not that easy to install something on a public server, so that you need to build the package from source code.
Stan is one of my faviorate programming language, there are tones of people using stan as daily research or analysis purpose, Facebook’s new pacakge PROPHET. Install R package rstan Rstan is the R interface to stan, which using for statistical modeling, data analysis, and prediction in the social, biological, and physical sciences, engineering, and business. This tutorial will introduce how to install R stan into our computer and how to use R stan in real problem.
If you already know all the stuff which I write in the subtitle, please play around with the following packages rpart, party, partykit. 1. Operation System (OS) Operation System Wiki We are using different operating systems all days, now just focus on your computer: Windows (Our laptop, you need to pay) Unix and Unix like operation system MacOS (Mac, you need to pay) Linux (Server, FREE!!!) ubuntu Our server Lunchbox use this version of Linux mint Debian etc.
