CGAL is a powerful C++ library which can be applied in various areas needing geometric computation, ranging from medical imaging to mesh generation. This article will tell you how to set it up in Ubuntu. Before this, I strongly recommend you to read through the official guide of it.
This the first time for me to paint with color using an IPad 2.
I used procreate to paint this picture. It took me about 6 hours finising it.
And this one is painted with Sketchbook Pro.
I together with my two teamates, two teachers and two school mates went to Taiwan for 5 days from 2013.8.26 to 8.30 to attend TECO Green Technology Contest 2013. We had a great time in this 5 days.
Day 1 Arriving
We arrived at Taiwan in Taoyuan International Airport at about 12 AM after which we[……]

If you have installed R in your Ubuntu and you need to some machine learning work on it, Rattle is recommended.
You may met problems when installing RGtk2, like this:
GNU/Linux: configure: error: GTK version 2.8.0 required
The Relationship Between Data Mining and Machine Learning
Its been a long time since I get to know about such concepts as: Data Mining, Machine Learning, Artificial Intelligence, Pattern Recognition and etc.. However, they are in a kind of mess and its hard to figure out the relationship between th[……]
Mahout integrates a lot of common machine learning algorithms which faciliates those who want to do some research in data mining. It is based on Java and a lot of need to be done before you can make it work. At least you will need JDK, Eclispse, Hadoop and Mahout. But I strongly recommend all those[……]
I’d spent two weeks on Netlogo Manual and a tutorial on youtube before I wrote this program. Netlogo is a good agent based simulation platform while its math calculation ability is poor which can be compensated by R-extension.
This program is to simulate the video recommendation on Video sites su[……]
I attend Andrew Ng’s Machine Learning courses on Coursera recently. And he recommend us to use GNU Octave to do some calculation.
Actually, GNU Octave is very powerful as it is said on the title: Matlab’s
Vim is a powerful text editor and it is the most popular one for Linux users.
For details of it you can go to https://en.wikipedia.org/wiki/Vim_%28text_editor%29
And Vim is usually installed as defaut for Ubuntu users. You only need to type “vim” in the terminal and you can get access to it.[……]
Netlogo is a powerful platform for simulation while its mathimatical calculation is relatively poor comparing to some specific softwares. So it is a good idea to embedd R in Netlogo so that the problem can be solved. This article will show you hao to do the “A” in the upside picture which comes[……]

Andrew Ng came to Beijing to give two lectures this Tuesday, one in Baidu and another in Tsinghua U.. And I was very lucky to go to his lecture in Tsinghua to be acknowledged with his ideas in Machine Learning.
I’ve been focusing on Big Data and Data Mining for several months. From where I stan[……]
ABS is short for Agent Based Simulation, or Agent Based Modeling. I was acknowledged to this from my tutor, Pro.Guo. She is doing some research in data mining and some of her projects are on the recommendation algorithm applied to video websites such as Youtube. And the problem is that the tradition[……]
