A Tutorial Website for Simple Learning - Tutorialspoint

The tutorials library provided by Tutorialspoint covers broad topics in the computer related technology and targets the main points. Self-learners may find the topic they want to learn more accessible and grasp the pin points in a short time. And also it provides online terminal and IDEs for practice.

The tutorial of Hadoop quickly led me to understand the function, structure, and operation of Hadoop as a solution to big data.

An Introductory Book to Data Mining

Discovering Knowledge in Data: An Introduction to Data Mining is a pretty interesting and straightforward book for beginners in data mining. I read 5 chapters of this book just this afternoon. It is so attractive.

The course materials (i.e. data sets, homework, project) of data mining course provided by University of Tennessee can also serve very good practical reference.

SAS Global Certification Program

It is a big data era. People who have data analysis and modeling skills can find plenty of job opportunities. SAS Global Certification Program provides a bridge to enter this profession area by getting them certified.

Based on my own experiences, the procedure of preparing for the certification exam can help study the software and theories specifically and thoroughly in an organized time framework.

Currently I hold the following certificates.

- SAS Certified Base Programmer for SAS 9 (08/2014)
- SAS Certified Advanced Programmer for SAS 9 (12/2014)
- SAS Certified Statistical Business Analyst Using SAS 9: Regression and Modeling (05/2015)
- SAS Certified Predictive Modeler Using Enterprise Miner 7 (06/2015)

I mainly used the SAS online tutor and course notes. If you need any study materials for study purpose only, please leave a comment.

An Introductory Example to Lagrangian Relaxation

The example provided here makes the Lagrangian relaxation (LR) not a mystery for me any more. Each step becomes very clear. I have read a lot of materials in LR. This is one of the best for beginners to get to know how LR works.

An implementation of LR with C++ in ILOG CPLEX can be found here.

That makes me think that there is probably no really unsolvable problems. It is just we haven't found a right way to approach it.
