摘    要：
The recommendation system is widely used in the web service and online 
shopping. Due to the increasing of the customers and goods, the computation 
cost is challenged in practical. Even the O(n) algorithm can not accomplish the 
real time response. In this talk, I will introduce the main concept of the 
recommendation search engine. The general tools, such as PCA and SVD, are 
widely used in this field. However, such kernel methods are computational cost. 
To perform the real time service, the computational complexity must reduce to 
constant time.
