We just use the pearson similiarity in the KNN model. But friends may want to
use other similiarities. So We should modularize the calculation of similiarity
of KNN model.
KNN算法目前相似度的计算采用person相关系数,需要把这个相��

There are some functions which are too long. We should reduce the length of
these functions.

What steps will reproduce the problem?
1. change the code format
2. test the code with
[http://google-styleguide.googlecode.com/svn/trunk/cpplint/cpplint.py
cpplint.py](a tool to assist with style guide compliance)
3. if the code passes the test,then done; else go to step 1.

我看代码里怎么同时更新了?
for( k=1; k< K_NUM+1; ++k) {
//double tempPu = p[u][k];
p[u][k] += alpha2 * (eui*q[itemI][k] - beta2*p[u][k]);
q[itemI][k] += alpha2 * (eui*p[u][k] - beta2*q[itemI][k]);
}
不是应该固定p,更新q,然后固定q,更新p么?

The unit test is the foundation of refactoring. We should add the test unit
before all our refactoring.

It's quite a while since I read C++ code last time. I do not understand them
quite well now.
Can somebody translate this great package into Python so that other users like
me could be able to tailor the code accordingly.
Thanks.
Happy New Year

There are bugs with svd++ model.
When I used the netflix dataset to test the model, it generated nan error. I am
fixing the bug now.
