说明： CF svdFeature, 基于C++开发的，利用svd奇异矩阵分解建立的协同过滤工具箱。可以解决常用的所有协同过滤问题。对于推荐系统的建立至关重要，是很好的学习和使用的工具箱。协同滤波也是最有机器学习感觉的方法之一，我们大家都爱它！
(CF svdFeature, a well performed toolkit of confiltering method based on svd, which is developed using C++ programming language. It could almost solve all common cofitering problems.)

----BUILD:LINUX----
make
----BUILD:WINDOWS----
require MS Visual Studio, see VS2005 folder for sln file, use x*** on ***bit machine
(1) create a empty project for each exes
(2) for each exec listed, add files to project:
(2.1) svd_feature.exe
* svd_feature.cpp
* apex_svd.cpp
* apex_svd_data.cpp
(2.2) svd_feature_infer.exe
* svd_feature_infer.cpp
* apex_svd.cpp
* apex_svd_data.cpp
(2.3) line_shuffle.exe
* line_shuffle.cpp
(2.4) make_feature_buffer.exe
* make_feature_buffer.cpp
* apex_svd_data.cpp
(2.5) make_ugroup_buffer.exe
* make_ugroup_buffer.cpp
* apex_svd_data.cpp

----CHANGE LOG----
1.0 2011-07-11: first release
1.1 2011-09-17: add efficient computation of SVD++, better support for rank-model, removed dependecy on dSFMT
1.1.2 2011-09-21: add document for code interface, fix a bug that occurs in windows, add different kinds of regularization options
1.1.3 2011-10-07: add detailed regularization setting, fix a bug that only occurs in windows
1.1.4 2011-10-12: fix a bug related in rank-model, more robust input buffering for user grouped format, less memory cost for loading input data
1.1.5 2011-11-21: Add support for common parameter space of user/item features. This allows interesting usage such as joint matrix factorization and symmetric relation prediction
1.1.6 2011-12--2: Add lite version of SVDFeature(apex_svd_lite.cpp), used for example purpose for SGD implementation
