Are the OnlineLogisticRegression s of a CrossFolderLearner object equal after trainning?

[XiaoboGu]

Hi,
        The TrainNewsGroup.java just use OnlineLogisticRegression model = 
state.getModels().get(0); to get an OLR object to do the overall description of 
the AdaptiveLogisticRegression’s performance, there are two questions:
1. Are the OLR objects of the best CrosFolderLearner equal.
2. According to what cretirear, the best CrossFolderLearner object is chosen?
