... context can lead to combinatorial explo-sion of the feature space. When the feature space is huge (e.g., in the order of tens of millions of features or even more), the SGC algorithm ex-ceeds ... values of y and an empty feature set. For each candidate feature in a predefined feature space, it computes the likelihood gain achieved by includ-ing the feature in the model. The feature ... correspond to the selected features. Then, the SGC algorithm is performed on each of the feature groups and new features are se-lected from each of them. In other words, the feature space splitting...
