related classes in relation extraction

... by first using the flat learning strat- egy to learn the discriminative functions for indi- vidual classes and then iteratively combining the two most related classes using the cosine similar- ity ... from the given training set repeatedly. Then, each training sample set is used to train a certain discrimina- tive function. Finally, the final weight vector in the discriminative function is ... vector initialized as the zero vector. 2) Train the weight vector of the linear discriminative function for the “AT” relation type vs. all the remaining relation types (including the “NON” relation) ...
