Margin Infused Relaxed Algorithm

This method is used by Watanabe et al., EMNLP 2007 to train an MT system a with a very large number of features of the order of millions. The training step was performed using a specific algorithm called the Margin Infused Relaxed Algorithm (MIRA) proposed by

Summary

MIRA is an online large-margin training algorithm which updates the weight vector according to certain margin constraints and loss function. It is used to learn the weights of features after processing each training instance.
