%A Hong-Thinh Nguyen %T RNN on Machine Reading Comprehension Bi-Directional Attention Flow model %X Although end-to-end deep neural network have gained popularity in the last few years and have been successful in several Natural Language Processing tasks, reading comprehension remains a challenging one. In this report, we presents in details the popular Bi-Directional Attention Flow model which represents the context at different level and combined the context-to-query and query-to-context direction attention. All necessary background knowledge of general Recurrent Neural Network is also discussed. %K RNN, Natural Language Processing %D 2017 %C University of Engineering and Technology %I University of Engineering and Technology %L SisLab2912
