Mixed objective and deep residual coattention for Question Answering

The framework proposed in this research is based on the DCN model (see the preceding diagram), which consists of a coattention encoder and dynamic decoder pointer. The encoder encodes the question and document context separately and then forms a collaborative representation of the both through coattention followed by the decoder outputting the start and end position estimate as per the coattention.

In the new framework of DCN+, two new changes are introduced to the original DCN framework. They are as follows:

  • Adding a deep residual coattention encoder
  • Mixed training objective function which is the combination of the maximum likelihood cross-entropy loss function and reward ...
