Task: Question Answering
Input (English): In the first scenario we equip the decoder with an additional morphology table including target-side affixes. We place an attention module on top of the table which is controlled by the decoder. At each step, as the decoder samples a character, it searches the table to find the most relevant information which can enrich its state. Signals sent from the table can be interpreted as additional constraints. In the second scenario we share the decoder between two output channels. The first one samples the target character and the other one predicts the morphological annotation of the character. This multi-tasking approach forces the decoder to send morphology-aware information to the final layer which results in better predictions. In the third scenario we combine these two models.  
 Question: How are the auxiliary signals from the morphology table incorporated in the decoder?
Output (English): an additional morphology table including target-side affixes. We inject the decoder with morphological properties of the target language.
