![Dynamic Temporal Contextualized
The answer provided
by one of the
interlocutor affects
the state of the
dialogue
What is dialogue?
The interpretation of
each utterance
depends incredibly on
different environment
conditions
Different topics are
discussed in a given
conversation without
a specific order

- 5. RQ1 : Is it possible to train a conversational agent to interact within real world contexts consisting of embodied agents and situated objects?
- 6. RQ2: Is it possible to train a conversational agent to generate accurate contextualized responses for the user?
- 7. RQ3: Is the system able to adapt seemly to different domains by exploiting what it has previously learned?
- 9. Thanks! You can find me at the poster session @ale_suglia as247@hw.ac.uk Any questions?
