Yanchao Yu, Arash Eshghi, Oliver Lemon · 2017
We present VOILA: an optimised, multimodal dialogue agent for interactive learning of visually grounded word meanings from a human user.VOILA is: (1) able to learn new visual categories interactively from users from scratch; (2) trained on real human-human dialogues in the same domain, and so is able to conduct natural spontaneous dialogue; (3) optimised to find the most effective trade-off between the accuracy of the visual categories it learns and the cost it incurs to users.VOILA is deployed on Furhat 1 , a humanlike, multi-modal robot head with backprojection of the face, and a graphical virtual character.
