Abstract

One of the core challenges in Visual Dialogue problems is asking the question that will provide the most useful information towards achieving the required objective. Encouraging an agent to ask the right questions is difficult because we don't know a-priori what information the agent will need to achieve its task, and we don't have an explicit model of what it knows already. We propose a solution to this problem based on a Bayesian model of the uncertainty in the implicit model maintained by the visual dialogue agent, and in the function used to select an appropriate output. By selecting the question that minimises the predicted regret with respect to this implicit model the agent actively reduces ambiguity. The Bayesian model of uncertainty also enables a principled method for identifying when enough information has been acquired, and an action should be selected. We evaluate our approach on two goal-oriented dialogue datasets, one for visual-based collaboration task and the other for a negotiation-based task. Our uncertainty-aware information-seeking model outperforms its counterparts in these two challenging problems.

  • In 2020, Harris et al. [644] used MixUp, FMix, FastText-300d, CNN, FastText, bidirectional LSTM, and BERT with a relative entropy objective for image, audio, text, and point cloud classification on CIFAR-10, Fashion MNIST, and ImageNet.

    The Experiments and GuessWhat sections describe goal-oriented dialogue tasks and an RNN questioner, not mixed-sample augmentation or classification on CIFAR-10, Fashion MNIST, and ImageNet. Searches for MixUp, FMix, FastText-300d, and a relative-entropy classification objective found no passage supporting the attributed study; the paper's text also does not establish who conducted that study.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
