• Title: Multi-View Attention Network for Visual Dialog
• Authors: Sungjin Park, Taesun Whang, Yeochan Yoon, Heuiseok Lim
• Abstract summary: It is necessary for an agent to 1) determine the semantic intent of question and 2) align question-relevant textual and visual contents. We propose Multi-View Attention Network (MVAN), which leverages multiple views about heterogeneous inputs. MVAN effectively captures the question-relevant information from the dialog history with two complementary modules.

• Abstract: Visual dialog is a challenging vision-language task in which a series of questions visually grounded by a given image are answered. To resolve the visual dialog task, a high-level understanding of various multimodal inputs (e.g., question, dialog history, and image) is required. Specifically, it is necessary for an agent to 1) determine the semantic intent of question and 2) align question-relevant textual and visual contents among heterogeneous modality inputs. In this paper, we propose Multi-View Attention Network (MVAN), which leverages multiple views about heterogeneous inputs based on attention mechanisms. MVAN effectively captures the question-relevant information from the dialog history with two complementary modules (i.e., Topic Aggregation and Context Matching), and builds multimodal representations through sequential alignment processes (i.e., Modality Alignment). Experimental results on VisDial v1.0 dataset show the effectiveness of our proposed model, which outperforms the previous state-of-the-art methods with respect to all evaluation metrics.

  We introduce Multi-round Dialogue State Tracking model (MDST) MDST captures each round of dialog history, constructing internal dialogue state representations defined as 2-tuples of vision-language representations. Experimental results on the VisDial v1.0 dataset demonstrate that MDST achieves a new state-of-the-art performance in generative setting.

  Multimodal Dialogue Response Generation (MDRG) is a recently proposed task where the model needs to generate responses in texts, images, or a blend of both. Previous work relies on the text modality as an intermediary step for both the image input and output of the model rather than adopting an end-to-end approach. We propose BI-MDRG that bridges the response generation path such that the image history information is utilized for enhanced relevance of text responses to the image content.

  In mixed-initiative conversational search systems, clarifying questions are used to help users who struggle to express their intentions in a single query. We hypothesize that in scenarios where multimodal information is pertinent, the clarification process can be improved by using non-textual information. We collect a dataset named Melon that contains over 4k multimodal clarifying questions, enriched with over 14k images. Several analyses are conducted to understand the importance of multimodal contents during the query clarification phase.

  We propose a model framework without bounding boxes to understand the causal nexus of object semantics in images. We implement a mutual relation attention module to model sophisticated and deeper visual semantic relations between instance objects and background information. Our proposed attention model can further analyze salient image regions by focusing on important word-related questions.

  The Visual Dialog task requires a model to exploit both image and conversational context information to generate the next response to the dialogue. We show that previous joint-modality (history and image) models over-rely on and are more prone to memorizing the dialogue history. We present methods for this integration of the two models, via ensemble and consensus dropout fusion with shared parameters.
