Modular Visual Question Answering via Code Generation

ACL 2023short

We present a framework that formulates visual question answering as modular code generation. In contrast to prior work on modular approaches to VQA, our approach requires no additional training and relies on pre-trained language models (LMs), visual models pre-trained on image-caption pairs, and fif…

TL;DW? Summarizing Instructional Videos with Task Relevance & Cross-Modal Saliency

ECCV 2022poster

"YouTube users looking for instructions for a specific task may spend a long time browsing content trying to find the right video that matches their needs. Creating a visual summary (abridged version of a video) provides viewers with a quick overview and massively reduces search time. In this work,…

Multi-Person 3D Motion Prediction with Multi-Range Transformers

NeurIPS 2021poster

We propose a novel framework for multi-person 3D motion trajectory prediction. Our key observation is that a human's action and behaviors may highly depend on the other persons around. Thus, instead of predicting each human pose trajectory in isolation, we introduce a Multi-Range Transformers model…

Seeing the Un-Scene: Learning Amodal Semantic Maps for Room Navigation

ECCV 2020poster

We introduce a learning-based approach for room navigation using semantic maps. Our proposed architecture learns to predict top-down belief maps of regions that lie beyond the agent’s field of view while modeling architectural and stylistic regularities in houses. First, we train a model to generate…

Straight to the Facts: Learning Knowledge Base Retrieval for Factual Visual Question Answering

ECCV 2018poster

Question answering is an important task for autonomous agents and virtual assistants alike and was shown to support the disabled in efficiently navigating an overwhelming environment. Many existing methods focus on observation-based questions, ignoring our ability to seamlessly combine observed cont…
