Understanding scenes and events through joint parsing, cognitive reasoning and lifelong learning

Lead Research Organisation: University of Oxford
Department Name: Engineering Science

Abstract

The goal of this MURI team is to develop machines that have the following capabilities:
i) Represent visual knowledge in probabilistic compositional models in spatial, temporal, and causal hierarchies augmented with rich attributes and relations, use task-oriented representations for efficient task-dependent inference from an agent's perspective, and preserve uncertainties;
ii) Acquire massive visual commonsense via web scale continuous lifelong learning from large and small data in weakly supervised HCI, and maintain consistence via dialogue with humans;
iii) Achieve deep understanding of scenes and events through joint parsing and cognitive reasoning about appearance, geometry, functions, physics, causality, intents and belief of agents, and use joint and long-range reasoning to fill the performance gap with human vision;
iv) Understand human needs and values, interact with humans effectively, and answer human queries about what, who, where, when, why and how in storylines through Turing tests.

Results and Impact The interaction between language and vision, despite seeing traction as of late, is still largely unexplored. This is a particularly relevant topic to the vision community because humans routinely perform tasks which involve both modalities. We do so largely without even noticing. Every time you ask for an object, ask someone to imagine a scene, or describe what you're seeing, you're performing a task which bridges a linguistic and a visual representation. The importance of vision-language interaction can also be seen by the numerous approaches that often cross domains, such as the popularity of image grammars. More concretely, we've recently seen a renewed interest in one-shot learning for object and event models. Humans go further than this using our linguistic abilities; we perform zero-shot learning without seeing a single example. You can recognize a picture of a zebra after hearing the description "horse-like animal with black and white stripes" without ever having seen one.

Furthermore, integrating language with vision brings with it the possibility of expanding the horizons and tasks of the vision community. We have seen significant growth in image and video-to-text tasks but many other potential applications of such integration - answering questions, dialog systems, and grounded language acquisition - remain largely unexplored. Going beyond such novel tasks, language can make a deeper contribution to vision: it provides a prism through which to understand the world. A major difference between human and machine vision is that humans form a coherent and global understanding of a scene. This process is facilitated by our ability to affect our perception with high-level knowledge which provides resilience in the face of errors from low-level perception. It also provides a framework through which one can learn about the world: language can be used to describe many phenomena succinctly thereby helping filter out irrelevant details.

Topics covered (non-exhaustive):

language as a mechanism to structure and reason about visual perception,
language as a learning bias to aid vision in both machines and humans,
novel tasks which combine language and vision,
dialogue as means of sharing knowledge about visual perception,
stories as means of abstraction,
transfer learning across language and vision,
understanding the relationship between language and vision in humans,
reasoning visually about language problems,
visual captioning, dialogue, and question-answering,
visual synthesis from language,
sequence learning towards bridging vision and language,
joint video and language alignment and parsing, and
video sentiment analysis.
