Abstract:
Multimodal fusion of audio, vision, and text has demonstrated significant benefits in advancing the performance of several tasks, including machine translation, video captioning, and video summarization. Audio-Visual Scene-aware Dialog (AVSD) is a new and more challenging task, proposed recently, that focuses on generating sentence responses to questions that are asked in a dialog about video content. While prior approaches designed to tackle this task have shown the need for multimodal fusion to improve response quality, the best-performing systems often rely heavily on human-generated summaries of the video content, which are unavailable when such systems are deployed in real-world. This paper investigates how to compensate for such information, which is missing in the inference phase but available during the training phase. To this end, we propose a novel AVSD system using studentteacher learning, in which a student network is (jointly) trained to mimic the teacher’s responses. Our experiments demonstrate that in addition to yielding state-of-the-art accuracy against the baseline DSTC7-AVSD system, the proposed approach (which does not use human-generated summaries at test time) performs competitively with methods that do use those summaries

NEWS MERL work on scene-aware interaction featured in IEEE Spectrum Date: March 1, 2022
MERL Contacts: Anoop Cherian; Chiori Hori; Jonathan Le Roux; Tim K. Marks; Anthony Vetro
Research Areas: Artificial Intelligence, Computer Vision, Machine Learning, Speech & AudioBrief- MERL's research on scene-aware interaction was recently featured in an IEEE Spectrum article. The article, titled "At Last, A Self-Driving Car That Can Explain Itself" and authored by MERL Senior Principal Research Scientist Chiori Hori and MERL Director Anthony Vetro, gives an overview of MERL's efforts towards developing a system that can analyze multimodal sensing information for highly natural and intuitive interaction with humans through context-dependent generation of natural language. The technology recognizes contextual objects and events based on multimodal sensing information, such as images and video captured with cameras, audio information recorded with microphones, and localization information measured with LiDAR.
Scene-Aware Interaction for car navigation, one target application that the article focuses on, will provide drivers with intuitive route guidance. Scene-Aware Interaction technology is expected to have wide applicability, including human-machine interfaces for in-vehicle infotainment, interaction with service robots in building and factory automation systems, systems that monitor the health and well-being of people, surveillance systems that interpret complex scenes for humans and encourage social distancing, support for touchless operation of equipment in public areas, and much more. MERL's Scene-Aware Interaction Technology had previously been featured in a Mitsubishi Electric Corporation Press Release.

NEWS Chiori Hori will give keynote on scene understanding via multimodal sensing at AI Electronics Symposium Date: February 15, 2021
Where: The 2nd International Symposium on AI Electronics
MERL Contact: Chiori Hori
Research Areas: Artificial Intelligence, Computer Vision, Machine Learning, Speech & AudioBrief- Chiori Hori, a Senior Principal Researcher in MERL's Speech and Audio Team, will be a keynote speaker at the 2nd International Symposium on AI Electronics, alongside Alex Acero, Senior Director of Apple Siri, Roberto Cipolla, Professor of Information Engineering at the University of Cambridge, and Hiroshi Amano, Professor at Nagoya University and winner of the Nobel prize in Physics for his work on blue light-emitting diodes. The symposium, organized by Tohoku University, will be held online on February 15, 2021, 10am-4pm (JST).
Chiori's talk, titled "Human Perspective Scene Understanding via Multimodal Sensing", will present MERL's work towards the development of scene-aware interaction. One important piece of technology that is still missing for human-machine interaction is natural and context-aware interaction, where machines understand their surrounding scene from the human perspective, and they can share their understanding with humans using natural language. To bridge this communications gap, MERL has been working at the intersection of research fields such as spoken dialog, audio-visual understanding, sensor signal understanding, and robotics technologies in order to build a new AI paradigm, called scene-aware interaction, that enables machines to translate their perception and understanding of a scene and respond to it using natural language to interact more effectively with humans. In this talk, the technologies will be surveyed, and an application for future car navigation will be introduced.
