About Hui Wu

I am a senior research scientist and a manager at the Distributed MLOps group @ IBM Research. I am passionate about developing new AI applications that drive real-world impact, particulary around Edge AI use cases. My current interest includes vision and language, neural-symbolic learning, computer vision for fashion and more recently, distributed MLOps. I joined IBM Research since 2015, and worked in the computer vision and multimedia group at IBM Research AI (2015-2020), and MIT-IBM Watson AI Lab (2020-2021). Prior to joining IBM, I received my PhD in Computer Science from UNC Charlotte, with a thesis focus on machine learning techniques applied to image set analysis problems.

Selected Projects

Dialog-based Interactive Image Retrieval

Dialog-based Interactive Image Retrieval

NeurIPS 2018 [PDF] [CODE] [DEMO]


We proposed a novel type of dialog agent for the task of interactive image retrieval. Recently, there has been a rapid rise of research interest in visually grounded conversational agents, driven by the progress of deep learning techniques for both image and natural language understanding. A few interesting application scenarios have been explored by recent work, such as collaborative drawing, visual dialog and object guessing game. In this work, we tested the value of visually grounded dialog agents in a practical and yet challenging context. Specifially, we proposed a novel framework of image retrieval system which learns to seek natural and expressive dialog feedbacks from the user and iteratively refine the retrieval result.

Semantic-aware Food Visual Recognition

Learning to make better mistakes - Semantics-aware visual food recognition
Hui Wu, Michele Merler, Rosario Uceda-Sosa and John R. Smith
ACM Multimedia, 2016 [PDF] [Watson API]

The growing popularity of fitness applications and people’s need for easy logging of calorie consumption on mobile devices has made accurate food visual recognition increasingly desireable. In this project, we proposed a visual food recognition framework that integrates the semantic relationships among fine-grained food classes.
