My research interests lie at the intersection of machine learning and computer vision,
with a focus on developing intelligent systems that are able to
- concisely summarize their beliefs about the world with diverse plausible predictions,
- integrate information and beliefs across different sub-components or `modules' of AI (vision, language, reasoning), and
- and explain why they believe what they believe.
On the machine learning front, I develop tools such as
On the computer vision front, I focus on
- producing diverse outputs from structured and neural models
- structured-output prediction
- large-scale distributed inference and learning in graphical models such as Markov Random Fields
My Google Scholar profile.
- holistic scene understanding
- object/person detection and segmentation
- co-segmentation in multiple images
