Research

Learning A Bregman Distance Function.		It learns a distance function rather than a metric to avoid Curse of Dimensionality.	2009
Probabilistic Relevant Component Analysis (pRCA)		It extends the RCA from hard constraints to probabilistic constraints, and provide a method to generate the probabilistic constraints from noisy data.	2009
Semantic Preserving Bag-of-Words Model (SPBoW)		It proposes the measurement for semantic gap and learns a semantic visual dictionary for each object by minimizing the gap.	2009
Learning to Tag		It learns a recommendation function based on both tags and visual information that helps social tagging.	2008
Flickr Distance		It uses the visual correlation to measure the relationship between concepts.	2008
Visual Language Model (VLM)		The model represents each object category as a language model, which efficiently captures the spatial information of visual words via conditional distributions.	2007
Mutually Beneficial Learning (MBL)		It boosts multiple learners by sharing their knowledge to each other.	2007
Volume Graph Model (VGM)		This model helps to extract 3D surfaces from the Volume data.	2006
3D Face Reconstruction		It can reconstruct 3D face from a photo and a sequence of MRI images.	2006
