I am a member of the research faculty (assistant research scientist) at the University of Maryland,
associated with the Computer Vision Lab and the Institute for
Advanced Computer Studies. I received my doctoral degree in Computer
Science at the University of Maryland, College Park, with Prof. Larry Davis
as my advisor. I completed my B.S. and M.S. degrees at Penn State University with Prof.
Octavia Camps as my research advisor.
Research interests: I am interested in high-level commonsense
reasoning about the visual world in the face of observation and model
uncertainty. Ultimately, I would like to build a system that can answer
complex visual queries that are expressed linguistically and are not known
ahead of time. This involves investigating knowledge representations that
manage the trade-off between expressiveness and computational complexity;
learning rich spatial and temporal models while managing the trade-off between the amount of
model structure, training data, and supervision; and, reducing uncertainty in mid- and
low-level computer vision techniques.
My interests lie at the intersection of computer vision, artificial intelligence, and machine
learning. Click on a topic to see related publications: computer vision -
event modeling and retrieval,
object detection and classification,
tracking,
action recognition;
artificial intelligence -
knowledge representation and reasoning,
natural language processing;
machine learning -
large (web-)scale machine learning,
graphical models,
classification,
kernel density estimation,
deep learning.

Software
FIGTree - Fast Improved Gauss Transform with Tree Data Structure
(FIGTree Homepage)
A library for fast computation of Gauss transforms in multiple
dimensions, using the Improved Fast Gauss Transform and Approximate
Nearest Neighbor searching. The nearest neighbor searching is
performed using the ANN library, available at
http://www.cs.umd.edu/~mount/ANN/.
This software allows for efficient computation of probabilities by
Kernel Density Estimation (KDE), and can reduce complexity of
algorithms commonly used in Computer Vision, Machine Learning, etc,
that must evaluate the Gauss transform. The publication describing
the newest improvements in the code is the NIPS 2008 paper by
Morariu et al. Previous publications related to this approach are
provided on
Vikas Raykar's page.
