• Optimal decision making via machine learning
• Stochastic optimization and Monte Carlo simulation
• Geometric modeling under uncertainty

Research area

Geometric Modeling under Uncertainty

We have studied various aspects of geometric modeling. Recently, we use machine learning techniques to handle uncertainty in geometric modeling. We typically use probabilistic graphical models to represent geometric variables tied with observed values.

Recent research projects are :
    - 3D Reconstruction from Freehand Ultrasound Images
    - Combining volumetric CT and optical scan data



Stochastic Optimization

We are also interested in stochastic optimization problems such as stochastic approximation and simulation optimization. techniques.

Recent research projects are :
    - Global root finding with Gaussian Process Regression
    - Simulation optimization for military RAM problem




Monte Carlo Simulation

Since many real systems are very large, complex and non-tractable in analytic way, simulation often gives important intuition and approximate solutions. We work on efficient Monte Carlo simulation and other computer experiments.  

Some of the research topics in this domain are :
    - Denoising Monte Carlo sensitivity estimates
    - Bayesian Design of Computer Experiments
