Panda (Predictive Advanced
Nonlinear Diagnostic
Analyzer, Aditya Tayal, Yuying Li, Tom Coleman), ranks the fourth place in the Heritage Health Provider Network
Competition.
In
2006 over $30 billion was spent on unnecessary hospital admissions in the
United States. In an effort to
address this extraordinary challenge, the Heritage Provider Network (HPN) https://www.heritagehealthprize.com,
sponsored a global incentivized competition. The objective: to create an algorithm
that uses patient data to predict hospitalizations. The competition ran for two years
(ending April 4,2013) with a grand prize of $3 million. It attracted over
1600 teams with participants from various disciplines around the world,
including data scientists, biostatisticians, physicians, engineers, industry
players. Note: Winner and
placement among top 10 will be revealed publicly on June 3/4 at the Health DataPalooza Conference.
How we
made it to the 4th place?

My current research interest is data mining and
computational finance. I am generally interested in algorithm design,
analysis, and implementation for scientific computing problems. More
specifically, I am interested in:
 Data mining:
supervised, semisupervised learning, feature selection, ordinal
regression, similarity measure
 Fraud detection, e.g.,
unsupervised auto insurance fraud detection
 Computational finance
 Computational methods
for optimization
 Trust region methods
 Large scale
optimization
 Image restoration and
segmentation
