EXPERIENCE PROJECTS

Confidential

  • Analyzed Large Sample Data for Mortality Analysis of State-Wide Children with Birth Defects.
  • Used SAS extensively to merge information from multiple sources. Performed data cleansing and validation. Produced summary tables and charts, presented results to senior managers.
  • Evaluated effects of demographics and diagnosis on children's mortality by SAS logistic regression.

Confidential

  • Explored Multi-Step Variable Screening for Logistic Regression.
  • Predicted credit score with demographics and financial product usage information. Eliminated trivial variables, screened variables via univariable logistic regression, selected variables through bagging logistic regression. Reduced variable size from 100 to 40.
  • Compared prediction power of logistic regression and L1-norm regularized logistic regression with cross-validation and AUC. L1 regularization was better than logistic regression when using entire variable set. Variable selection improved performance of logistic regression by 10 .

Confidential

Considered 24 variables for predicting credit score. Constructed 1,000 bootstrap samples from dataset of 6,100 samples, conducted logistic regression with backward elimination, forward selection and stepwise selection. Compared agreement between different selection methods across 1,000 bootstrap samples. Over 12 variables were identified significant in less than 500 bootstrap samples.

Confidential

Developed algorithms for image cluster analysis by using variables derived from both visual content and textual captions. Implemented probabilistic model based method to select variables for cluster analysis. Developed genetic algorithm based methods to combine similarities for cluster analysis. Increased image clustering accuracy by 30 than using textual or visual content alone.

Confidential

Enhanced student status tracking and managing. Designed and created tables, queries and reports with Access and SQL server.

Confidential
