Key accomplishments
Assistant Professor, The University of Tennessee, Knoxville
Image Processing
• Developed an image deblurring method based on explicit blur modeling, which was achieved by a mixture of structure-enhanced parameterized kernels.
• Proposed a blur extraction module embedded in a U-Net structure that consisted of cascaded dense dilated convolution (CDDC) and residual integrated pooling (RIP) blocks.
Feature Selection
• Introduced an ensemble model leveraging boosting and stacking with SVM base learners, which enabled an identification of important feature interactions.
• Leveraged XGBoost to apply a gradient boosting search of feature subsets and developed a framework that determined and quantified the importance of feature interactions.
Wind Energy Forecasting
• Proposed a regime-switching ensemble model conforming to wind dynamics by leveraging LSTM and TCN as base learners.
• Analyzed a general input usage of wind power forecasting models established upon an ANN architecture.
Postdoctoral Research Associate, Texas A&M University
• Developed a kernel regression method equipped with a k-NN bandwidth selector and quantified the effect of small device installation on wind turbines.
• Created and published an R package, deployed the package to EDP Renewables, provided a user’s manual, and educated users.
Researcher, Center for Information Security Technologies, Korea University
• Developed analgorithm for a large-scale vehicle routing problem with time windows (VRPTW), which entailed distance-based clustering, constraint-based sub-clustering, and optimization within each sub-cluster.
• Distributed the software (in Java) to Samsung Electronics Logitech.
System Analyst, LG Display
• Analyzed LCDmanufacturing processes by developing programmable logic controller (PLC) level simulation models in AutoMod.
• Accomplished 2% increase on the total productivity of the associated production lines by optimizing PLC logics and delivered the simulation scripts for the company’s usage.
