Class Project

Wireless Price Display System

This project was my final team project for "Electrical Engineering Laboratory 3" class in 2004 (when I was junior in college). The goal was to make a wireless system that substitutes price tags with electrical displays in grocery stores. The base station manages a list of products in the database, and it sends out price information to receiver units. Receiver units are simple character displays having unique IDs. When any products' prices change, the system can easily update new prices on these displays. 

Large-scale News Image Analysis with MapReduce-based LSH and VisualRank

Hao Li (Ph.D. student from CS) and I conducted a big-data analysis project using the MapReduce framework (Hadoop) for the final project of INFM718G (Data-Intensive Computing with MapReduce, by Dr. Jimmy Lin). Targeting all the news images in April 2013, we tried to rank news images based on the importance and popularity level of each news image. To do that, we extracted image features using SIFT (Scale-invariant feature transform) and constructed a graph of images using LSH (Locality-sensitive Hashing) as a means to approximate the similarity of images.

Information Environment Analysis for the Korean Cultural Center D.C.

Bryon Baumstarck (MIM student, class of 2014) and I conducted this project as the final project of INFM 600 (Information Environment, by Dr. Jessica Vitak) in 2012 to analyze the information environment of the Korean Cultural Center, a branch of Embassy of South Korea in Washington DC. The theoretical model that we used was Davenport and Prusak's six components of the ecological model for information management (1997).

Cozy Street Blocks

This was the final project of the "Theories and Practices in Intelligent Convergence Systems" class from the Graduate School of Convergence Science and Technology in 2009. The goal of this system was (1) to grow plants in an urban environment in a controlled way; (2) to change urban places into eco-friendly and entertaining spaces; and (3) to make use of street blocks as a medium for providing urban information to citizens. Our team of students presented designs of the software/hardware architectures of the blocks and user scenarios. 

Our team received A+ in this course.
