Extending Universal Semantic Tagging
Department of Computer Science, Rutgers UniversityProject Goal: To produce a large database that provides semantic properties of words.
• Preprocessed data from University of Groningen's Parallel Meaning Bank (PMB) Project.
• Collected statistics such as words count for each semantic tag, total words in the database, as well as other statistics from the PMB Project dataset.
• Produced semantic tag vectors from the PMB project dataset.
• Predicted semantic tags of English words by computing the mean of semantic tag vectors of the k Nearest Neighbor words which are computed using word vectors from Stanford University’s GloVe Project as well as the English Lemma + Part of Speech Embedding from Sketch Engine.
• Analyzed different methods of computing nearest neighbors by generating confusion matrices and perform manual error analysis.
• Produced a cross-lingual database that provides semantic properties of words in 370 languages including English, German, Dutch, Italian and Mandarin Chinese.

Machine Learning and IoT (blue team)
WINLAB, Rutgers University• Designed an end-to-end security-conscious IoT framework using openHAB Framework, InfluxDB Database,TI CC2650 Sensortags, and Z-wave devices
• Implemented Python program to collect data (such temperature, humidity, light, etc.) from CC2650 sensortag over Bluetooth using Bluepy library.
• Implemented realtime data analysis program to monitor the gradient of temperature data from coffee machine over 5 minutes using a sliding window. Send notification when coffee is ready.
• Constructed and implemented Hidden Markov Model to predict the probability of "coffee pot is empty". [Hidden Markov Model for Coffee Machine]
• Used various regression models to predict future data based on past time series data and achieved anomaly detection of our IoT system.

microMVP (micro multi-vehicle platform)
Department of Computer Science, Rutgers University• Designed algorithm to resample robots' path points with uneven density to path points with uniform density while preserving collision free path.
• Implemented a real-time multi-agent navigation algorithm by applying the concept of Reciprocal Velocity Obstacle (RVO)
• Applied the navigation algorithm to Micro MVP project.
• Redesigned the 3D shell of micro vehicle in Blender
• Used 3D printing to produce robot shells

Autonomous Robot Packaging System
School of Engineering, Rutgers University• Learned and used Robot Operating System (ROS) to control individual joint of Manipulator-H manipulator.
• Using the base of first joint as origin, constructed a 3D Cartesian coordinate system.
• Used various robot path planning algorithms such as 3D Rapidly-Exploring Random Trees (RRT) to obtain collision free path for Manipulator-H.
• Applied path planning algorithms to both rviz simulator and the actual robot.
